Pyrrocoma hirta is recognized by its relatively short stature, villous, glandular-stipitate stems, lanceolate, coarsely serrate leaves, and loose, racemiform arrays. R. A. Mayes (1976) suggested that it is closely related to P. lanceolata. Much overlap occurs in the characters used to differentiate the varieties.
