Basal leaf petiole slightly shorter than to 1/2 as long as leaf blade; leaf blade glabrous or abaxially floccose-pubescent along veins, pinnatisect; segments lanceolate, pinnatifid, dentate, teeth callose, apex acute. Stem leaves similar to basal leaves but shorter petiolate. Flowers initially in a dense raceme, later elongating to 17 cm in fruit; proximal bracts leaflike, distal ones linear. Pedicel ca. 1 cm basally. Calyx 1--1.4 cm, villous, densely reticulate-veined; lobes 5, unequal, triangular-lanceolate, ca. 1/3 as long as tube. Corolla purple-red, 2--2.5 cm; tube ca. 1.5 X longer than galea; galea ± falcate, beakless, apex marginally 2-uncinate toothed; lower lip shorter than galea. 2 filaments pubescent and 2 glabrous or all 4 glabrous.
