Scirpus Tuberosus
''Scirpus'' is a genus of grass-like species in the sedge family Cyperaceae many with the common names club-rush, wood club-rush or bulrush (see also bulrush for other plant genera so-named). They mostly inhabit wetlands and damp locations. Taxonomy The taxonomy of the genus is complex, and under review by botanists. Recent studies by Taxonomy (biology), taxonomists of the Cyperaceae have resulted in the creation of several new genera, including the genera ''Schoenoplectus'' and ''Bolboschoenus''; others (including ''Blysmus'', ''Isolepis'', ''Nomochloa'', and ''Scirpoides'') have also been used. At one point this genus held almost 300 species, but many of the species once assigned to it have now been reassigned, and it now holds an estimated 120 species. Description ''Scirpus'' are rhizomatous perennial herbs, with 3-angled stems and flat grass-like leaves. The flowers are in clusters of small spikelets, often brown or greenish brown. Some species (e.g. ''S. lacustris'') can rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scirpus Atrovirens
''Scirpus atrovirens'', known as dark-green bulrush, is a perennial sedge native to wetlands of eastern Canada and the United States. It is sometimes called dark green bulsedge, black bulrush, or green bulrush. It was first formally named by Carl Ludwig Willdenow in 1809. ''Scirpus atrovirens'' grows in a wide variety of wetland habitats, typically in sunny areas rather than shady. It can be found in wet meadows and shrubby thickets, openings in swamps, marshes, shorelines, as well as roadside ditches. The plant can grow up to five feet tall, and thrives in hardiness zones A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most wide ... 3–9. It is closely related to '' Scirpus hattorianus'' and '' Scirpus georgianus'', with mature fruits necessary for accurate identification. References ...
