Scirpus Polyphyllus
''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 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 reach a height of 3 m, ... [...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 Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was a ... 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 3–9. It is closely related to '' Scirpus hattorianus'' and '' Scirpus georgianus'', with mature fruits necessary for accurate identification. References ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Scirpus Diffusus
''Scirpus diffusus'' is a species of flowering plant in the sedge family known by the common name umbrella bulrush. It is endemic to California, where it can be found in several of the high mountain ranges from the Klamath Mountains to the Sierra Nevada. It grows in wetland habitat and other moist areas, such as mountain meadows. It is similar to '' Scirpus congdonii'' and was described from herbarium specimens once mislabeled as such.Schuyler, A. E. (1966). A new species of ''Scirpus'' in California. ''Brittonia'' 18:2 140-142. It is a perennial herb forming a clump of erect stems growing up to a meter tall, solitary stems sometimes occurring as well. The stems are three-angled and narrow at the middle. Sheathing leaves occur at the stem bases as well as higher up the stems. The inflorescence An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches.

Scirpus Congdonii ''Scirpus congdonii'' is a species of flowering plant in the sedge family known by the common name Congdon's bulrush after noted Californian botanist J.W. Congdon. It is native to the mountains and plateaus of far northern California and adjacent sections of southern Oregon and western Nevada. It can be found in wetland habitat and other moist areas, such as mountain meadows and waterways. It is a perennial herb forming a loose or dense clump of erect stems growing up to half a meter tall, solitary stems sometimes occurring as well. The stems are three-angled and narrow at the middle. Sheathing leaves occur at the stem bases as well as higher up the stems. The inflorescence An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches.
