Arthraxon lancifolius (Trin.) Hochst.

Arthraxon lancifolius has been confused in the past with Arthraxon microphyllus (Trin.) Hochst. (Arthraxon sikkimensis Bor) a species now recognised as confined to the Himalayas in Nepal, Sikkim and Assam (See Jain in Indian Forester 97: 220-222. 1971).

Young inflorescences should be examined for pedicelled spikelets, as these may be present only at the tips of the racemes and soon disarticulate.

Annual; culms slender, 5-30 cm long, usually trailing. Leaf-blades lanceolate to narrowly ovate, 1-4 cm long, 3-10 mm wide, delicate, flaccid. Inflorescence of 2-9 racemes, each 1-2 cm long; internodes long-ciliate, the hairs attaining 1-2 mm towards the summit. Sessile spikelet linear, 2-3(-5) mm long; lower glume membranous, strongly convex on the back, scaberulous; upper glume produced into a fine bristle 0.5-1.5 mm long; awn 6-10 mm long; anthers 2, 0.3-0.6 mm long. Pedicelled spikelet lanceolate, 1 -2(-3) mm long, rarely quite suppressed.

Annual, delicate. Culms loosely tufted, very slender, decumbent, much branched, up to 30 cm long, glabrous or pubescent. Leaf sheaths loose, margin ciliate; leaf blades elliptic to narrowly ovate, thin, flaccid, 0.5–4 cm × 2–9 mm, puberulent to densely pubescent, often with scattered tubercle-based hairs, base cordate, basal margins pectinate-setose, apex setaceously acuminate; ligule 0.7–1.5 mm. Racemes 2–9, 1–2.5 cm; rachis internodes 1/2 length of sessile spikelets, margins silky ciliate, hairs increasing to 1.5–2.5 mm at apex. Sessile spikelet 2–3.3 mm; lower glume linear, strongly convex, margins not inflexed, veins indistinct in lower part, scaberulous toward apex, apex finely 2-toothed; upper glume extended into 0.5–1.5 mm apical mucro; awn 4–8 mm; palea absent. Anthers 2, 0.5–0.7 mm. Pedicelled spikelet usually present at least at raceme apex, lanceolate, 1.5–2.5 mm, sterile, usually composed of 2 empty glumes. Fl. and fr. Sep–Nov. 2n = 18, 36.
