A plant species in the CHENOPODIUM genus known for edible greens.
A class of plants within the Bryophyta comprising the mosses, which are found in both damp (including freshwater) and drier situations. Mosses possess erect or prostrate leafless stems, which give rise to leafless stalks bearing capsules. Spores formed in the capsules are released and grow to produce new plants. (Concise Dictionary of Biology, 1990). Many small plants bearing the name moss are in fact not mosses. The "moss" found on the north side of trees is actually a green alga (CHLOROPHYTA). Irish moss is really a red alga (RHODOPHYTA). Beard lichen (beard moss), Iceland moss, oak moss, and reindeer moss are actually LICHENS. Spanish moss is a common name for both LICHENS and an air plant (TILLANDSIA usneoides) of the pineapple family. Club moss is an evergreen herb of the family LYCOPODIACEAE.

Plant polyploidy and non-uniform effects on insect herbivores. (1/197)

Genomic duplication through polyploidy has played a central role in generating the biodiversity of flowering plants. Nonetheless, how polyploidy shapes species interactions or the ecological dynamics of communities remains largely unknown. Here we provide evidence from a 4 year study demonstrating that the evolution of polyploidy has reshaped the interactions between a widespread plant and three species of phytophagous moths. Our results show that polyploidy has produced non-uniform effects, with polyploids less attacked by one insect species, but significantly more attacked by two other species. These results suggest that the evolution of plant polyploidy may not generally confer uniform resistance to multiple species of insect herbivores. In the absence of such a uniform release, the extreme evolutionary success of polyploid plants is probably due to factors other than escape from herbivory. Together, these results suggest that a primary consequence of plant polyploidy may be to shape the ecological structure of plant-insect interactions, thereby providing opportunities for diversification in both plant and insect taxa.  (+info)

Occurrence of polygodial and 1-(2,4,6-trimethoxyphenyl)-but-2-en-1-one from some ferns and liverworts: role of pungent components in bryophytes and pteridophytes evolution. (2/197)

The New Zealand fern Blechnum fluviatile and liverwort, Hymenophyton flabellatum produce the characteristic pungent compounds, (-)-polygodial, a sesquiterpene dialdehyde, and 1-(2,4,6-trimethoxyphenyl)-but-2-en-1-one, respectively. The former compound has been isolated from the Japanese liverwort, Porella vernicosa complex and the latter one from the Japanese fern, Arachinoides standishii. The occurrence of both compounds in both pteridophytes and bryophytes provides another important link between bryophytes and ferns.  (+info)

Indication of global deforestation at the Cretaceous-Tertiary boundary by New Zealand fern spike. (3/197)

The devastating effect on terrestrial plant communities of a bolide impact at the Cretaceous-Tertiary boundary is shown in fossil pollen and spore assemblages by a diverse flora being abruptly replaced by one dominated by a few species of fern. Well documented in North America, this fern spike signals widespread deforestation due to an impact winter or massive wildfires. A Southern Hemisphere record of a fern spike, together with a large iridium anomaly, indicates that the devastation was truly global. Recovery of New Zealand plant communities followed a pattern consistent with major climatic perturbations occurring after an impact winter that was possibly preceded by global wildfires.  (+info)

Characterization of mutations that feminize gametophytes of the fern Ceratopteris. (4/197)

Gametophytes of the fern Ceratopteris are either male or hermaphroditic. Their sex is epigenetically determined by the pheromone antheridiogen, which is secreted by the hermaphrodite and induces male and represses female development in other young, sexually undetermined gametophytes. To understand how antheridiogen represses the development of female traits at the genetic level, 16 new mutations that feminize the gametophyte in the presence of antheridiogen were identified and characterized. Seven are very tightly linked to the FEM1 locus previously described. Nine others define another locus named NOTCHLESS1 (NOT1), as several of the not1 mutants lack a meristem notch. Some not1 mutations also affect sporophyte development only when homozygous, indicating that the not1 mutations are recessive and that NOT1 is also required for normal sporophyte development. The epistatic interactions among FEM1, NOT1, and other sex-determining genes are described. This information was used to expand the genetic model of the sex-determining pathway in Ceratopteris. On the basis of this model, we can say that the presence of antheridiogen leads to the activation of the FEM1 gene, which not only promotes the differentiation of male traits, but also represses female development by activating the NOT1 gene. NOT1 represses the TRA genes necessary for the development of female traits in the gametophyte.  (+info)

