Discussion

Variety cusickii is densely glandular-pubescent to glandular-puberulent. It occurs from northeastern Oregon to southeastern British Columbia, thence across Idaho to western Montana, with a disjunct population at Birdseye, Wyoming (A. Nelson 9610, 4 May 1911; DS, RM-mixed with Dodecatheon conjugens). Its range is well within that of var. pulchellum. The whole plant (leaves, scapes, pedicels, and calyx) is densely glandular, unlike D. conjugens var. viscidum, which usually has sparsely and minutely glandular-puberulent pedicels, leaves, and scapes that are (typically) glandular-pubescent proximally. Plants from Alberta and Saskatchewan assigned previously to var. cusickii are var. viscidum.
