"Typical P. barbatus with a densely yellow-bearded palate is the common form in Mexico. Northward in the United States, however, the occurrence of bearded forms gradually decreases along with a gradual decrease in the amount of pubescence. Most plants in the northern part of its distribution bear glabrous palates and are referable to var. torreyi. A third variety, var. trichander, has varying degrees of pubescence on the anthers. The concept that this variety originated through introgression of woolly anthered P. strictus genes into P. barbatus was proposed nearly simultaneously by G. Moore and Crosswhite. Crosswhite observed that the distribution of var. trichander coincides with the region of overlap between P. barbatus var. torreyi and P. strictus." From Holmgren 1984 (Intermountain Flora).
