General Description

Plant about 8 in. high, “scarcely cæspitose” (Welwitsch). Leaf-sheaths forming a bulbous base, leafless in the specimens seen, the outer coriaceous or scarious, tapering from a broad base, smoky-brown, shining. Peduncles arising from the midst of the persistent bases of the leaves, 5 1/2–8 in. long, flexuose, subquadrangular, glabrous, green. Peduncular-sheath about 2 in. long, rather loose above and passing into a weak acuminate point. Spike 1/4 in. thick, ellipsoid or subglobose. Bracts 2–2 1/2 lin. long, 1 1/2–2 1/2 lin. broad, coriaceous, lowermost oblong, the others orbicular, very concave, obtuse or slightly apiculate, entire, but often broken and retuse at the apex, 7–9-nerved, olive-brown, paler at the margin. Lateral sepals 2 1/4–2 1/3 lin. long, scarcely 1/2 lin. broad, falcate, with very unequal sides; keel broad, minutely denticulate-scabrid (scarcely ciliolate) from about the middle to the apex, greenish-brown below, becoming crimson above. Arms of the staminodes with narrow brush-like tufts of hairs, exceeding the oblong orange-coloured anthers.
