Discussion
Variety sileri is known from northern Arizona, southern Nevada, and southwestern Utah. Plants with glabrous or nearly glabrous leaves from northern Arizona and southern Utah have been referred to var. viridis. As noted by N. H. Holmgren (1984), such forms occur sporadically through much of the range of var. sileri, suggesting that taxonomic recognition of var. viridis is unwarranted. Some specimens included in var. sileri from northern Arizona, especially from the Kaibab Plateau, have the habit of subsp. compactifolius (included here in var. linarioides) but the leaf pubescence of var. sileri (or var. viridis). Holmgren identified three morpho-geographic races that may warrant recognition.
