Acaulescent perennial herb. Rhizome creeping, stout, to 4(–6) mm thick, softly pubescent, with prominent leaf scars. Leaves tending to cluster towards rhizome apex, usually rosulate though occasionally solitary; blade narrowly oblong-elliptic or oblong-lanceolate, size variable, 7–36 cm long, 1.5–17.5 cm wide, base ± asymmetric, cuneate to acute, margin coarsely dentate, apex subacuminate or acute, often withered, densely pubescent particularly on the upper surface and nerves beneath; lateral nerves 19–35 pairs, parallel, spreading; petiole 0.5–2(–4) cm long. Inflorescences apparently axillary, solitary to several arising from the leaf axis, somewhat lax and spreading, 8–many-flowered; peduncles 4–29 cm long; pedicels 7–17(–28) mm long, glandular- and eglandular-pubescent; bracts linear, 2–4.5 mm long, pubescent. Calyx lobes lanceolate, 1.5–3.5 mm long, glandular- and eglandular-pubescent. Corolla pale- or less commonly medium-violet, rarely whitish, with violet stripes on the floor of the tube, 11.5–19 mm long, scattered glandular-pubescent outside; tube obliquely cylindric with a declinate floor, 7–11 mm long, 5–7.5 mm deep, mouth open; limb bilabiate; upper lip of two suberect, rounded lobes, 2.5–3 mm long, ± 2.5 mm wide; lower lip of three spreading, oblong-rounded lobes, 4–4.5 mm long, 2–3.5 mm wide. Stamens arising from near the base of the corolla tube; filaments U-curved, slender, 4–6 mm long, glabrous; anther thecae rounded, 0.7–0.8 mm wide; staminodes minute. Ovary 3–4.5 mm long, glandular-pubescent; style 3–4 mm long; stigma bilobed, 0.35–0.4 mm wide, papillose. Capsule 15–25 mm long, 1–1.5 mm diameter, glandular-pubescent. Seeds 0.5–0.7 mm long, verruculose, slightly ridged longitudinally. Fig. 4, p. 29.
