Culms 75-150 cm. Basal leaf sheaths with papillose-based hairs;
cauline leaf blades 1-6 mm wide, flat. Panicle branches 10-25 cm.
Spikelets 2-2.8 mm; lower lemmas pubescent.
Digitaria filiformis var. villosa has essentially the same geographic
range as var. filiformis and grows in similar habitats. Further study may show that the two varieties
should be combined.
