Rough-hairy; stem stout, 6—24 inches high. Leaves white-hairy, lanceolate to ovate, acute, pinnately and obliquely, striately veined, the lower tapering into petioles, commonly with 1—2 pairs of small lateral leaflets. Flowers in a dense spike; corolla bluish, longer than the oblong-lanceolate or linear calyx lobes; filaments much exserted, sparingly bearded.
In the Cougar Valley in the Selkirks; flowering in July.
Silky-hairy or canescent throughout, 6—18 inches high, leafy to the top. Leaves pinnately parted into linear or narrow oblong, numerous, often pinnatifid divisions, the lower petioled, the upper nearly sessile. Flowers crowded in an elongated spike, corolla violet, blue or white, open-campanulate, cleft to the middle; stamens much exserted.
In dry ground and open slopes throughout the region; flowering in June and July.
Stems slender, weak, 3—6 inches long. Leaves mainly at the root, with slender petioles, alternate, round-cordate, or reniform, with 7—11 crenate, glandular-tipped lobes. Flowers more or less racemose on slender, weak scapes with spreading pedicels longer than the flowers; calyx lobes smooth, much shorter than the delicately veiny pale pink or usually white funnel-form corolla with yellow throat and broad rounded lobes.
On constantly dripping ledges of wet rocks, rare in the region generally but rather frequent about Lake Louise and Lake O’Hara; flowering during July.
