| 備註: Carex bodinieri Franch. FOHK: Rhizome short and woody. Culms tufted or loosely tufted, rather slender, 35–60 cm tall, trigonous, smooth. Leaves basal, shorter than culm, 1.7–2.8 mm wide, flat, rather stiff, scabrous on both surfaces and margins; sheaths short, usually splitting to base into fibers. Bracts sheathed, sheaths 1.0–3.0 cm, the lower bracts leafy, upper blades reduced to bristle-like. Inflorescence a diffuse and loose compound raceme, lower bracts bear 2(–3) branches, among them usually 1 is compound, with several 2 or more spikes; middle and upper bracts each with 1(–2) spikes, very rarely more; bracts and branches loosely distributed, the lower branches can be up to 10 cm apart, the upper branches closer to each other. Spikes many, androgynous, cylindrical to narrow-lanceolate, 1–2.5 cm, male part range from less than 1/4 of the length for lower spike to nearly 1/2 for the upper spikes, female spikelets 9–12, rather loosely distributed on spikes, peduncle slender and extend out of the sheath by up to 4 cm. Male glume narrowly ovate, 3–6 mm, apex acute, yellowbrown, hyaline, with brown short lines, midrib green 1-veined. Female glumes broad-ovate, 2.8–3 mm, apex acute, muticous or rarely with short awn, membranous, yellow-brown to brown, middle with brown short lines, midrib green 3-veined. Utricle suberect, slightly longer than glume, broad-elliptic, compressed plano-convex, 3.9–4.5 mm, membranous, pale brown to reddishbrown, dorsal side with up to 9 thin veins, glabrous or with sparse hairs towards the margins, upper margins loosely hispid, upper part abruptly contracted into a medium length beak ca. 1.3 mm, base gradually contracted to a short stipe; orifice 2-toothed. Achenes tightly enveloped, ovate to broad-elliptic, compressed plano-convex, 2–2.3 × 1.3–1.6 mm, yellowish to dark brown; style base slightly thickened; stigmas 2, usually shorter than to occasionally equal to utricle. | |
