Vegetative parts: plants tufted (Large, stout tufts, or smaller at upper altitudes), 0.3–1.3 m tall, basal diameter 0.1–0.4 m, crown diameter 0.5–1 m, compact, without spreading rhizomes or stolons. Fertile culms unbranched, round (not compressed), solid or with a small central cavity, smooth, olivaceous, 0.3–1.3 m tall, diameter at base 1.5–2.5 mm, diameter at apex 1–1.5 mm. Clusters of sterile branches at the nodes of the fertile branches absent. Sheaths more than 1 per culm, dropping off, with an abscission line present, loosely convoluted, 20–35 mm long, margins entire, golden brown, upper 1/3 in colour and texture similar to the lower 2/3, apical margins coriaceous, like the rest of the body, hyaline shoulders absent, apex, excluding the membranous lobes, acute or obtuse. Sheath-mucro absent or penicellate, straight and erect, 0.5–1 mm long, Sheaths drop off at flowering. Males: male inflorescence with 11–20 spikelets or 21–50 spikelets, paniculate, 20–180 mm long, 15–25 mm wide. Male inflorescence spathes persistent, taller than spikelets (15–40mm long), chartaceous. Male spathellae inconspicuous or absent. Male flowers in spikelets. Male spikelets erect on stiff pedicels or sessile, oblong, apex obtuse, 7–20 mm, 5–10 mm, with 15–25 flowers, pedicels absent ie spikelets sessile or shorter than the spikelets, terete or angular. Male bracts taller than flowers, 10–15 mm long, linear or ovate, acuminate, margins deeply lacerated or toothed, chartaceous or membranous, bract upper margin membranous, thinner texture than the body, bract awn minute or absent, Male bracts deeply lacerated or toothed along the margins, giving the spikelets a woolly look. Male flower 4–4.5 mm long. Male tepals sepals and petals the same rigidity, cartilaginous, oblong or ovate, inner and outer tepals the same length. Male outer lateral tepals as other tepals, glabrous. Anthers 1.3–1.5 mm long, included in the flowers. Pistillode present (with 3 styles). Females: female inflorescence linear, 30–160 mm long, 15–20 mm wide, with 11–20 spikelets or 21–50 spikelets. Female spathes longer than the spikelets, not obscuring spikelet, persistent (become torn and grey with age), chartaceous. Female spathellae inconspicuous or absent. Female spikelet pedicel simple (but short), oblong or undifferentiated, apex rounded, 8–20 mm long, with 8–12 flowers, with 0 sterile bracts. Female bracts taller than flowers or at least twice as long as flowers, erect, 8–15 mm long, linear or ovate, acuminate, chartaceous, apical margin membranous, paler than body of bract, margins deeply lacerated or toothed, awn minute or absent. Female flower 5–6 mm long, without a fleshy pedicel, six tepals. Female tepals coriaceous or cartilaginous, glabrous and smooth, midrib flush with the tepal body, margins entire, apices acute or acuminate, inner whorl longer than outer or inner and outer whorls the same length (In some collections the inner whorl is larger than the outer whorl, but the long awns on outer tepals may break off leaving them to look shorter than the inner tepals. In other collections the inner whorl is more than twice as long as the outer). Female outer lateral tepals like other tepals or conduplicate, hidden by bracts, or bracts are shorter than flowers, 3–6 mm long. Female odd outer tepal ovate, 3–6 mm long. Female inner tepals oblong or ovate, 5–6 mm long. Staminodes present. Styles feathery, 3. Style bases free. Ovary with 3 locules or 1 locule (appears as if three carpels are present, but in the investigated material only one fertile chamber develops), dehiscent. Fruit: seed surface type seeds smooth, (1.04–)1.39(–1.76) mm long, (0.64–)0.78(–0.92) mm in diameter, shape in side view ovate, shape in diameter round in cross section, brown.
