Perennial herb from a superficial, woody stem-base, smooth throughout except for the flowers; often with short leafy mat-forming stems at the base, the flowering stems usually several, clumped, ascending to erect but often decumbent-based, (5) 10-40 cm tall, slender.

Leaves:
Basal leaves stalked, lanceolate to spoon-shaped, 3-10 cm long, entire, sometimes poorly developed; stem leaves few, opposite, lanceolate, entire, unstalked, smaller than the basal leaves.

Flowers:
Inflorescence a slender terminal cluster, compact and spike-like or interrupted below, of 1 to several dense whorls of several stalked flowers, the bracts entire; corollas narrowly tubular, 0.6-1.2 cm long, deep purple-blue but occasionally pinkish or yellowish-white, 2-lipped, smooth on the outside, hairy within at the throat; calyces 3-6 mm long, 5-lobed, the lobes oblong to egg-shaped, gradually tapering to a sharp tip or abruptly sharp-pointed, minutely hairy, the margins often papery and ragged at least near the base; fertile stamens 4, the anthers smooth; sterile stamen about as long as the fertile stamens, yellow-bearded at its expanded tip.

Fruits:
Capsules, 3-5 mm long; seeds numerous, 0.5-1 mm long.

Notes:
Two varieties occur in BC

1. Basal rosettes poorly developed; plants mostly 20-40 cm tall, usually with more than 1 whorl of flowers per stem; throughout range of the species................. var. procerus

1. Basal rosettes well developed; plants mostly 5-15 cm tall, usually with only 1 whorl of flowers per stem; SC BC, largely in the Cascade Mtns...................... var. tolmiei (Hook.) Cronq.