Cell cycle arrest allows centrin translation but not basal body formation during spermiogenesis in Marsilea. (5/197)

Spermiogenesis in the water fern Marsilea vestita is a rapid process that requires the de novo formation of basal bodies in a cytoplasmic particle known as a blepharoplast. Spermiogenesis is activated by placing dry spores into water and is dependent upon the translation of new proteins from stored mRNAs with little, if any, new transcription. We looked at the necessity of cell division cycles in the gametophyte as a prerequisite for the activation of centrin translation and for the consequent formation of blepharoplasts. Cell cycle arrest was induced by treatments of gametophytes with hydroxyurea, with olomoucine, or after RNAi, employing dsRNA derived from Marsilea cyclin A or cyclin B. In all cases, centrin is translated from stored mRNA at the normal time, approximately 4 hours after imbibition, and it accumulates to maximal levels approximately 6 hours after imbibition. In spite of the fact that centrin is translated at essentially normal times and accumulates to nearly normal levels, no blepharoplasts form in the gametophytes where division cycles have been disrupted. These results provide a clear demonstration that the new translation of centrin, by itself, is insufficient for blepharoplast formation, the de novo formation of basal bodies, and the assembly of a motile apparatus.  (+info)

Isolation and identification of antheridiogens in the ferns, Lygodium microphyllum and Lygodium reticulatum. (6/197)

Antheridiogens in culture media of 6-week-old prothallia of two species of Schizaeaceous ferns, Lygodium microphyllum and Lygodium reticulatum, were analyzed by gas chromatography-mass spectrometry. In both species, the gibberellin A73 methyl ester (GA73-Me) was identified as the most abundant antheridiogen, and the methyl esters of GA9 and of several monohydroxy-GA73 derivatives were also detected. Since both species produced antheridiogens at a high level, they were classified into high-antheridiogen-producing ferns. The response to GA73-Me of gametophytes of both species is also discussed.  (+info)

New bitter-tasting hemiterpene glycosides from the Japanese fern Hymenophyllum barbatum. (7/197)

Hymenosides G--J were newly isolated from the Japanese fern Hymenophyllum barbatum, in addition to hymenosides A--F. The structures of hymenosides were elucidated by extensive two-dimensional nuclear magnetic resonance and/or chemical evidence. The structures of those aglycones were divided into three types, 1,4-dihydroxy-2-hydroxymethyl-but-2-ene, 1,4-dihydroxy-2-methyl-but-2-ene, and 3-hydroxy-5-hexanolide. The sugar moieties were also established by chemical and spectroscopic methods, which were acylated by phenylacetic acid derivatives. These glycosides had a bitter or weakly pungent taste.  (+info)

Plant expansins are a complex multigene family with an ancient evolutionary origin. (8/197)

Expansins are a group of extracellular proteins that directly modify the mechanical properties of plant cell walls, leading to turgor-driven cell extension. Within the completely sequenced Arabidopsis genome, we identified 38 expansin sequences that fall into three discrete subfamilies. Based on phylogenetic analysis and shared intron patterns, we propose a new, systematic nomenclature of Arabidopsis expansins. Further phylogenetic analysis, including expansin sequences found here in monocots, pine (Pinus radiata, Pinus taeda), fern (Regnellidium diphyllum, Marsilea quadrifolia), and moss (Physcomitrella patens) indicate that the three plant expansin subfamilies arose and began diversifying very early in, if not before, colonization of land by plants. Closely related "expansin-like" sequences were also identified in the social amoeba, Dictyostelium discoidium, suggesting that these wall-modifying proteins have a very deep evolutionary origin.  (+info)

Leptosporangiate ferns are the largest group of living ferns, including some 11000 species worldwide.[1] They constitute the subclass Polypodiidae,[2][3] but are often considered to be the class Pteridopsida or Polypodiopsida,[4] although other classifications assign them a different rank.[5] The leptosporangiate ferns are one of the four major groups of ferns, with the other three being the Eusporangiate ferns comprising the marattioid ferns (Marattiidae, Marattiaceae), the horsetails (Equisetiidae, Equisetaceae), and whisk ferns and moonworts.[3][4]. There are approximately 8465 species of living leptosporangiate ferns, compared with about 2070 for all other ferns, totalling 10535 species of ferns.[2] Almost a third of leptosporangiate fern species are epiphytes.[6]. These ferns are called leptosporangiate because their sporangia arise from a single epidermal cell and not from a group of cells as in eusporangiate ferns (a polyphyletic lineage). The sporangia are typically covered with a scale ...

