Soft, slender, short-lived perennial or annual, up to 400 mm high; often mat-forming; culms prostrate or trailing. Leaf blade up to 10-80 x 14 mm; ligule an unfringed membrane. Inflorescence of 2-6 racemes, scattered up a slender central axis; appears different as upper glume hooks only develop after fertilisation and delayed maturation of sessile spikelets causes an extended flowering period. Spikelets 3.5-5.0 mm long, laterally compressed, often burr-like, awnless; glumes ± equal, dissimilar; upper glume gibbous, as long as spikelet, translucent spots between nerves which usually have stiff hooked hairs after fertilisation. Florets 2; lower floret male or sterile; upper floret bisexual, lemma hard; anther 1.0-1.5 mm long. Flowering time Aug., Sept., Dec.-Apr.
Culms slender, stoloniferous, rooting and forming a loose mat, up to 50 cm tall. Leaf sheaths usually shorter than the internodes; leaf blades lanceolate, thin, 2–8 × 0.6–1.2 cm, glabrous or hispidulous, apex acute or acuminate; ligule 1–2 mm. Inflorescence narrow, 5–15 cm, bearing 3–5 loosely ascending racemes with distant spikelet pairs, lowest raceme 1–4 cm; pedicels 1–2 mm. Spikelets 4–5 mm; glumes papery, the lower lanceolate, 3-veined, acuminate, the upper thicker, navicular, 7-veined, with tubercle-based hooks between the veins; lower lemma 7-veined; upper lemma subcoriaceous, ca. 3 mm, pale, glossy. Caryopsis fusiform, ca. 2.5 mm, acute. Fl. and fr. Sep–Oct. 2n = 36.
Annual with slender prostrate culms, often forming a mat; culms 10–30 cm. high.. Leaf-blades 1–8 cm. long, 3–14 mm. wide.. Inflorescence 2–20 cm. long, the lowest raceme 1–6 cm. long, with distant spikelets.. Spikelets 3.5–5.7 mm. long; lower glume lanceolate to elliptic, almost as long as the spikelet, acute to acuminate; upper glume strongly gibbous, mostly as long as the spikelet, armed with hooked bristles or these often reduced to short appressed hairs; upper lemma subcoriaceous.. Fig. 131.
Soft slender, short-lived perennial or annual up to 400 mm high, often mat-forming; culms prostrate or trailing. Leaf blade 10-80 x to 14 mm; ligule an unfringed membrane, thin, truncate. Spikelet 3.5-5.0 mm long, obliquely ovoid, often burr-like; upper glume usually with stiff hooked hairs after fertilisation; anthers 1.0-1.5 mm long.
Soft slender perennial or annual (often mat-forming), up to 400 mm tall. Leaf blades 10-80 mm long, up to 14 mm wide. Culms prostrate. Spikelets 3.5-5.0 mm long (reduced spikelets often present), burr-like; upper glume usually with stiff hooked hairs.
Trailing annual with lanceolate leaf laminae, and often with aerial roots at the nodes.
Glumes acute to acuminate, wingless, the inferior almost as long as spikelet.
Spikelets 3.5–5.7 mm. long, obliquely ovoid.
Superior lemma subcoriaceous.
Culms 10–30 cm. high.
