Manisuris myurus

HABIT Perennial. Culms 15–70 cm long. Ligule an eciliate membrane. Leaf-blades 5–15 cm long.

INFLORESCENCE Inflorescence composed of racemes; terminal and axillary.

Racemes 1; single; unilateral; 2–7 cm long. Rhachis fragile at the nodes; subcylindrical and excavated. Spikelet packing abaxial. Rhachis internodes cuneate. Rhachis internode tip transverse; crateriform.

Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels fused to internode; united wholly.

STERILE SPIKELETS Companion sterile spikelets well-developed; oblong; asymmetrical; 4 mm long; longer than fertile; fused to and deciduous with fertile spikelet belonging to segment above. Companion sterile spikelet glumes coriaceous; winged on keels; distinctly veined; truncate; muticous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 2.5–3 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus base truncate; with central peg; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; indurate; 2-keeled; keeled laterally; winged on keel; winged broadly; winged above and below (interrupted by waist). Lower glume surface transversely waisted. Lower glume apex emarginate; muticous. Upper glume oblong; membranous; 1-keeled; 3 -veined.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret hyaline. Fertile lemma elliptic; hyaline; without keel.

DISTRIBUTION Asia-tropical: India.

NOTES Andropogoneae. WDC.
