Digitaria connivens

HABIT Perennial; mat forming. Stolons present. Culms prostrate; 10–30 cm long (100–200cm long); rooting from lower nodes. Leaf-sheaths longer than adjacent culm internode. Ligule an eciliate membrane; 1.5–2 mm long. Leaf-blades 2.5–5.5 cm long; 2–5 mm wide. Leaf-blade margins cartilaginous.

INFLORESCENCE Inflorescence composed of racemes.

Racemes 2–5; paired, or digitate; erect; unilateral; 3–8 cm long. Rhachis wingless; angular; scaberulous on margins.

Spikelets in pairs. Fertile spikelets pedicelled; 2 in the cluster. Pedicels unequal.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or elliptic; dorsally compressed; acute; 4 mm long; falling entire.

GLUMES Glumes one the lower absent or obscure; reaching apex of florets; thinner than fertile lemma. Upper glume elliptic; 1 length of spikelet; membranous; without keels; 7 -veined. Upper glume surface glabrous. Upper glume apex acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; 1 length of spikelet; membranous; 9–11 -veined; glabrous; acute. Fertile lemma elliptic; 4 mm long; cartilaginous; much thinner on margins; without keel. Lemma margins flat; covering most of palea. Lemma apex acute. Palea cartilaginous.

DISTRIBUTION South America: Brazil.

NOTES Paniceae. Fl Cat.
