Bhidea borii

HABIT Annual. Culms erect; slender; 16 cm long. Culm-nodes pubescent. Leaf-sheaths glabrous on surface. Ligule an eciliate membrane. Leaf-blades 2.5–6 cm long; 2.5 mm wide. Leaf-blade surface glabrous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence composed of racemes; subtended by a spatheole. Spatheole linear; membranous.

Racemes 2; paired; 5 cm long; bearing few fertile spikelets; bearing 3–4 fertile spikelets on each. Rhachis fragile at the nodes; ciliate on margins. Rhachis internodes linear; 2 mm long. Rhachis internode tip oblique; cupuliform. Raceme-bases filiform.

Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; 2.5 mm long; ciliate; hairy on one margin.

STERILE SPIKELETS Basal sterile spikelets well-developed; 4 in number (lower raceme); 4 in upper raceme; barren; smaller than fertile. Basal sterile spikelet lower glume muticous.

Companion sterile spikelets well-developed; containing empty lemmas; lanceolate; asymmetrical; as long as fertile; persistent. Companion sterile spikelet callus square; truncate. Companion sterile spikelet glumes coriaceous; 2 mm long; winged on keels; awned; both glumes awned; with 7–9 mm long awn.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 2 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; 2.5 mm long; attached obliquely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume lanceolate; asymmetrical; 1 length of spikelet; coriaceous; 2-keeled; winged on keel; winged broadly; winged above. Lower glume apex acute; awned; 1 -awned. Lower glume awn 12 mm long. Upper glume oblong; 2 mm long; membranous; 1-keeled. Upper glume apex lobed; 3 -fid; awned; 1 -awned.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 1 mm long; hyaline. Fertile lemma oblong; 2 mm long; membranous; keeled. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 35 mm long overall; with twisted column. Column of lemma awn glabrous.

DISTRIBUTION Asia-tropical: India.
