Cleistogenes ramiflora Keng fil. & C. P. Wang

No material of this species has been seen. The description is taken from the protologue. The spikelets are very similar to those of Cleisto-genes mucronata, but the habit is different, as shown in the illustration accompanying the protologue, with softly ascending leaf blades of more or less equal length throughout.

Culms tufted, erect or slightly decumbent at base, 25–35 cm tall. Leaf sheaths glabrous but pilose at mouth; leaf blades narrowly linear, flat or involute, ascending, 3–10 × ca. 0.2 cm; ligule short. Panicle narrow, 5–9 cm, lowest branch 2–4 cm. Spikelets 7–9 mm, florets 3–4; glumes lanceolate, 1-veined; lower glume 2–4 mm; upper glume 4–5 mm; lemmas lanceolate, purplish at margin and apex, lowest 5–6(–7) mm, acute or with a mucro to 0.5 mm; palea slightly shorter than lemma. Anthers ca. 3 mm. Fl. and fr. Jul–Sep.
