Digitaria jubata appears to be a species of rather restricted distribution. It is similar to D. abludens, but has taller, solitary (vs. tufted) culms, and longer racemes with the branchlets and pedicels lying closer to the rachis (vs. widely spreading). The spikelet pubescence is denser, with more obviously pin-headed hairs.
