Biennials, or short-lived perennials, 20–70 cm; taprooted (propagating by basal rosettes at proximalmost nodes of old stems and at ends of rhizomes and roots). Stems 1–5(–80 in subsp. cruiseana; from rosette), procumbent, ascending, or erect (sometimes purple-tinged), simple or branched, glabrous or densely woolly, proximally often sparsely glandular, distally sometimes densely so or eglandular. Leaves: (perennating rosettes often sparsely woolly); basal sessile, blades oblanceolate, 3–10 × 1–3 cm, margins sometimes apically dentate, faces sparsely to densely long-woolly; cauline leaves spreading to ascending, blades linear to linear-lanceolate, oblanceolate, oblong, or ovate-elliptic, reduced distally, margins entire, piloso-ciliate, apices obtuse to acute, sometimes mucronate, faces sparsely to densely woolly, sometimes glabrescent.

Discussion
Subspecies 3 (3 in the flora).
Chrysopsis gossypina is a highly variable species with a confusing range of variation in habit, leaf shape, indument, and phyllary traits. The very different-looking extremes that closely resemble other species appear to be the result of local adaptation and loss of one or the other ancestral parental traits from the allopolyploid genome. Three subspecies are recognized with mostly allopatric ranges. Intermediates between subspecies occur in areas where the ranges overlap in panhandle Florida.
Interspecific hybridization occurs in panhandle Florida near the coast between this species and C. godfreyi (J. C. Semple and C. C. Chinnappa 1980), and possibly also with C. linearifolia.
