 Description

Rush-like; rhizome short, up to 3 mm. diam., with closely appressed, dark red-purple bracts. Culms 60–90 cm. long, us. slightly < 1 mm. diam., densely tufted, light green. Lvs reduced to brown, sheathing, mucronate bracts, the mucro more elongated in the uppermost bracts; mouth of sheath not ciliate. Panicle 8–15–(22) cm. long, very slender, with ± distant fascicles of 3–4 branchlets, each fascicle subtended by a short sheath similar to those at base of culm; branchlets filiform, flexuous, laterally compressed, edges not toothed, simple or branched again. Spikelets single at the tips of the branchlets, 7–10 mm. long, 2-fld, very narrow, compressed, linear-lanceolate, grey-brown. Glumes 5–7, closely imbricating, lanceolate, acute, almost entirely hyaline except near the midrib, margins not ciliate, 3–4 lower glumes and uppermost glume empty.
