(Discussion copyrighted by Flora of North America; reprinted with permission.)
Variety subviscosa is widespread in the mountains of New Mexico and north of the Mogollon Rim in Arizona, barely entering Colorado in the Sangre de Cristo Range. The variety often has striking seasonal differences in leaf shape and petiole vestiture, best developed in Arizona populations. Leaves formed early in the season and coinciding with peak flowering have deeply divided leaflets, and the petiole vestiture often consists almost exclusively of glands. Later-formed leaves are sometimes significantly larger and have progressively less deeply divided leaflets and increasing densities of both short and long hairs.
