Basal leaves numerous, gradually tapering into basal, oblong-oblanceolate or linear-oblong, rarely obovate, 10–50 × 3–10 mm, glabrous above, sparsely adpressed strigose below; cauline leaves sessile, oblong-oblanceolate or linear-oblong, 5–20 × 1–4 mm, glabrescent above, sparsely adpressed strigose below.  Inflorescence corymbose-paniculate, up to 20-flowered; pedicel 2–12-mm-long at anthesis, up to 20 mm at fruiting, adpressed-hirsute. Calyx divided nearly to the base, sepals oblong lanceolate or oblong, 7–11 × 1–3 mm at anthesis, longer at fruiting, glabrescent to glabrous outside, hirsute at margin, glabrous inside. Corolla longer than calyx, campanulate, 5–16-mm-long, tube and limb equal or tube shorter than limb, tube 2–8-mm-long, limb 3–8-mm-long, lobes 1–2 × 1.5–4 mm, rounded at apex.
