Received: September 23, 2008. Accepted: March 20, 2009. RESUMO – (Morfoanatomia do caule de algumas Cyperaceae). As especies da familia Cyperaceae sao normalmente perenes com caule subterraneo principalmente do tipo rizomas, entretanto outros tipos tambem podem ocorrer, como cormos e tuberculos.
A colonial perennial sedge 30–110 cm tall with scaly tan rhizomes 2–15 cm long by 2–4 mm thick; roots whitish tan,. 2–16 cm long by c. 1 mm wide with fine hairs 0.5–2 cm long; in swampy areas, slough margins, seeps, wet meadows and prairies, ravines, forest openings and along riverbanks. l FLOWERS Yellowish green,
The prophylls of Cyperaceae have been discussed in a full paper by. Blaser (1944),and others, particularly Holttum (1948),Koyama (1961)and. Kern (1962), have considered them in relation to spikelet structure and phylogeny. But they do not usually figure in taxonomic descriptions or drawings and are still relatively little
The basic unit of the inflorescence in most Cyperaceae is the spikelet. This com- prises a very short to elongated axis, which subtends one to many scalelike bracts, referred to here as glumes. Each glume subtends and partially hides a single very small, bisexual or unisexual flower, which may or may not have a perianth.
lThis account of the family CYPERACEAE of north-eastern India is the first consolidated account of sedges published in the current century for such a large region, spreading over more than 250,000 sq. km and covering the States of Arunachal Pradesh, AsSam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura.
A widely distributed family of herbs primarily found in warm temperate to tropical regions worldwide. Climbing herbs in the Cyperaceae are restricted to the genus Scleria and occur primarily in the Neotropics. There are 13 out of a total 116 species of Scleria in the. Neotropics that are climbing herbs. They are predominant in
The Cyperaceae are a family of monocotyledonous graminoid flowering plants known as sedges, which superficially resemble grasses and rushes. The family is large, with some 5,500 known species described in about 90 genera, the largest being the Carex genus of "true sedges" with over 2,000 species. These species

livestock and are major deterrents to agricultural and forest productivity. Most weeds are exogenous and have traits that give them biological and reproductive advantages over other plants. Weeds cost billions of dollars in agriculture, forestry, and urban areas and threaten diversity in natural communities worldwide. Of an.
Cyperaceae is a cosmopolitan family of an estimated 5000 species and 100 genera (Ball et al. 2002). Members of. Cyperaceae are commonly called sedges. Sedge weeds adversely affect agriculture and forest, urban, and natural areas throughout the world. The number of sedges considered to be weeds has increased
