El holotypo de Carex sagei proviene de Chile central, y su nombre ha sido tratado desde hace tiempo como sinónimo de C. fuscula. Un estudio reciente indicó, sin embargo, que C. sagei is asignable a Carex sección Ceratocystis, mientras que C. fuscula pertenece a la sección Spirostachyae. Se demuestra además que C. sagei es el nombre correcto de plantas actualmente denomindas C. barrosii. Carex sagei crece en Argentina, Chile, e Islas Malvinas (Falkland Islands), donde frecuenta hábitats palustres tales como pantanos, pastizales húmedos y márgenes de lagos, desde casi el nivel del mar hasta los 850 m s.m.. Palabras clave. Carex; Cyperaceae; Ceratocystis; Sudamérica; Taxonomía.. INTRODUCTION. The genus Carex L. (Cyperaceae) is represented in austral South America with about 110 species, most of them growing in the mountains and cooler regions of the continent. The great naturalist Rodulfo A.

article{8559943, abstract = {We investigated the monophyly of Costularia (25 species), a genus of tribe Schoeneae (Cyperaceae) that illustrates a remarkable distribution pattern from southeastern Africa, over Madagascar, the Mascarenes and Seychelles, to Malesia and New Caledonia. A further species, Tetraria borneensis, has been suggested to belong to Costularia. Relationships and divergence times were inferred using an existing four marker phylogeny of Cyperaceae tribe Schoeneae expanded with newly generated sequence data mainly for Costularia s.l. species. Phylogenetic reconstruction was executed using Bayesian inference and maximum likelihood approaches. Divergence times were estimated using a relaxed molecular clock model, calibrated with fossil data. Based on our results, Tetraria borneensis is not related to the species of Costularia. Costularia s.l. is composed of four distinct evolutionary lineages. Two lineages, one including the type species, are part of the Oreobolus clade, i.e. a ...
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges, which superficially resemble the closely related rushes and the more distantly related grasses. The family is large, with some 5,500 known species described in about 90 genera,[2][3] the largest being the true sedges genus Carex[4][5] with over 2,000 species.[6] These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands. ...

II. Classification. - Gramineae are sharply defined from all other plants, and there are no genera as to which it is possible to feel a doubt whether they should be referred to it or not. The only family closely allied is Cyperaceae, and the points of difference between the two may be here brought together. The FIG. 1 6.. Fruit ofSporo- bolus, showing the dehiscent pericarp and seed.. best distinctions are found in the position of the embryo in relation to the endosperm - lateral in grasses, basal in Cyperaceae - and in the possession by Gramineae of the 2-nerved palea below each flower. Less absolute characters, but generally trustworthy and more easily observed, are the feathery stigmas, the always distichous arrangement of the glumes, the usual absence of more general bracts in the inflorescence, the split leaf-sheaths, and the hollow, cylindrical, jointed culms - some .or all of which are wanting in all Cyperaceae. The same characters will distinguish grasses from the other glumiferous ...
Ecotypic differentiation in the tussock‐forming sedge Eriophorum vaginatum has led to the development of populations that are locally adapted to climate in Alaskas moist tussock tundra. As a foundation species, E. vaginatum plays a central role in providing topographic and microclimatic variation essential to these ecosystems, but a changing climate could diminish the importance of this species. As Arctic temperatures have increased, there is evidence of adaptational lag in E. vaginatum, as locally adapted ecotypes now exhibit reduced population growth rates. Whether there is a physiological underpinning to adaptational lag is unknown. Accordingly, this possibility was investigated in reciprocal transplant gardens. Tussocks of E. vaginatum from sites separated by ~1° latitude (Coldfoot: 67°15′N, Toolik Lake: 68°37′, Sagwon: 69°25′) were transplanted into the Toolik Lake and Sagwon sites and exposed to either an ambient or an experimental warming treatment. Five tussocks pertreatment ...

