Gentianopsis virgata
Folia Geobot. Phytotax. 2: 120. 1967.
Herbs biennial or perhaps sometimes annuals, 0.2–5(–7) dm. Stems except those of smallest plants with branches or peduncles arising from nodes distinctly above base, infrequently from base (subsp. macounii). Leaves: basal usually withered by flowering, blades spatulate to oblanceolate, 0.8–6 cm × 1–18 mm, apex rounded to acute; cauline blades linear to linear-lanceolate, 1.5–9 cm × 2–9(–12) mm, apex acute. Peduncles 1–20 cm. Flowers 1–many; calyx 12–60 mm, keels usually minutely granular-scabridulous to strongly papillate-scabridulous proximally, sometimes smooth, all or at least inner lobes less than 1.5 times as long as tube, outer lobes linear-lanceolate, apices acuminate to attenuate, inner lobes lance-ovate to ovate, apices acute to acuminate; corolla deep blue or rarely pale blue, rose-violet, white, or pale yellow, 18–60(–75) mm, lobes oblong-obovate to ovate-elliptic or orbiculate, 10–30 × 3–18 mm, margins proximally fringed, distally dentate or erose, or sometimes entire (subsp. victorinii), apex rounded; ovary subsessile to long-stipitate. Seeds papillate, not winged.
