Saccharum griffithii

HABIT Perennial; caespitose. Culms erect; robust; 100–200 cm long. Ligule a ciliate membrane. Leaf-blade base tapering to the midrib. Leaf-blades flat, or involute; 30–60 cm long; 4–6 mm wide; glaucous. Leaf-blade midrib widened.

INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme. Peduncle glabrous.

Panicle open; oblong; 20–35 cm long; 4–5 cm wide. Panicle axis glabrous.

Racemes 1.5–2.5 cm long; bearing few fertile spikelets; bearing 4–8 fertile spikelets on each. Rhachis fragile at the nodes; subterete; pilose on surface. Rhachis hairs 4–6 mm long. Rhachis internodes linear.

Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster; subequal. Pedicels linear; ciliate; with 4–6 mm long hairs.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4–5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base truncate. Spikelet callus hairs yellow; 2–4 mm long; 0.5–0.9 length of spikelet.

GLUMES Glumes similar; firmer than fertile lemma. Lower glume lanceolate; 1 length of spikelet; membranous; much thinner above; pallid and red (at tip); 2-keeled. Lower glume surface flat; pubescent to villous. Lower glume margins ciliate. Lower glume apex acuminate. Upper glume lanceolate; 1 length of spikelet; membranous; much thinner above; without keels. Upper glume surface pubescent to villous. Upper glume margins ciliate. Upper glume apex acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; hyaline; ciliolate on margins; acute. Fertile lemma lanceolate; hyaline. Lemma apex muticous, or awned. Principal lemma awn 0–4 mm long overall. Palea absent or minute.

FLOWER Lodicules 2; cuneate; ciliate. Anthers 3.

DISTRIBUTION Asia-temperate: western Asia and Arabia. Asia-tropical: India.