Harts tongue fern (Asplenium scolopendrium, also known as Phyllitis scolopendrium) is a European member of a very large family of ferns, the Aspleniaceae, or spleenwort family. The family includes nine genera and some seven hundred species. The straplike leaves were employed in ancient and medieval medicine. Dioscorides remarks on the bitterness of the leaves, but recommends that they be drunk with wine as an antidote to snakebite; he also prescribes a draught of phyllitis for dysentery and diarrhea (De Materia medica, III.121). The fifteenth-century Herbarius Latinus advocated a decoction of A. scolopendrium, drunk for forty days, to dissolve blockages of the spleen. The fern was also said to ease gout, clear eyes, heal fresh wounds, cool fever, and remove warts and pustules. The U.C.L.A.

Ferns are a group of about 20,000 species of plants (of which about 10,000 are living) in the division Pteridophyta.[2] Unlike bryophytes, ferns have xylem and phloem, which makes them vascular plants. Most ferns belong to the Class Leptosporangiata (or Pteridopsida). This includes most of those you see in gardens and woods. The horsetails belong to another class, the Equisetopsida, which was extremely important in the Carboniferous period.[3] Only one genus survives. The other classes of fern are also quite small today. Ferns do not have waxes or special cells on their surface that keep water from evaporating. They have roots, stems, leaves. Their stems may form runners, called stolons above the ground, or rhizomes below ground. The leaves are green and large, and may bear spores on the underside. Some ferns can grow large in moist places. They can survive in more places than moss, but not so many as flowering plants. During the Carboniferous period - from 350 million years ago - ferns lived ...

The concept of the pteridosperms goes back to the late 19th century when palaeobotanists came to realise that many Carboniferous fossils resembling fern fronds had anatomical features like cycads. British palaeobotanists made the critical discovery that some of these fronds were associated with seeds, and concluded that the fronds and seeds belonged to the same plants.[3] Initially it was still thought that they were intermediate between the ferns and cycads, and especially in the English-speaking world they were referred to as seed ferns or pteridosperms. Today, most palaeobotanists regard them as being only distantly related to ferns and that these names are misleading, but the names have nevertheless stuck. Later during the 20th century, the concept of pteridosperms was expanded to include various Mesozoic groups of seed plants with fern-like fronds. Some palaeobotanists also included seed plant groups with entire leaves such as Glossopteris and its relatives, which was clearly stretching ...
The Ferns ClipArt gallery contains 178 illustrations of ferns from around the world. Ferns differ from normal plants (gymnosperms and angiosperms) by having spores instead of seeds, and are vasclar plants, differing from lycophytes by having true leaves, which are also known as megaphylls. All illustrations in the ClipArt ETC collection are line drawings. If you are looking for color photographs of ferns, please visit the ClipPix ETC website.. ...
Ferns originated about 360 million years ago is the sister group of seed plants. Despite remarkable progress in our understanding of fern phylogeny, with conflicting molecular evidences and different morphological interpretations, relationships among major fern lineages remain controversial. |br|With the aim to obtain a robust fern phylogeny, we carried large scale phylogenomic analysis using high-quality transcriptome sequencing data which covered 69 fern species from 38 families and 11 orders. Both coalescent-based and concatenation-based methods were applied to both nucleotides and amino acids sequences in species tree estimation. Among the mainly consistent and strongly supported cladograms, coalescent-based method using nucleotides sequence yielded the most robust cladogram. |br|Our result confirmed that Equisetales is sister to the rest of ferns, and Dennstaedtiaceae is sister to eupolypods. Moreover, our result strongly supported some relationships new to the current view of fern phylogeny

