Culms are decumbent, with heights ranging from 25 to 70 cm. Racemes are single, oblong, bilateral, and 4–10 cm long; spikelets are oblong, laterally compressed, and 7–20 mm long.
D. villosum has almost total immunity against Puccinia graminis f. sp. tritici[2][3] and carries Sr52 which offers some resistance against the Ug99 subrace of P.g.f.sp.t..[2][3] The genetic basis for this immunity is being introgressed into its close relative, wheat,[2][3] which is suffering from new races of this disease.
