Stems erect, 18–50 cm, sparsely to moderately pubescent (gla­brate); branches borne on distal part of stem (rarely on most of length), at least slightly ex­ceeding infructescence. Leaves: petiole 0–1(–2) mm, glabrate or sparsely pubescent; blades heteromorphic; stem leaf blades narrowly elliptic to narrowly lanceolate, lanceolate, or ligulate, (2.5–)3.2–5.2(–6.7) cm × (3–)5–7(–10) mm, margins entire, slightly revolute, sometimes in part sparsely ciliate, apex acute, surfaces glabrous (sparsely pubescent on midrib); branch leaf blades linear to ligulate, 2.5–5.5 cm × 1–4 mm. Flowers: sepals subulate to narrowly deltate, (3–)4–6 mm; corolla tube iridescent blue to purplish, (16–)18–23 mm, lobes white to cream, (6.5–)8–11(–13) mm, outer surface of corolla glabrous. Follicles erect, (2.4–)3.7–6(–8.3) cm × 2–4 mm, apex acuminate, glabrous. Seeds 8–10 × 2–3 mm.

Flowering late spring; fruiting late spring–early summer. Rocky slopes and ridges, washes, sand dunes; of conservation concern; 1100–1700 m; N.Mex.
