Classifications International Patent Classification A01H 5/00 United States Patent Classification PLT/373000000. Pistillate scales cuspidate, acute, or acuminate; plants not cespitose. Spikes lax, at least proximally, with not more than 15 perigynia; perigynia not inflated, not glossy, usually 2–4 times as long as wide. In some species, such as C. sprengelii, the veins in the sheaths are heavily sclerified and persist as fibrous tufts at the base of the plant and along the rhizome after the leaves decay. 1. Ovales, and in sections Carex and Holarrhenae, those stems are strictly annual. 1 Distribution; 2 Discussion; 3 Selected References; 4 Lower Taxa; 5 Keys. Subgenera are not recognized; although it is possible to assign the multi-spiked sections to subgenera, relationships of a number of unispicate sections are very unclear. Perigynia not more than 10 mm; staminate spikes 1–5(–7). Primocarex to other subgenera of Carex and Uncinia, although without making the necessary nomenclatural changes. Most species are from wet areas such as bogs or damp woods. Perigynium beak 0.9–1.7 mm; mature perigynia dull. Perigynia distinctly 12–30-veined; beak not more than 0.5 mm. scabrata from ma and nh were based on collections of C. gynandra (specimens at GH! 5.1 Key to sections of Carex; 5.2 Key A. Spike 1 per culm, all flowers attached to main stem in terminal spike. Perigynia 1.7–4 mm; culms rough distally. True vegetative stems are characteristic of Carex sect. Eucarex), the spikes were most frequently unisexual, the terminal and sometimes some distal lateral spikes being staminate, and the lateral or proximal lateral spikes pistillate; bisexual spikes occurred occasionally. 3. Pistillate spikes cylindric, much longer than wide; staminate spikes (1–)2–6. Some of these species have recently become locally naturalized (e.g., Carex pendula); the frequency of naturalization is likely to increase. Numerous interspecific hybrids have been reported in Carex, though few have been produced experimentally. Spikes gynecandrous; beak of perigyium with apical teeth 0.3 mm or longer. Returnable: 30 Day Guarantee i. Pistillate scales obtuse to acuminate or with awn less than 1 mm; staminate scales not awned. Widest leaves not more than 1 mm wide; rhizomes not more than 1 mm wide, mostly without persistent scales; scales at base of culms and on rhizomes not or scarcely fibrous. Carex (subg. Inflorescence and flower structures of Carex and other genera in tribe Cariceae (Cymophyllus and Kobresia in the flora, Schoenoxiphium and Uncinia from outside the flora) are difficult to interpret; it is by no means clear whether apparently similar structures in different sections of Carex and in the other genera are homologous (A. Perigynia yellow-brown to dark brown when mature, not black-mottled. Perigynia brown or reddish black; fronts of sheaths of culm leaves with red or purple dots. x = 10. 1980. Carex, while others place it as a sister group to the whole of the tribe Cariceae. Inflorescences globose or ovoid-globose, very dense so that individual spikes are indistinguishable; spikes consistently androgynous. Culms not exceeding 60(–80) cm; pistillate spikes not more than 60 mm, with not more than 30 perigynia. Hudson, J. H. 1977. Terminal spike staminate, androgynous, or if gynecandrous, staminate flowers more numerous than pistillate; lateral spikes at least 2 times as long as wide. Easy to grow, low maintenance, cold-hardy and a compact clumping habit are qualities that make 'Evercream' a splendid edging or container plant. There will be surely one for you! 58. Perigynium beak entire, emarginate, or with 2 apical teeth not exceeding 0.2 mm. Leaves not more than 8 mm wide, blades and usually sheaths pubescent. Copyright for Volumes 24 and 25 is held by Utah State University. Apex of perigynium beak entire, emarginate, or very shallowly bidentate. Pistillate scales with margins entire, apex awnless or with short, smooth awn. Some roots with yellow-brown felty covering. Perigynia mostly not more than 2 times as long as wide, widest near middle. Shoots of sedges vary greatly in their longevity. Historic accounts of previously published classifications and phylogenetic interpretations, based primarily on morphologic and anatomic evidence, are available (T. V. Egorova 1999; A. Native Introduced Native and Introduced. Thus Mackenzie’s arrangement met many of the criticisms of Kükenthal’s arrangement, but it cannot be applied to the genus on a worldwide basis because few species of subg. Perigynia with 2 strong marginal veins, otherwise veinless or veined only proximally; leaves not septate-nodulose. Bracts of proximal nonbasal spike with well-developed sheath at least 4 mm. Beak of perigynium mostly 2 mm or longer and at least as long as body. Primocarex, and referred to these sections as “primitive” in his synopsis of the genus. [Agric.
