Rustic Indian Paintbrush - Castilleja flava var. rustica
Other Names:
Castilleja rustica
General Description
Perennial; stems clustered, ascending to erect, usually branched above, 20-40 cm tall. Stems appressed hairy, often purplish. Leaves densely hairy, the lower ones linear and entire, the upper usually with 1-2 pairs of linear, divergent lobes. Bracts broader than the leaves, 3-5 parted, hairy, yellowish or occasinally reddish. Flowers rather remote and not hidden by bractes. Calyx 12-23 mm long, deeply and subequally cleft above and below, its primary lobes again divided into 2 triangular, acute segments 2-6 mm long. Corolla 15-25 mm long, usually longer than calyx; lower lip reduced, 1/2-1/5 length of the galea, its lobes and sometimes its pouch hairy (Ownbey, 1959, Vasc. Pl. Pac. Northwest, Part 4).
