State Rank Reason (see State Rank above)
An uncommon species in Montana, where it is known from mountainous areas of the southwest and south-central portions of the state. Appears to be common and widespread enough that its viability is not at risk in the state.
 
General Description
Perennial. Stems erect, simple, 20–50 cm. Herbage puberulent. Leaves 2–7 cm long, linear to linear-lanceolate, the upper with 1 pair of linear lobes. Inflorescence glandular-puberulent, villous; bracts bright red, lanceolate with 1 or 2 pairs of lateral lobes. Flowers: calyx 20–28 mm long, primary clefts deeper in front than in back, lobes acute to acuminate, 3–8 mm long; corolla 26–36 mm long, galea 10–13 mm long, lower lip green, minute (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).

Diagnostic Characteristics
Castilleja is a difficult genus because hybridization and allopolyploid speciation (containment of multiple sets of chromosomes that are derived from different species) fuzz a species’ characteristics (Giblin et al. [eds.] 2018).

To identify Castilleja species, it is important to (Giblin et al. [eds.] 2018):
* note colors of the bract, calyx, and corolla while in the field, and
* press many bracts, calyces, and corollas separately to show their shapes.

Castilleja linariifolia and Castilleja crista-galli can be mistaken for one another. It is speculated that Castilleja crista-galli is a hybrid product of Castilleja linariifolia x Castilleja miniata, because it can exhibit intermediate morphology. Studies are needed.

Greater Red Indian PaintbrushCastilleja crista-galli, native:
* Inflorescence bracts are bright red.
* Primary calyx lobes are cleft deeper in front than in the back.
* Calyx lobes are acute to acuminate.

Wyoming Indian PaintbrushCastilleja linariifolia, native:
* Inflorescence bracts yellow to orange.
* Flowers become more widely separated at maturity (than does C. crista-galli)
* Calyx is conspicuously more deeply cleft on the side adjacent to the corolla lip than on the back. Calyx is curved back.
* Calyx lobes are acute.
