Resprouting shrub, 30-80 cm high. Branches caulous, antrorse, herbaceous branches hairy, woody branches glabrescent. Leaves herbaceous, cauline, transversely incurved, longitudinally straight to slightly naviculate, dead basal leaves not persistent, (7-)10-21(-26) x (4.0-)4.5-7.0(-9.0) mm, oblong to lanceolate, adaxially sparsely to copiously hairy, if sparsely hairy then hairs more or less evenly spread, abaxially sparsely or copiously hairy, if sparsely hairy then hairs more or less evenly spread, indumentum spinous to appressed, hairs similar in length, trichomes pustular; leaf margin entire; apex mostly obtuse; mid-vein abaxially prominent. Inflorescence of many flowered, compound cincinni, young flowering axis compact, flower buds commonly arranged into two parallel rows, spreading slightly in fruiting stage. Bracts (4-)5-12(-13) x (1.5-)2.0-5.0(-6.0) mm, lanceolate to ovate. Flowers medium sized (anterior petals 17-30 mm long), more than three per cymule, funnel-shaped, lower part of corolla tube not narrow, but flaring immediately. Sepals narrowly oblong, slightly less than half to half of corolla length, similar in width, free, adaxially and abaxially copiously hairy, non-velutinous; young apices incurved to applanate, brown trichomes on the adaxial surface present. Petals dissimilar, the anterior petal lobes larger than the rest, posterior petals ca. 18-20 mm long, posterior petal lobes ca. 4.5-5.5 mm long, anterior petals ca. 21-23 mm long, anterior petal lobes ca. 6-7 mm long, predominantly violet-blue; abaxially hairy, hairs evenly spread. Stamens dissimilar in length, exserted in adult flowers; anthers dorsifixed; filaments shortly adnate (<5 mm) above staminal scales. Staminal scales inserted well below the throat of the corolla tube, 2.5 mm above the base of the corolla tube, reduced to ridges, rounded, lateral lobes wanting, villous, area between scales also hairy. Style median sections hairy. Mericarpids narrowly ovoid-trigonous; tuberculate; hairs absent; lateral ridges prominent; dorsal side acute; dorsal keel inconspicuous; ventral keel inconspicuous to prominent.
