Species Information

Plants fibrous-rooted; roots whitish; bulblets absent.
Leaves lanceolate or oblanceolate to narrowly ovate, base gradually to abruptly tapering to the short, broadly winged petiole, entire, surfaces usually glandular-puberulent (at least along the margins) or rarely glabrescent, 3-13 (20) cm.
Inflorescences of 1-7 (10) flowers; involucral bracts lanceolate, glandular-puberulent, 3-10 mm. Flowers long-stalked; corolla tube and throat yellow, with a fine, wavy, reddish ring around the throat; corolla lobes pink (rarely white), 7-25 (35) mm; pollen sacs usually purplish-brown, sometimes yellowish or purple-spotted; calyces green, sometimes purple-speckled, usually glabrous (sometimes glandular), 5-12 mm; filaments usually distinct to their base (sometimes slightly connate), yellow or purplish-spotted to wholly dark purplish-brown; connective purplish-brown, usually with some yellow (at least apically), transversely rugose; stigma not enlarged relative to the style; pedicels glandular-puberulent, 1-5 cm. . Flowering Apr-Jun.
Capsules tan, cylindric, circumcissile, 8-12 mm.
Scapes usually glandular-puberulent on the lower portion (rarely entirely glandular), 5-30 cm tall.

Taxonomic Notes

Dodecatheon conjugens may potentially hybridize with D. pulchellum var. pulchellum based on occasional individuals with narrower leaves and slightly connate filaments. D. conjugens var. viscidum may be confused with the similarly glandular D. pulchellum var. cusickii, with which it often grows, and care is advised when attempting to distinguish these two taxa. Variety conjugens is best separated from var. cusickii by its transversely rugose connectives (vs. smooth or longitudinally wrinkled in var. cusickii), typically broader and rounder leaves, circumcissile (vs. 5-valvate) capsules, and the usually sparsely glandular-puberulent (vs. densely glandular-pubescent) leaves, pedicels, and scapes. The more southern D. conjugens var. conjugens, which is largely glabrous and lacks the extensive glandular puberulence of var. viscidum, has been attributed for B.C. by many authors, but these reports are apparently based on glabrescent examples of var. viscidum. The nominate variety occurs north to northern Washington, northern Idaho, and northwest Montana, and occasional reports from B.C. may be the result of introgression of the two subspecies in border areas.
