Carex Reznicekii
''Carex reznicekii'', known as Reznicek's sedge, is a species of '' Carex'' native to North America. It is a perennial. Described initially from a New York population, this species was named in 2006 in honor of the botanist Anton Reznicek, a specialist in the genus ''Carex''. Description This species resembles '' Carex umbellata'' and '' Carex nigromarginata''. ''C. reznicekii'' can be readily distinguished from ''C. umbellata'' by the absence of basal spikes observable on ''C. reznicekii''. ''C. reznicekii'' most strongly resembles ''C. nigromarginata'', but can be differentiated by several factors, including ''C. reznicekii's'' narrower leaves and more-or-less uniform culm lengths. ''C. reznicekii's'' species status and distribution was determined in part through the use of herbaria records, where many instances of ''C. reznicekii'' were erroneously identified as ''C. umbellata'' and ''C. nigromarginata''.

Carex
''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial, although some species, such as '' C. bebbii'' and '' C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