A sedge is a grass-like plant (graminoid) in the sedge family (Cyperaceae). Most would look down the sedges while walking through the woods or a wetland and just think they are grasses. While they fill much the same ecological role as the true grasses (Poaceae/Gramineae) they are botanically unique.. One thing that most people learn about sedges is the saying sedges have edges This refers to the triangular shaped stems of many of the sedge species. If you roll the base of the majority of the sedge species, particularly the Carex and Cyperus, between your fingers you feel the edges plainly. If you were to cut the stem in cross-section you would notice the triangular shape.. There are many exceptions to the rule. Most importantly there are other plants like Common Bur reed, and Sweet Flag have triangular stems that are not in the sedge family. Then there are those species like softstem bulrush that have perfectly round stems. Beware the sedges have edges saying.. ...

Question: What is the impact of the fire cues smoke and ash on seed germination of important functional groups in the heathland system, namely ericads, herbs and graminoids? We predict that if germination from heathland seed banks is in part regulated by fire cues, there should be stronger responses to fire cue treatments in seed bank samples taken from heath that has not been recently burned in comparison with samples taken from newly burned heath, where seed banks have been exposed to the same cues in situ. Location: Lygra, Lindås commune,western Norway. Methods: The efficacy of smoke, charred wood, ash and heat in promoting germination has been documented in a wide range of species and systems, but relatively little work has been done on fire-related cues in northern European heathlands under anthropogenic fire regimes. We studied fire experimentally by testing the effects of aqueous smoke solution, ash and a combination of the two treatments, on the germination of graminoids, herbs and ...
Monocots, or monocotyledons, are a class of the flowering plants, or angiosperms. Monocots are named for and recognized by the single cotyledon , or seed leaf, within the seed. The first green blade emerging from the seed upon germination is the cotyledon, which contains sugars and other nutrients for growth until the leaf is able to photosynthesize. Monocots comprise about 67,000 species, or one-quarter of all flowering plants. They include not only the very large grass family (Poaceae, 9,000 species), but also the orchid family (Orchidaceae, 20,000 species), and the sedge family (Cyperaceae, 5,000 species), as well as palms, lilies, bromeliads (including pineapple), and the Araceae, which includes skunk cabbage and philodendron. The angiosperms have traditionally been divided into monocots and dicots alone, but recent work has shown that while monocots form a natural evolutionary group, dicots do not, and so the angiosperms are now grouped into monocots, eudicots , and basal angiosperms.

Existing biozonation schemes for the Niger Delta are mainly qualitative with zonal intervals too large to record subtle events. This has made it necessary to look for additional palynological events to enable recognition of shorter, more refined interval zones to improve stratigraphical definition. Hitherto unrecognised occurrence trends of palynomorphs were discovered and used to construct a new zonation scheme that can be applied in the offshore delta area. Late Miocene to Early Pleistocene sediments have been divided into five principal assemblage zones: FF1, Anthoceros abundance zone; FF2, Elaeis guineensis-Echiperiporites icacinoides zone; FF3, Lycopodium-Retibrevitricolporites obodoensis/protrudens zone; FF4, Cyperaceae abundance zone; and FF5, Echitriletes pliocenicus-Podocarpus milanjianus zone. The zones are further subdivided into 16 sub-zones based on quantitative events with some having finer subdivisions into (a) and (b). Examples of the zonations applied to three exploration wells ...

Soil cores of 5cm diameter and 20cm depth were taken at approximately 2 week intervals during the 2001 growing season. Three age classes of Eriophorum vaginatum roots (gray (senesced), brown (suberized) and white (active)) were extracted from the cores. Following extraction, cores were cut into 5 4cm sections and sorted for roots within 1 week of extraction. Prior to processing, cores were refrigerated at ~5(C. Some root samples were unwashed, then dried at 70(C for 48 hours prior to coupled combustion/reduction and gas chromatography analysis (CHN-1000, LECO Corporation). Additional samples were washed, and some unwashed, then analyzed using the soil-corrected method (Hunt et al., 1999). Unwashed roots were presumed to retain nutrient characteristics of the rhizoplane. Soil-corrected washed and unwashed root analysis was presumed to estimate nutrient concentrations specifically in the roots, provided a check upon the potential error associated with different degrees of washing and allow for ...