The cinnamon-brown fruiting stalks give this fern its name. One of the largest and most dramatic of our native ferns, Osmunda cinnamomea looks best when placed in the back of the woodland garden. Unlike some large ferns, Cinnamon Fern does not spread rapidly by rhizomes. Prefers moist, neutral to acid soil, in sun or shade.
inbreeding, if not totally selfing, and thus does not ex- perience sexual recombination. The equivalence of the number of genotypes with the number of hybrid origins, therefore, appears to be a valid assumption in this species.) Alternatively, the existing populations could be remnants of a once more continuous, southern Rocky Mountain metapopulation, most of which has gone extinct. Even under the latter scenario, however, one must invoke dis- persal from a single original point of hybridization with subsequent reduction in population size.. The genetic identities among the continental U.S. pop- ulations may be particularly significant in unraveling the biogeographic history of this species in light of its tetra- ploid nature. Werth and Windham (1991) proposed a model of speciation of allopatric populations of polyploid pteridophytes involving reciprocal silencing of alternate alleles at homoeologous loci, and several empirical studies have documented such reciprocal silencing in disjunct, ...
November 13, 2019 , 5 minute read Giant salvinia is an invasive floating fern from Brazil. The plant spreads vegetatively, from whole plants or plant fragments. Giant salvinia can double its surface acreage in less than one week. It has been spreading and causing problems in coastal Louisiana since 1989. Giant salvinia tends to accumulate in small ponds or areas lacking water exchange. Once it covers the waters surface, this floating plant will begin to stack up upon itself, and can extend 12 inches or more above the water surface. Learn more.... ...
Lady Fern (Athyrium filix-femina) is widely adaptable and fast growing classic beauty. Creeping by rootstocks, it is perfect for planting on wooded slopes to help stabilize the soil and prevent erosion. Plant in masses by itself, or mix with other woodland wildflowers and sedges. Best grown in rich, medium moisture, it does tolerate drier soils than many other ferns. Shelter from wind to protect fronds from breaking.

We analyzed nucleotide variation in rbcL (the gene encoding the large subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase) from 99 genera of leptosporangiate ferns representing 31 of the 33 extant families. Phylogenetic relationships were inferred using three methods: neighbor joining, maximum parsimony, and maximum likelihood. All three methods resulted in optimal trees that were similar. Within the context of those taxa examined, these trees suggest that: 1) Polypodiaceae, Grammitidaceae and Pleurosoriopsis form a monophyletic group that is most derived among indusiate ferns; 2) Davallia is closely related to the Polypodiaceae; 3) Tectaria is related to Oleandraceae rather than to other members of Dryopteridaceae; 4) Rumohra and Elaphoglossum are closely related; 5) Dryopteridaceae are polyphyletic; 6) a monophyletic group consists of Polypodiaceae, Grammitidaceae, Davalliaceae, Oleandraceae, Nephrolepidaceae, Lomariopsidaceae, Dryopteridaceae, Thelypteridaceae, Blechnaceae, Aspleniaceae, and
As the sister lineage to seed plants, ferns represent a critical clade for comparative evolutionary studies in land plants [1, 2]. In contrast to seed plants, ferns typically retain the ancestral condition for a suite of life history traits (e.g. the lack of secondary growth, homospory, motile sperm, and independent free-living gametophyte and sporophyte generations). Ferns are thus an important outgroup for studying the evolution of wood, seeds, pollen, flowers, and fruit among other economically important characteristics found in seed plants, as well as the evolution of development in these complex structures and the expansion of gene families associated with seed plant evolution (e.g. transcription associated proteins). For reasons not yet fully understood, ferns typically have much higher chromosome numbers and larger genomes than seed plants [1, 3, 4].. Understanding the factors that influence these differences and their evolutionary consequences will require developing genomic resources in ...

Dryopteris erythrosora (Autumn Fern, Japanese Shield Fern) - 10 images at image, phylogeny, nomenclature for Dryopteris erythrosora
FERN was formed in response to the anthrax attacks that followed 9/11. It was then and is now a network of local, state and federal laboratories which contributes testing capability and capacity, relieving the burden to other agencies that also test food samples. Over time, the mission of FERN has broadened to include food safety and public health emergency and outbreak testing. Because food could be contaminated, intentionally or not, by many types of agents, there are FERN microbiology, chemical, and radiation laboratories. Wadsworth Center is home to all three.
The fern is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction. Like the Sierpinski triangle, the Barnsley fern shows how graphically beautiful structures can be built from repetitive uses of mathematical formulas with computers. Barnsleys 1988 book Fractals Everywhere is based on the course which he taught for undergraduate and graduate students in the School of Mathematics, Georgia Institute of Technology, called Fractal Geometry. After publishing the book, a second course was developed, called Fractal Measure Theory.[1] Barnsleys work has been a source of inspiration to graphic artists attempting to imitate nature with mathematical models.. The fern code developed by Barnsley is an example of an iterated function system (IFS) to create a fractal. This follows from the collage theorem. He has used fractals to model a diverse range of phenomena in science and technology, but most specifically ...

