Germainia lanipes
HABIT Perennial. Butt sheaths woolly; with white hairs. Culms 20–45 cm long; 3–5 -noded. Ligule a fringe of hairs. Leaf-blades 20–30 cm long; 2–3 mm wide. Leaf-blade surface scabrous.
INFLORESCENCE Inflorescence composed of racemes.
Racemes 1–2; single, or paired; appressed back to back; erect; oblong; 1.5–2.5 cm long; bearing few fertile spikelets; bearing 4–11 fertile spikelets on each. Rhachis obsolete (raceme capitate).
Spikelets in pairs. Fertile spikelets pedicelled; 1 in the cluster. Companion sterile spikelets sessile; 1 in the cluster. Pedicels 2–3 mm long.
STERILE SPIKELETS Basal sterile spikelets well-developed; 2 in number; forming an involucre about the fertile; subsessile. Basal sterile spikelet glumes coriaceous.
Companion sterile spikelets well-developed; male; oblong; dorsally compressed; 10–15 mm long; longer than fertile; persistent. Companion sterile spikelet glumes coriaceous; 7–9 -veined (lower); glabrous; entire; emarginate, or truncate; muticous. Companion sterile spikelet lemmas 2; enclosed by glumes; 9–10 mm long; entire; muticous.
FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 5–7 mm long; falling entire. Spikelet callus linear; 0.5–1 mm long; base pungent; attached obliquely.
GLUMES Glumes similar; reaching apex of florets; firmer than fertile lemma. Lower glume lanceolate; 5–7 mm long; 1.2 length of upper glume; 1 length of spikelet; chartaceous; without keels; 3–5 -veined. Lower glume apex obtuse. Upper glume lanceolate; 5–6 mm long; chartaceous; without keels; 3 -veined. Upper glume apex obtuse.
FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 2.8–3.2 mm long; hyaline. Fertile lemma linear; hyaline; without keel. Lemma apex entire; awned; 1 -awned. Principal lemma awn geniculate; 30–50 mm long overall; with twisted column. Column of lemma awn 15–25 mm long; pubescent. Palea absent or minute.
FLOWER Lodicules absent. Anthers 2; 2 mm long.
DISTRIBUTION Asia-tropical: Indo-China.
NOTES Andropogoneae. Chaianan.