The central spikelet of each pseudo-umbellet is nearly sessile, while the remaining spikelets have pedicels that are 1-3 times their length. The spikelets are about 5-9 mm. long and about one-third as wide; they are oblongoid-ellipsoid to oblongoid-lanceoloid in shape. During the blooming period, the spikelets are light greenish brown in appearance, but they later become reddish brown to brown and somewhat bristly in appearance because of the dried-out styles of the florets. Each spikelet consists of a dense head of florets and their outer scales; these scales are arranged together in several overlapping series. Individual scales are about 2 mm. in length, lanceolate to ovate in shape, and hairless; they have broad central veins that are green. Each floret has 3 stamens, a tripartite style, and an ovary. The blooming period occurs during the summer, lasting 1-2 weeks. Cross-pollination of the florets is by wind. Afterwards, the florets are replaced by achenes (one achene per floret). These ...

Carex buekii is a tall sedge, forming large stands in wetlands, particularly in river floodplains across Central Europe and thus on many sites determining the typical appearance of riverine habitats. Our paper aims at increasing the knowledge on ecology of C. buekii and its role in the wetlands. Field data were collected in Poland, the Czech Republic, Slovakia, Hungary, and Italy. Carex buekii usually occurs in nutrient rich habitats, but is also capable of colonising relatively nutrient-poor ones; it grows on both acidic and alkaline soils (pH 3.3-7.4) with diverse concentrations of assimilable elements (Ca, Mg, P, K). One of the most important ecological characteristics of C. buekii is its relationship to the floodplains of watercourses. It seems to be dependent on, or at least very tolerant to regular disturbances by streaming, floods and transport of sediments.

It flowers at 40-50 days after germination and ripens 1 month after flowering. S. juncoides produces seed, 2.0-2.3 mm long, 1.6-1.7 mm wide and 0.8-0.9 mm thick. This weed is very difficult to distinguish from Eleocharis kuroguwai at the vegetative stage. Leaves have very short blades. The stem is flattened at the base, strongly angled at the top. This weed reproduces by seeds. Seeds normally germinate at 25-35 °C with a germination of 10-25%. Seeds readily germinates at 1 cm water depth on 1-1.5 cm soil depth but there is no appreciable germination 3-5 cm soil depth. Seed dormancy is broken by low temperature under moist conditions, it also require light for germination. A common plant in lowland rice in North America, Asia, Southern Africa and some Mediterranean countries.. Stale seedbed is on of the ...
Recently a list of wetland plants in Southern Africa has been completed by Glen (2010), but there is no field guide available for the layman or student on the wetland plants of South Africa. The number of plants associated with wetlands in South Africa is such that all could not be published in one book. This lead to this field guide, that primarily includes obligate wetland plants as outlined in the caption of this book, with special focus on all grass-like plants. The plant families included are all monocotyledons and include the Cyperaceae (sedges), Eriocaulaceae (eriocaulons), Juncaceae (rushes), Poaceae (grasses), Prioniaceae (palmiet), Restionaceae (restios), Typhaceae (bulrushes) and the Xiridaceae (yellow-eyed grasses).South Africa is known to be a water scarce country. This Guide is by no means complete, but is the first in addressing some of the grass-like plants that may be encountered in a wetland. This includes the grasses, reeds, restios, sedges, rushes, bulrushes, eriocaulons and ...

This plant community is somewhat drier than the sedge meadow, and the major difference between them is that while there are often many sedges, the dominant plants are members of the grass family (Poaceae). Like sedge meadows, a major problem for wet meadows are invasive species like reed canarygrass, which may prefer the slightly drier wet meadows. However one of the most common native residents of wet meadows in the Midwest is Canada Bluejoint grass (Calamagrostis canadensis). Some consider the wet meadow to be a disturbed habitat.. Like sedge meadows, wet meadows are under threat from invasive species, especially Reed Canarygrass which has replaced many native plants with its monotypic stands. Fire suppression, and the absence of other conservation practices that control naturally invading shrubs and trees, leads to loss of this. ...

