Deer Indian Paintbrush - Castilleja cervina
State Rank Reason (see State Rank above)
Castilleja cervina is not documented in Montana (MTNHP Status Review in 2021). It was included in the Flora of Montana (Booth and Wright 1966) and Vascular Plants of Montana (Dorn 1984) possibly based on a specimen collected by R.S. Williams (1029) from "Columbia Falls, Mont." on July 10, 1894 and deposited at the Montana State University Herbarium (MONT 2775). However Mark Egger, author for the Castilleja treatment in the Flora of North America, determined that the specimen is Castilleja flava, which does match the identification for another Williams 1029 specimen collected on July 18, 1894 in "Columbia Falls" and deposited at the University of Montana Herbarium (MONTU 7081) (Egger pers. Comm.). A specimen collected in 1990 and deposited at the Rocky Mountain Herbarium (RM 561358; Brooks 19999) is most likely Castilleja flava based on the location but not the specimen itself (Egger pers. comm.).
Castilleja cervina is known from neighboring British Columbia and Alberta in Canada. If it does occur in Montana, it should be looked for in the very northwestern portion of the state (Egger pers. comm.). A conservation status rank is not applicable (SNA) because this plant is not known to occur in Montana.
Deer Indian Paintbrush is a perennial, hemiparasitic herb with clustered, erect, branched stems that are 3-6 dm high and which arise from a branched rootcrown. The lower leaves are linear and entire-margined, while the upper leaves have a pair of spreading lobes. Foliage is glabrous or has minute, curled hairs. Flowers are borne in a spike at the top of the stems. Each flower is subtended by a 3-5-lobed leaf-like bract, which is broader than the leaves with yellowish tips. The yellow, tubular corolla, 18-25 mm long, tapers to a short hood, or galea, above and to 3 small lobes below. The tubular calyx, 15-20 mm long, surrounds the corolla and is cleft more deeply below than above; each of the lateral lobes divide again into 2 pointed lobes which are 2-3 mm long. The fruit is a capsule with many tiny seeds.
Flowering and fruiting in July.
There are many species of yellow-colored Castilleja in our area. Castilleja pallescens and C. cusickii have glandular hairs on the galea, but C. cervina does not. C. rustica and C. lutescens have a calyces that are divided equally above and below. C. flava has foliage with longer, straight hairs.
Southern BC, adjacent northern ID and WA and northwest MT. Regional endemic.
