Plants stoloniferous (the stolons to 6 m), sterile. Basal sheaths glabrous or hirsute. 2n = 27 (for Digitaria decumbens Stent).

Discussion

In the Western Hemisphere, D. eriantha subsp. pentzii has traditionally been referred to as D. decumbens Stent. It is widely cultivated as a forage grass throughout the tropics at low and intermediate altitudes (up to 2000 m). It does not set seed; propagation is by sprigging the stolons.
