Reznicek, A. In some members of sect. Pistillate scales, at least some, with scabrous awn. Providing year-round color, Carex oshimensis 'Evercream' is a very distinctive Japanese Sedge with narrow, arching, rich green leaves adorned with creamy edges. Adaxial side of leaves with 2 marginal veins more prominent than midvein; young leaves M-shaped in cross section. In early summer, it bears inconspicuous, slender, brown flower spikes, upright at first then slightly nodding over. Terminal spike staminate, androgynous, or if gynecandrous, staminate flowers more numerous than pistillate; lateral spikes at least 2 times as long as wide. Pistillate scales obtuse to acuminate or with awn less than 1 mm; staminate scales not awned. Distal leaves of culms with front of sheaths green-veined, not differentiated from rest of sheath. Phylogenetic relationships in Cariceae (Cyperaceae) based on ITS (nrDNA) and trnT-L-F (cpDNA) region sequences: Assessment of subgeneric and sectional relationships in Carex with emphasis on section Acrocystis. Pistillate spikes, at least the proximal, lax, proximal and middle perigynia separated by internodes at least 1/4 their length; leaves and sheaths not septate-nodulose. Our effective formula with added moisturisers, removes dirt and germs and provides antibacterial protection. 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. The lateral spikes were peduncled or subsessile and bore a minute, tubular prophyll at the base of the peduncle. 68: 1405–1472. Apical teeth of perigynium beak reflexed; achenes elongate; pistillate scales with 1-veined center. Primocarex. Leaves and/or sheaths pubescent, at least at junction of blade and sheath. Carex pendula has a less reflective, dull gray-green leaf underside while Scirpus microcarpus has a very reflective, apple green leaf underside. Carex: Leaves of many species have sharp and saw-like edges. Perigynium beak entire, emarginate, or with apical teeth not more than 0.1 mm. Perigynia with 2 distinct marginal veins, otherwise veinless or only very faintly veined; leaves not septate-nodulose. Vol. Copyright for Volumes 24 and 25 is held by Utah State University. 1 Distribution; 2 Discussion; 3 Selected References; 4 Lower Taxa; 5 Keys. Perigynium beak with apical teeth (0.4–)0.6–3 mm, often longer than 1 mm. The Japanese species Carex oshimensis is a variegated form with attractive green and pale yellow foliage. Many sedges are US native plants and are easy-to-grow shade perennials for the woodland garden. Terminal spike gynecandrous or pistillate. Perigynia linear-lanceoloid, 3–4 times as long as wide; achenes 1.5–2.5 mm. Starr et al. Pistillate scales with margins serrulate distally; awn, when present, rough. Carex vaseyi Dewey Carex vesicaria alpigena Fr. Brightening up the shade garden, Carex morrowii 'Variegata' is a semi-evergreen Japanese Sedge forming a low, slow-spreading tufted mound of narrow, arching, glossy, deep green leaves adorned with fine creamy-white edges. Carex is the UKâs number 1 hand wash brand. Apex of perigynium beak entire, emarginate, or very shallowly bidentate. Perigynia pubescent; pistillate spikes ovoid with not more than 25 perigynia. Perigynia sharply trigonous in cross section. Flora Europaea. ... Classifications International Patent Classification A01H 5/00 United States Patent Classification PLT/373000000. Perigynia often papillose over most of surface; style deciduous. Spikes not consistently androgynous, terminal either entirely staminate or pistillate, lateral spikes irregularly pistillate or staminate or mixed. 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. Vignea, and then a group of sections included by Kükenthal in subgenera Primocarex, Indocarex, and Carex. Their results are probably of general application as a wide diversity of Carex sections were included. Spikes gynecandrous; beak of perigyium 0.1–0.3 mm. Perigynia ascending, spreading at about right angles, or reflexed when mature. Style deciduous; larger leaves and sheaths sometimes septate-nodulose, more often not. Species of Carex are often dominant or co-dominant in such habitats, including arctic tundra. The flora area is species rich, almost comparable to eastern Asia. Carex Health Brands has been the branded leader in in-home, self-care medical products for over 35 years. Presenting similar criticisms E. Nelmes (1952) distributed sections of subg. Style persistent on achene in fruit; larger leaves and sheaths usually at least sparsely septate-nodulose, rarely not. Pistillate scales glabrous; pistillate spikes with not more than 40(–50) perigynia. 1964–1980. Distal leaves with blades more than 2 cm, longer than sheaths. Perigynia strongly 12–30-veined; proximal bract sheaths not more than 5 mm. Species richness of native aquatic plants may be reduced by more than 50% and submerged species may even disappear entirely (Nijs et al. Perigynia at least slightly prominently veined or veinless except for 2 marginal veins. Perigynia with veins on faces, ± distinct at least over achene. Plants usually not cespitose, single-stemmed; margins and beak of perigyium only weakly and sparsely serrulate. 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. Amer. This distinction is usually clear in regions with cold winters; it may be blurred in subtropical and tropical areas. Perigynia strongly veined on both faces; beak not more than 0.6 mm, less than 1/5 length of body. The pistillate flower of Carex is believed to be derived by reduction from an inflorescence unit similar to those found in Kobresia and Schoenoxiphium, namely a branch in the axil of a scalelike bract bearing pistillate flower(s) proximally and staminate flowers distally (D. L. Smith and J. S. Faulkner 1976). Spikes 2+ per culm, some flowers in lateral spikes. Many single-spiked species, however, were associated with sections Kükenthal had included in the other subgenera. Terminal spike gynecandrous with few perigynia; stigmas 3. Carex L. (Cyperaceae) is one of the largest angiosperm genera (Reznicek 1990). Perigynia with flat, winglike margins 0.1 mm wide or wider distally; plants long-rhizomatous, not cespitose, sometimes colonial. Pistillate scales acute or shortly cuspidate, with midvein protruding from body of scale less than 0.2 mm. Reminiscent of the garden carnation foliage, Blue Sedge is a great choice for naturalizing. Perigynia smooth, sometimes with minute teeth on margins. Rachis of spikes papillose; peduncles with prophyll. Pistillate spikes spreading or pendent, mostly with peduncles longer than spikes (spikes often erect on short peduncles in arctic and high mountain dwarf plants); perigynia veinless except for 2 marginal veins or with fewer than 10 veins, not speckled red-brown. Proximal perigynia in each spike ascending or spreading-ascending; leaf blades and sheaths not septate-nodulose. Perigynia veinless or with veins only proximally; pistillate scales white-hyaline or red-brown. Spikes ± consistently androgynous, occasionally some lateral spikes entirely pistillate. Perigynium beak not more than 0.25 mm, margins entire, not serrulate. Leaf sheaths and usually blades pubescent. Pistillate scales dark brown to almost black; proximal leaf blades with marginal veins equally prominent; leaves on culms as wide as basal leaves. Fronts of leaf sheaths dotted red, brown, or yellow. Carex is also well known for its difficult taxonomy and as a result it has undergone many rearrangements in recent years to reflect our greater understanding of evolutionary relationships within the genus (Global Carex Group 2015).Despite more than 15 yr of phylogenetic investigation (e.g. Perigynia mostly more than 2 times as long as wide, widest near base. Providing year-round color, Carex oshimensis 'Everlite' is a very distinctive Japanese Sedge with narrow, arching, creamy leaves adorned with rich green edges. 2000.
