Deyeuxia kashmiriana

HABIT Perennial. Culms slender; 30–50 cm long; 3–4 -noded. Culm-internodes distally glabrous. Leaf-sheaths mostly shorter than adjacent culm internode. Ligule an eciliate membrane; 3–4 mm long; scaberulous on abaxial surface; entire, or erose; obtuse. Leaf-blades flat, or involute; 2–10 cm long; 1–2 mm wide. Leaf-blade surface scaberulous. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear, or oblong; 7–15 cm long; 1–1.5 cm wide. Primary panicle branches appressed. Panicle axis with lower internodes 1–1.5 cm long; scabrous. Panicle branches scabrous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5–3 mm long; scabrous.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with a barren rhachilla extension. Spikelets lanceolate; laterally compressed; 5–5.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent. Floret callus hairs 0.2–1 mm long.

GLUMES Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 1 length of upper glume; membranous; much thinner on margins; 1-keeled; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume surface asperulous. Lower glume apex attenuate. Upper glume lanceolate; 5–5.5 mm long; 1 length of adjacent fertile lemma; membranous; with scarious margins; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume surface asperulous. Upper glume apex attenuate.

FLORETS Fertile lemma lanceolate; 5–5.5 mm long; chartaceous; without keel; 5 -veined. Lemma lateral veins obscure. Lemma surface scaberulous. Lemma apex entire, or erose; acute; awned; 1 -awned. Principal lemma awn dorsal; arising 0.5 way up back of lemma; geniculate; 5 mm long overall; clearly exserted from spikelet; with twisted column. Palea 3.5–4 mm long. Palea keels scaberulous; adorned above. Rhachilla extension 2 mm long; pilose; with 1.5 mm long hairs.

FLOWER Lodicules 2. Anthers 3; 0.5–1.2 mm long. Stigmas 2.

FRUIT Caryopsis with adherent pericarp. Hilum punctiform. Disseminule comprising a floret.

DISTRIBUTION Asia-tropical: India.
