Characteristics

Perennials, erect, caespitose. Flowering culms to 100 cm high. Leaves: basal leaf sheath margins glabrous; ligule a ciliate membrane, to 0.5 mm long; blade folded or convolute, linear, 4.35 cm long, to 3 mm wide, with smooth margins. Inflorescences of spicate main branches, irregular, contracted and spiciform, 13.30 cm long; primary branches solitary, equalling or longer than adjacent internodes, erect, spreading or appressed at apex of inflorescence, spikelet-bearing throughout, with spikelets in clusters. Spikelets shortly pedicellate, 1.5.2.3 mm long; pedicel to 1 mm long. Glumes: lower glume oblong or lanceolate, 0.3.1 mm long, obtuse (often torn), 0.1-nerved (faintly); upper glume lanceolate, at least half spikelet length, 0.7.1.4 mm long. Lemma lanceolate, 1.5.2.2 mm long, acute, faintly 3-nerved. Palea slightly shorter than lemma, entire. Anthers usually 2, to 0.6 mm long. Grain obovate, quadrangular (with sharp edges), 0.5.1 mm long (c. half spikelet length), to 0.6 mm wide, to 0.3 mm thick, reticulate, brown. Embryo ±half as long as grain.
More
Perennials, in dense strict clumps > 1 m; branching intravaginal. Leaf-sheath very light green to creamy brown, subcoriaceous or somewhat chartaceous, glabrous; margins sometimes short-ciliate below ligule. Ligule c. 0.3 mm. Collar hairs to 1 mm. Leaf-blade 15-45 cm ×c. 1 mm diam., inrolled, or flat and 2-4 mm wide, abaxially glabrous, adaxially finely scabrid on ribs; margins finely scabrid, long-tapered to fine tip. Culm internodes glabrous. Panicle 14-30 cm, ± lax with obvious, ascending branches, lowest branches often very distant and up to 2 cm; rachis ± smooth, branches sparsely scabrid bearing spikelets in dense spike-like clusters. Spikelets 1.5-2.5 mm, leaden green. Glumes unequal, < lemma; lower 0.5-0.8 mm, nerveless, oblong-elliptic, obtuse, upper 0.8-1.5 mm, 1-nerved, ovate-elliptic, subacute. Lemma = spikelet, faintly 3-nerved, elliptic-lanceolate, subacute. Palea ≤ lemma, narrowly truncate. Stamens 2; anthers 0.4-0.7 mm, yellow. Caryopsis 0.7-1.2 × 0.5-0.7 mm, oblong-ellipsoid, truncate.