Background and Aims. Projections of cell wall material into the intercellular spaces between parenchymatic cells have been observed since the mid-19th century. Histochemical staining suggested that these intercellular protuberances are probably pectic in nature, but uncertainties about their origin, composition and biological function(s) have remained.. Methods. Using electron and light microscopy, including immunohistochemical methods, the structure and the presence of some major cell wall macromolecules in the intercellular pectic protuberances (IPPs) of the cortical parenchyma have been studied in a specimen of the Asplenium aethiopicum complex.. Key Results. IPPs contained pectic homogalacturonan, but no evidence for pectic rhamnogalacturonan-I or xylogalacturonan epitopes was obtained. Arabinogalactan-proteins and xylan were not detected in cell walls, middle lamellae or IPPs of the cortical parenchyma, whereas xyloglucan was only found in its cell walls. Extensin (hydroxyproline-rich ...
Those of you who have been following the blog this week know where Im going. (The heading just above kind of gives it away as well, I guess.) So, in answer to the burning question, Are there any plants that will remediate soils contaminated with arsenic? the answer is, Yes! In fact several.. The one used on industrial sites, the one youll see over and over (and over) if you Google arsenic phytoextraction, is Chinese brake fern (Pteris vittata L.), a.k.a. Chinese ladder brake fern, ladder brake fern, or just brake fern. Brake ferns are perfect for phytoremediation: they grow quickly, theyre easy to care for, and unlike many ferns, they tolerate a wide range of light conditions, from full sun to partial shade. And they seem oblivious to arsenic: a plant doesnt even qualify as a hyperaccumulator unless it absorbs at least 100 times as much of a toxin as can normal plants, and Chinese brake fern can absorb up to 200 times as much without any signs of phytotoxicity (plant ill-health.)

It has a stout, woody, creeping or ascending stock with large, green lacy fronds typically 10-60 cm (4-24 in) and rarely 90 cm (35 in) long. The deltate[2] fronds are bipinnate at the base, pinnate toward the apex. The rhizome is erect or ascending, often producing offshoots. Sori occur medially on the underside of the pinnae. Propagation is by spores and vegetatively by division of the rhizome. It is easily confused with the related Dryopteris dilatata (broad buckler fern), differing in the usually smaller fronds, and in the pale brown scales on the frond stem being more uniform in color, rarely having a dark central stripe. It also differs in cytology in having 2n = 82 chromosomes (164 in D. dilatata). Leaves of D. expansa are very similar to those of D. arguta.[3] The species name of this fern, expansa, is from the Latin expando, meaning to spread out, spread apart, to expand. Other common names include northern wood fern, arching wood fern, spiny wood fern and crested wood fern. ...

Occurrence. Adiantum is a common fern. It is found in the plains of the Punjab. It grows in shady places. It is found on moist walls or rocky places. The common specie of this genus is Adiantum Capillus-Veneris.. General structure. The vegetative plant body is a sporophyte. It is differentiated into stem, leaves and roots.. 1. Rhizome: The stem is underground rhizome. Rhizome is closely covered by scales called palea. The older parts of the rhizome boar numerous bases of the old leaves. Rhizome develops numerous branched adventitious roots.. 2. Leaves:. Adiantum has large bipinnately compound leaves. The main axis of the leaf is called the radius. The leaflets of the first order are called pinnae and leaflets of the second order are called as pinnules. Each leaflet is green and triangular. It has broader end towards the apex. The broader end is divided into three or four small lobes. These lobes are reflexed back. These reflexed apical lobes bear the sporangia on their underside. The young ...

