Danthoniopsis parva

HABIT Perennial. Rhizomes elongated. Culms decumbent; 10–30 cm long; 5 -noded; rooting from lower nodes. Culm-nodes glabrous. Ligule a fringe of hairs; 1 mm long. Leaf-blades 2–5.5 cm long; 1–2 mm wide. Leaf-blade apex attenuate.

INFLORESCENCE Inflorescence a panicle.

Panicle open; elliptic; 2–5 cm long. Primary panicle branches 1–2 -nate. Panicle axis pubescent. Panicle branches capillary; pilose.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels unequal.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 4.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; bearded; truncate.

GLUMES Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate, or ovate; 3 mm long; 0.75 length of upper glume; chartaceous; without keels; 3 -veined. Lower glume surface puberulous to pilose. Lower glume apex acute. Upper glume lanceolate, or ovate; 4 mm long; 0.9 length of spikelet; chartaceous; without keels; 5 -veined. Upper glume surface pubescent, or pilose. Upper glume apex acute.

FLORETS Basal sterile florets male; with palea; separately deciduous. Lemma of lower sterile floret similar to upper glume; lanceolate; 4.5 mm long; membranous; 5(–7) -veined; truncate. Palea of lower sterile floret pubescent; adorned on keels. Fertile lemma oblong; 4 mm long; coriaceous; without keel; 5–7 -veined. Lemma surface pilose; with a transverse row of hair tufts; bearing 6 hair tufts in all. Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; with lobes 1.2 mm long; incised 0.33 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; flat below; 8 mm long overall; with twisted column. Palea 2 -veined. Palea keels contiguous above a sulcus; thickened; winged; narrowly winged; ciliolate.

FLOWER Lodicules 2; cuneate; fleshy. Anthers 3; 2 mm long.

FRUIT Caryopsis with adherent pericarp.

DISTRIBUTION Africa: south.