Abstract. Elevated nitrogen (N) deposition changes the retention, transformation, and fluxes of N in ombrotrophic peatlands. To evaluate such effects we applied a 15N tracer (NH4 15NO3) at a rate of 2.3 g N m−2 yr−1 to mesocosms of five European peatlands with differing long-term N deposition rates for a period of 76 days of dry and 90 days of wet conditions. We determined background N content and moss length growth, and recovered the 15N tracer from the mosses, graminoids, shrubs, the peat, and dissolved N. Background N contents in Sphagnum mosses increased from 5.5 (Degerö Stormyr, deposition , 0.2 g N m−2 yr−1) up to 12.2 mg g−1 (Frölichshaier Sattelmoor, 4.7-6.0 g N m−2 yr−1). In peat from Degerö, nitrate and ammonium concentrations were below 3 mg L−1, whereas up to 30 (nitrate) and 11 mg L−1 (ammonium) was found in peat from Frölichshaier Sattelmoor. Sphagnum mosses (down to 5 cm below surface) generally intercepted large amounts of 15N (0.2-0.35 mg g−1) and ...
To say Friday was a compelling day at The Players Championship is to say that the alligators popping up around the famed No. 17 island green enjoyed the tasty frogs, heat and water. [...] the fun may just be beginning. By the time unknown John Merrick threaded home a 13-foot birdie putt in deepening shadows on the 18th green, knocking 15 players off the cut line, the tournament had seen near-record scoring, Tiger Woods slicing a drive so badly it left spectators ducking and gasping, and an unruly, drunken fan Tasered. When Merricks final putt dropped, 70 players had survived for weekend play, taking aim at a TPC Sawgrass course as accommodating as it has been for more than 15 years. With winds beginning to swirl later in the day, TPC Sawgrass began to show its teeth, hinting the finish may be far tougher than the start. Westwood, with three straight birdies to start his back nine, has a one-shot lead over Italys Francesco Molinari, Heath Slocum and Ryuji Imada.

Assessment of emergent vegetation biomass can be time consuming and labor intensive. To establish a less onerous, yet accurate method, for determining emergent plant biomass than by direct measurements we collected vegetation data over a six-year period and modeled biomass using easily obtained variables: culm (stem) diameter, culm height and culm density. From 1998 through 2005, we collected emergent vegetation samples (Schoenoplectus californicus andSchoenoplectus acutus) at a constructed treatment wetland in San Jacinto, California during spring and fall. Various statistical models were run on the data to determine the strongest relationships. We found that the nonlinear relationship: CB=β0DH|span id=MathJax-Span-20...

The development of the specialized cells that make up the female reproductive unit in flowering plants, the gametophyte, requires the hormone auxin. However, auxins function is unknown, and its movements to and within these cells are unclear. Pagnussat et al. (see the Perspective by Friedman) provide evidence that auxin is synthesized at specific positions within the female gametophyte and exerts a positional effect and that a gradient of auxin controls patterning of these specialized cells..

And heres the stump and empty swath of lawn - the only lawn that was left in our entire yard - right after the tree came down. It happened in December, and I immediately started worrying about the Japanese maple and foundation shrubs, which would now receive a lot more sun in summer, although the north-facing house does give them some protection. I also knew that last bit of lawn had to go. Id only kept it because it was chock-full of oak sprouts, which are easier to mow than remove by hand from a planting bed, and I hoped that once we ground out the stump, the sprouts would wither away (sadly that has not been the case).. ...
Mike said Im finding that sedges are getting in the way of flat-out Viola work - Ive never had so many to determine! Dont know why. I do enjoy looking at sedges for determination - Im certainly not moaning at receiving so many specimens and being asked to comment on them, far from it, but, especially when there is the possibility of hybridity, it can be very time-consuming. I do tend to get engrossed, to the detriment of other responsibilities - both botanical and domestic! ...
