Description Small, shortly rhizomatous perennial. Culms very slender, erect, smooth, finely striate,
nodeless, 4-12 cm high, 0.2-0.4 mm diam. Leaves basal, with blade to 12 (rarely
to 23) cm long, 0.3-0.4 mm wide, slender but channelled; sheath red-brown to stramineous,
striate, more or less shining, mouth glabrous; ligule present. Inflorescence consisting of
1-4 spikelets in 1 or 2 clusters, 1-4 cm long; lowest involucral bract leaf-like, to 5 cm
long. Spikelets compressed, narrow-ovate, acute, 1-2-flowered, 3.5-5.5 mm long, with
rachilla elongated and zig-zag around fertile flowers. Glumes distichous, 4-6 with
lowest 2-4 empty, narrow-ovate, acute, stramineous to red-brown, more or less shining, with
glabrous margins; fertile glumes 3.0-4.0 mm long. Bristles 6, not plumose, about as
long as nut. Stamens 3; anthers 1.5-2.0 mm long excluding the apical appendage that
is 0.3-D.5 mm long. Style 3-fid. Nut trigonous, ellipsoid, prominently 3-ribbed, minutely
reticulate, glistening or shining, whitish with hispidulous red-brown apex or evenly
red-brown, 1.2-1.4 mm long, 0.4-0.7 mm diam. [details]
