Showy Indian Paintbrush - Castilleja pulchella
(see State Rank Reason below)
MNPS Threat Rank
State Rank Reason (see State Rank above)
Known from numerous collections from many of our major mountain ranges. The high elevation habitat also tends to limit potential threats to the the species. Does not appear to be at risk in Montana.
Perennial. Stems ascending, simple, 4–15 cm. Herbage glandular-pubescent. Leaves linear to lanceolate, 1–3 cm long, the lower entire, upper 3-lobed. Inflorescence puberulent, viscid-villous; bracts yellow to purplish, narrowly ovate entire or with a pair of lateral lobes. Flowers: calyx 15–21 mm long, primary clefts subequal, ultimate lobes rounded, 1–3 mm long; corolla 18–25 mm long, galea 3–5 mm long, lower lip 1–3 mm long (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX)
Known from the alpine tundra of the middle Rocky Mountains in southwestern Montana, western Wyoming, and northeastern Utah (Scott 1995). Also occurs in Idaho (Kartesz and Meacham 1999).
