Morphology Reproductive morphology Inflorescences
Inflorescence composed of racemes. Racemes 1; single; linear; bilateral; 3-8 cm long; 3-5 mm wide. Rhachis fragile at the nodes; flattened; scabrous on margins; glabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 1-1.5 mm long; falling with spikelet above. Spikelets in threes. Fertile spikelets sessile; 1 in the cluster.
