Discussion

Variety viscidum is found throughout the northern range of the species from southeastern British Columbia, southern Alberta, and southwestern Saskatchewan to eastern Washington (Lincoln and Spokane counties), northern Idaho (as far south as Fremont County), and western Montana to the edge of the Great Plains. It appears to be disjunct near Tompkins, Saskatchewan (Looman 10304, OSC, UBC, UC, UTC); it approaches Dodecatheon pulchellum var. cusickii (not otherwise known from here); plants with both smooth and rugose connectives have been seen.

The distribution of the glands varies within plants. Most plants have at least the proximal portion of the scape glandular-puberulent; leaves and pedicels can be glandular or glabrous. Rarely is the entire scape glandular; these plants are confined mainly to the Waterton Lakes National Park area and are sometimes found elsewhere in Alberta. The calyx is rarely glandular. Even within the established range of var. viscidum, some populations may consist of both glandular and nonglandular individuals. Sometimes, only the pedicels have glands; in Wyoming such plants are assigned arbitrarily to var. conjugens. Plants with distinctly rugose connectives are termed here var. viscidum. H. J. Thompson (1953) assigned some Montana specimens with smooth or longitudinally wrinkled connectives to var. viscidum; here they are assigned to Dodecatheon pulchellum var. cusickii.
