Resprouting shrub, 60-100 cm high. Branches caulous, antrorse, herbaceous branches hairy, woody branches glabrescent. Leaves herbaceous, acroramous, transversely incurved, longitudinally straight, dead basal leaves not persistent, (21-)25-50(-60) x (3-)4-5(-5.5) mm, lanceolate to oblong, adaxially sparsely or 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, hairs similar in length, trichomes simple or pustular; leaf margin entire; apex acute or obtuse; mid-vein abaxially prominent. Inflorescence of many flowered, compound cincinni, young flowering axis compact, flower buds loosely arranged to form a globose unit, spreading slightly in fruiting stage. Bracts (10-)12-17(-18) x (2.0-)2.5-3.5(-4.0) mm, lanceolate. Flowers medium to large (corolla 15-25 or > 25 mm long), more than three per cymule, funnel-shaped. Sepals narrowly oblong to lanceolate, less than half or half of corolla length, almost similar in width, free, adaxially and abaxially copiously hairy, non-velutinous; young apices mostly incurved to applanate, brown trichomes on the adaxial surface present. Petals dissimilar, the anterior petal lobes larger than the rest, posterior petals ca. 22-23 mm long, posterior petal lobes ca. 4.5-5.0 mm long, anterior petals ca. 24-25 mm long, anterior petal lobes ca. 4.5-5.0 mm long, predominantly deep violet-blue; abaxially hairy, hairs evenly spread. Stamens dissimilar in length, included in adult flowers; anthers dorsifixed; filaments shortly adnate (<5 mm) above staminal scales. Staminal scales inserted well below the throat of the corolla tube, 4-5 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 ovoid-trigonous; tuberculate; hairs absent; lateral ridges prominent; dorsal side acute; dorsal keel prominent; ventral keel inconspicuous.
