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. Index of Medieval Medical Images??includes a realistic representation of lingua cervina, or deers tongue, from an Italian herbal dated to about 1500..

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 ...

Pteridophytes are plants with Feather like Leaves. Pteridophytes are a group of primitive land plants belongs to the Cryptogams. They are the first evolved plant group with vascular tissue system for the conduction of water and food materials. Due to the presence of vascular tissue, they are called as Vascular Cryptogams. The term Pteridophyte is derived from two words Pteron meaning feather and phyton meaning plant. Thus, Pteridophytes are the plants with Feather-like leaves. Pteridophytes occupy the intermediate position between Bryophytes and Phanerogams (seed plants). The important characteristics of Pteridophytes are summarized below:. ...

The Bishop of Ferns and Leighlin was the Ordinary of Church of Ireland diocese of Ferns and Leighlin in the Province of Dublin. The diocese comprised all of counties Wexford and Carlow and part of counties Wicklow and Laois in Republic of Ireland. The Episcopal see was a union of the bishoprics of Ferns and Leighlin which were united in 1597. Over two hundred and thirty-eight years, there were twenty-nine bishops of the united diocese. Under the Church Temporalities (Ireland) Act 1833, Ferns and Leighlin were combined with Ossory to form the united bishopric of Ossory, Ferns and Leighlin on 12 July 1835.[1][2][3]. ...

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 ...

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.

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.

Polystichum setiferum (P. angulare) might handle some direct morning sun (the earlier in the day the better) and does fine in bright dappled light all day. The more light it receives the damper the soil should be, otherwise the foliage will dry out and turn crispy. On the other hand, this fern needs a well drained soil meaning not sopping wet or saturated, especially in the winter, or it will basically rot. (In deeper shade it tolerates a fairly dry soil compared to some ferns.) All of which is to day, it would not handle noontime or afternoon sun and I would be cautions with late morning sun as well. This lighting guideline is true for any fern I can think of. I hope this helps ...

The number of genera accepted within Blechnaceae (or Blechnoideae when treated as a subfamily) has varied between authors. Christenhusz and Chase (2014), treating the group as a subfamily, describe the situation as follows: "Blechnoideae comprise three major clades, one corresponding to Onoclea sensu lato, a second corresponding to Woodwardia, sister to all other species that can be treated as the single genus Blechnum. However, the subclade sister to the rest of Blechnum sensu lato contains the vining taxa Stenochlaena, Salpichlaena J.Sm. and a few non-vining Blechnum species with long-creeping rhizomes, which may have to be accepted at the generic level pending further studies. Brainea, Doodia, Pteridoblechnum and Sadleria belong to Blechnum sensu lato."[2] Perrie et al. (2014) retained the family rank and excluded Onoclea as a separate family, Onocleaceae, sister to Blechnaceae. They identified three major clades within the remaining Blechnaceae, which they labelled Woodwardia, ...

Plants colonized the terrestrial environment over 450 million years ago. Since then, shoot architecture has evolved in response to changing environmental conditions. Our current understanding of the innovations that altered shoot morphology is underpinned by developmental studies in a number of plant groups. However, the least is known about mechanisms that operate in ferns − a key group for understanding the evolution of plant development. Using a novel combination of sector analysis, conditional probability modelling methods and histology, we show that shoots, fronds (leaves) and pinnae (leaflets) of the fern Nephrolepis exaltata all develop from single apical initial cells. Shoot initials cleave on three faces to produce a pool of cells from which individual frond apical initials are sequentially specified. Frond initials then cleave in two planes to produce a series of lateral merophyte initials that each contributes a unit of three pinnae to half of the mediolateral frond axis. ...

Spore-bearing capsules called sporangia appear on the edges or undersides of mature fronds. When they split open, the spores are released. These germinate in damp places to become tiny heart-shaped plants. When it rains, male sex cells are carried by the water towards female egg cells. The fertilised eggs grow into leafy fern plants.. Many ferns also have non-sexual or vegetative means of production. They produce buds or tiny copies of themselves, which drop to the ground and take root.. ...
