Specimens of Platyschkuhria integrifolia with stems leafy over 3/4+ of their lengths have been called var. oblongifolia (mostly from 'four-corners' area of Arizona, Colorado, New Mexico, and Utah). Those with leaves mostly on proximal 1/10-3/4 their stem lengths, peduncles little or not at all stipitate-glandular, and phyllary tips ± caudate have been called var. ourolepis (mostly from Uinta Basin, Utah). Those with leaves mostly on proximal 1/10-3/4 their stem lengths, leaf blades widest beyond their middles and rounded at tips, peduncles ± stipitate-glandular, and phyllary tips acute to acuminate have been called var. nudicaulis (mostly from Montana and Wyoming). Those with leaves mostly on proximal 1/10-3/4 their stem lengths, leaf blades widest proximal to their middles and acute at tips, peduncles ± stipitate-glandular, and phyllary tips obtuse to acute or acuminate have been called var. desertorum (mostly from western Colorado and eastern Utah).
