The fruit is a three-angled achene. Young plants initially form white, fleshy rhizomes, up to 25 mm (1.0 in) in dimension, in chains. Some rhizomes grow upward in the soil, then form a bulb-like structure from which new shoots and roots grow, and from the new roots, new rhizomes grow. Other rhizomes grow horizontally or downward, and form dark ...
The Cyperaceae (/ ˌ s aɪ p ə ˈ r eɪ s i. iː,-ˌ aɪ /) are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges.The family is large; botanists have described some 5,500 known species in about 90 genera [3] [4] – the largest being the "true sedges" (genus Carex), [5] [6] with over 2,000 species.
Cyperus albostriatus (dwarf umbrella sedge), formerly called C. diffusus) [14] Cyperus haspan [15] Cyperus longus [14] [16] Cyperus papyrus (papyrus) [14] Some Cyperus species are used in folk medicine. Roots of Near East species were a component of kyphi, a medical incense of Ancient Egypt. Tubers of C. rotundus (purple nut-sedge) tubers are ...
Carex is a vast genus of over 2,000 species [2] 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.
Carex stipata, variously called the prickly sedge, awl-fruited sedge, awlfruit sedge, owlfruit sedge, swamp sedge, sawbeak sedge, stalk-grain sedge and common fox sedge, is a species of flowering plant in the genus Carex, native to Canada, the United States, China, Korea, Japan, and Far Eastern Russia. [3] [4] [5] [2] It is a wetland obligate. [6]
Sedges (Cyperus) have grass-like leaves and resemble each other in the appearance. They can mainly be distinguished from grasses by their triangular stems. Purple nutsedge (C. rotundus) is another weedy sedge that is similar to the yellow nutsedge (C. esculentus). These two sedges are difficult to distinguish from each other and can be found ...
The annual sedge typically grows to a height of 0.1 to 0.75 metres (0.3 to 2.5 ft) and has a tufted habit. It blooms between May and December and produces green-yellow-brown flowers. [3] The erect and glabrous grass has fine and numerous roots. It as slender or rigidulous, trigonous stems that are 0.5 to 2.0 millimetres (0.020 to 0.079 in) thick.
Carex molesta is a species of sedge known by the common name troublesome sedge. It is native to eastern and central North America, where it grows in varied wet and dry habitats, performs equally well in full sun and partial shade, including disturbed areas such as roadsides. It is an introduced species and often a weed in California.
