Leptocarpus similis Edgar

Rhizome 3-7 mm in diameter, closely covered by dark brown, imbricating scales, 1-2 cm long, each enclosing a tuft of coarse brown hairs, Culms 50-150-(180) cm × 1.5-2.5 mm, usually densely packed, erect, simple, terete, grey-green, yellow-green or reddish. Leaves all reduced to bract-like sheaths, dark brown, almost black, spaced at intervals of 7-9 cm at the base of the culm, and 4-6 cm higher up; margins entire. Male and female inflorescences dissimilar. Male spikelets pedunculate, in panicles or fascicles; upper floral bracts ovatelanceolate, mucronate, red-brown with membranous margins. ♂ flowers: tepals 6-4, almost completely hyaline, the outer longer, brownish, the inner shorter, paler; stamens 3; ovary rudimentary. Female spikelets ± sessile, fascicled; upper floral bracts ovate, mucronate, larger than tepals. ♀ flowers: tepals 6, the outer keeled, lanceolate, acuminate, the inner flat, smaller, almost hyaline, more obtuse, mucronate; styles 3, united to midway, bright red; staminodes 0. Fruit c. 1.0 × 0.5 mm, triquetrous, indehiscent. Seed c. 1.0 × 0.4 mm, oblong-elliptical, goldenbrown, surface with reticulate markings, apiculate at each end, one end dark brown, the other pale, almost white,
