Plants stoloniferous, not rhizomatous. Culms 5-30 cm. Sheaths glabrous; ligules membranous; blades 1.5-6 cm long, 2-4 mm wide, glabrous or pubescent. Panicles with 2-6 branches; branches 2-5 cm, in a single whorl, axes flattened. Spikelets 2-3 mm, narrowly to broadly ovate. Glumes 1.7-2.1 mm, exceeded by the florets; lemmas 2.2-2.6 mm, keels winged and pubescent, mar¬gins glabrous. 2n = 18, 36.

Discussion

Cynodon incompletus is native to southern Africa. A hybrid between the two varieties identified below, Cynodon xbradleyi Stent, is used as a lawn grass in North America (de Wet and Harlan 1970).

1. Blades glabrous or sparsely hirsute; spikelets 2.5-3 mm long, narrowly ovate var. incompletus 1. Blades densely hirsute; spikelets 2-2.5 mm long, broadly ovate var. hirsutus
