Digitaria filiformis var. villosa

(Walter) Fernald
Treatment appears in FNA Volume 25. Treatment on page 366.

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.

Discussion

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.

Selected References

None.

Lower Taxa

None.

"decumbent" is not a number.
