Aphanostephus riddellii is the only perennial in the genus. The caudex usually is woody, bearing numerous stems. The distal cauline leaves (upper half of stem) usually are linear, the basal and proximal cauline are conspicuously broader, spatulate, and dentate to pinnatifid. In other species, distal leaves usually are more similar to proximal.