The Mountain Laurels are at their peak this week as are the later native Azaleas and Rhododendrons. Though we have flirted with drying out the last week or so, theres been adequate moisture all spring and most of last year. Among the many plants that have responded well are the Ferns of Fern Valley. Cinnamon and Ostrich Ferns are well known for their ability to achieve fairly spectacular sizes when growing in constantly moist conditions, but most ferns seem to have the ability to get a little bigger in seasons where they have more water than ususal. This is one of those seasons. Combining this moisture with the sporadic short hot spells weve experienced this spring and we have a lot of big healthy ferns. Worth a look ...
The ultrastructural details of fertilization in the fern Marsilea vestita, including gamete approach and fusion, the fate of the spermatozoid organelles and the development of a possible block to polyspermy are described. The spermatozoid approaches the egg through layers of mucilage that surround the megaspores. It moves down the neck of the archegonium into the cavity above the egg. In order to reach the egg, it must move through a small hole in the thick wall that lies across the top of the egg. The fusion of the plasma membranes of the gametes results in an outflow of egg cytoplasm into the clear space under the sperm plasma membrane, creating a fertilization cone. All the organelles of the fertilizing spermatozoid, including nucleus, mitochondrion, microtubule ribbon, multilayered structure, and flagellar band, with approximately 150 flagella, enter the egg cytoplasm. The nucleus enters as a condensed rod of chromatin with no nuclear envelope. The chromatin begins to disperse immediately ...

Cell membrane prevents the entrance of extra molecules (e.g., transcription and translation inhibitors) into the cell. For studying the physiological effects of transcription and translation inhibitors on Hymenophyllum caudiculatum fronds, we incubate fronds with 0.1% DMSO to test if this increases cell membrane permeability relative to incubation with ultrapure water. The study showed that DMSO could significantly improve the cell membrane permeability of filmy fronds.

Characteristics of Divisions Division Bryophyta - (9,500 sp.) - mosses, Mnium, Sphagnum Mosses come in two basic types, a cushiony type, with erect stalks, and a feathery type, which forms flattened mats of low-lying and highly branched moss plants. In both cases, the leafy green gametophytes are dioecious They can be male plants, with antheridia at the top of the plant, or female plants, with archegonia at the top. Remember that these gametophytes are always haploid (1N) plants. Sperm are produced within each antheridium, and an egg in each archegonium. Because the plant is already haploid, these gametes can be created by mitosis, simple cell division. The sperm swims to the archegonia through a thin film of water, drawn by a chemical attractant produced by the female plant, then swims down the neck of the archegonia to the egg.

Azolla is a highly productive plant. It doubles its biomass in 1.9 days or more,[9] depending on conditions, and yield can reach 8-10 tonnes fresh matter/ha in Asian rice fields. 37.8 t fresh weight/ha (2.78 t DM/ha dry weight) has been reported for Azolla pinnata in India (Hasan et al., 2009).[10]. Azolla filiculoides (red azolla) is the only member of this genus and of the family Azollaceae in Tasmania. It is a very common native aquatic plant in Tasmania. It is particularly common on farm dams and other still water bodies. The plants are small (usually only a few cm across) and float, but can be very abundant and form large mats. The plants are typically red, and have very small water repellent leaves. Azolla floats on the surface of water by means of numerous small, closely overlapping scale-like leaves, with their roots hanging in the water. They form a symbiotic relationship with the cyanobacterium Anabaena azollae, which fixes atmospheric nitrogen, giving the plant access to the essential ...
These are some of the earliest known rainforests to evolve on our planet, he said. It was like something out of Jules Verne.. Giant tree ferns would have formed a lower canopy 30 feet high. Poking up through the ferns would have been 100-foot-tall clubmosses asparagus-like poles that sprouted crowns full of spores. It was the age of insects, with 6-foot-long millipedes and dragonflies with yard-long wingspans.. Imagine these forests alive with chirping and all these creepy crawlers, Falcon-Lang said. Trees stuck in time. An earthquake preserved all this for posterity. Elrick says it was akin to the 1811-12 earthquakes near New Madrid, Mo., which dropped a block of earth containing the Mississippi River, creating a natural dam that made Reelfoot Lake in Tennessee.. When the ancient earthquake hit, a sudden flooding in the submerged block killed the rainforest. Mud and silt rushed into the depression, preserving the stumps and logs in a layer that eventually became shale.. And that was the ...
From the Greek pteron = wing, from the wing-like shape of Pteris fronds. A genus of around 250 species from tropical and subtropical regions. Mostly grown as houseplants but a few may be suitable for out-door planting in mild areas. They tolerate dryer air conditions so make good houseplants. A great way of using these ferns is to grow in containers and plunge outdoors in summer and bring in overwinter.

New Orleans Railways tried to maintain those separate agreements, but labor representatives insisted on one agreement for the entire company.

The union struck on September 27, 1902. After about two weeks of strife, a settlement was reached, and in early 1903, the company signed a contract and recognized the union.[21] In 1902, there were protests when the Louisiana legislature mandated that public transportation must enforce racial segregation.
