Description Plants cespitose with short rhizomes; roots pale brown; fertile culms (6-) 15–60 (–75) cm tall, ± stiffly erect, trigonous, smooth or sparsely antrorsely scabrous below inflorescence, with glabrous to sparsely pilose, strongly reddish purple and sometimes sparingly fibrillose bladeless basal sheaths. Leaves 6–10, all but the upper 1–2 basal; blades 8–35 cm long, 1.6–5.2 cm wide, plicate, sparsely pilose adaxially above ligule and abaxially, the margins smooth proximally, finely antrorsely scabrous distally, the widest leaves 2.3–5.2 mm wide; leaf sheaths (0.7–) 4.2–9.5 cm long, ± glabrous to pilose, the lowermost strongly reddish purple tinged near base; inner band of sheaths stramineous to pale brown, pilose, especially on lower sheaths, to glabrous, ± red-dotted, the apex shallowly concave, slightly thickened, often finely short-ciliate; ligules 1.8–5.6 mm long, rounded to acute, the free portion stramineous to pale brown, often sparsely ciliate with long hairs. Vegetative shoots ca. 15–28 cm tall; leaves 7–9, ± similar to those of fertile culms; pseudoculms 2.5–6.5 cm long. Inflorescences 1.2–6.5 cm long, with the spikes usually all strongly overlapping, the lowest two (0.2–) 1.3 (–2.9) cm distant; spikes single at nodes, erect to ascending, with the upper sessile and the lower on stiff, ± smooth peduncles 0.6–9.5 mm long; lowermost bracts with blades (0.5–) 1.6–9 cm long, (0.3–) 0.7–2.4 mm wide, sheathless, the upper bracts much reduced. Spikes 3–5, the terminal gynaecandrous, the lateral pistillate. Terminal spikes 8–20.5 mm long; staminate portion 3–10.5 mm long, 0.8–1.6 mm wide, ca. 4–20-flowered; pistillate portion 5–13 mm long, 3–5.2 mm wide, ca. 8–60-flowered; peduncles 1.5–3.8 mm long. Lateral spikes 4–21 mm long, 3.5–5 mm wide, ca. 8–75-flowered, occasionally with a small secondary spike up to 5 mm long at base. Pistillate scales 1.4–2.7 (–3.9) mm long, 0.9–1.3 mm wide, obovate, acute to acuminate-awned, with an awn up to 0.9 (–2.4) mm long, the upper margins ± finely ciliate, hyaline with a green center, 3-nerved. Staminate scales 2–3 mm long, 1–1.4 mm wide, narrowly obovate, obtuse to acuminate, the upper margins ciliate, hyaline with a green center, 3-nerved. Perigynia 1.9–2.6 mm long, 0.9–1.4 mm wide, appressed-ascending, trigonous with ± flat, rhombic-elliptic faces, green, sparsely pilose at least in the distal two-thirds, strongly red-dotted, essentially sessile, 2–5-nerved, tapering to a ± incurved, truncate, hyaline orifice. Achenes 1.4–2 mm long, 0.8–1.1 mm wide, trigonous with ± flat to slightly concave, elliptic to obovate sides, ± loosely enveloped by the perigynia, stamineous to pale brown with ± blunt yellowish angles, ± sessile. Styles withering; stigmas 3. Anthers 3, ca. 0.9–1.1 mm long. [details]

[details]Ecology Known only from the coastal range of northern Venezuela, where it occurs from 2000 to 2300 m in moist sites in areas dominated by low shrubs and grasses (subparamo vegetation). Specimens in ripe fruit have been collected essentially throughout the year. [details]
