Cynosurus peltieri

HABIT Annual; caespitose; clumped loosely. Rhizomes elongated. Culms 30–70 cm long. Culm-internodes distally glabrous. Leaf-sheaths without keel; smooth; glabrous on surface. Ligule an eciliate membrane; 0.5–1 mm long; truncate. Leaf-blades flat; 15–30 cm long; 1–2.5 mm wide; stiff. Leaf-blade surface smooth; glabrous. Leaf-blade margins smooth. Leaf-blade apex acute; callose.

INFLORESCENCE Inflorescence a panicle.

Panicle spiciform; linear; interrupted; secund; 4–16 cm long; 0.5–1.2 cm wide. Panicle axis angular; scaberulous. Panicle branches puberulous.

Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets sessile; 1 in the cluster.

STERILE SPIKELETS Companion sterile spikelets well-developed; containing empty lemmas; oblong; laterally compressed; 4–6 mm long; as long as fertile; persistent. Companion sterile spikelet lemmas 4–7; exserted from glumes; 4–6 mm long; 1-awned; with 1–2.5 mm long awn.

FERTILE SPIKELETS Spikelets comprising 1–2 fertile florets; with a barren rhachilla extension. Spikelets oblong; laterally compressed; 4–6 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes smooth.

GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4–6 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 0.5–1 mm long. Upper glume lanceolate; 4–6 mm long; 0.9–1.1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn 0.5–1 mm long.

FLORETS Fertile lemma ovate; 5 mm long; chartaceous; without keel; 5 -veined. Lemma surface scaberulous; rough above. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1 mm long overall. Palea 1 length of lemma. Palea keels scaberulous; adorned above.

FLOWER Lodicules 2; 0.5–0.6 mm long. Anthers 3; 2.5 mm long.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Africa: north.

NOTES Poeae. Fl Afr N 1997.
