Erect caespitose perennial, 20–70 cm tall, the culms glabrous or sparsely pubescent on nodes. Leaf sheaths glabrous. Ligule membranous, truncate. Leaf blades filiform, rolled, firm, 5–15 × 0.1–0.2 cm, drying green-brown, basally sparsely pilose above. Panicles terminal, fully exserted, 5–10 cm long, ovate, the branches wiry, appressed to spreading, glabrous, the pedicels filiform and undulating, 2–10 mm long. Spikelets subglobose to ovate, apically acute, 1.5–1.8 mm long, usually purple or brown, gaping open at maturity. Lower glume 3/4–4/5 as long as the spikelet, obtuse to acute, with hyaline edges, 3–5-veined, pilose separated from the rest of the spikelet by an internode of c. 0.3 mm. Upper glume as long as the spikelet, herbaceous, 5-veined, pilose. Lower floret male, with palea. Lower lemma herbaceous, 5-veined, glabrous. Upper lemma shorter than the lower floret dull, finely verruculose, the small verruccae difficult to see without a microscope.

Distribution and ecology. – Tropical African species; distribution in Madagascar limited to open seasonally flooded and grazed grassland and tapia forest on the High Plateau, 800–1800 m ( Fig. 16B View Fig ).

Notes. – Recognisable by its filiform leaves, pilose spikelets, and a lower glume almost as long as the spikelet. The panicle resembles the sympatric Panicum ibitense and can be distinguished from that species by its erect tufted habit, basal leaves, and a lack of swollen underground storage organs.

This species is illustrated by BOSSER (1969: Fig. 119a-d as Panicum decaryanum ) and by ZULOAGA et al. (2011: Fig. 8 View Fig ).
