Resprouting shrub, 60-100 cm high. Branches caulous, antrorse, herbaceous branches hairy, woody branches glabrescent. Leaves herbaceous, cauline, transversely applanate, longitudinally straight, dead basal leaves not persistent, (28-)30-45(-60) x (2-)3-5(-6) mm, oblanceolate, adaxially and abaxially sparsely hairy, hairs more or less evenly spread, indumentum umbonate, hairs similar in length, trichomes simple or pustular; leaf margin entire; apex acute; 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 (1-)2-3(-4) mm, lanceolate to oblanceolate. Flowers medium sized (anterior petals 17-30 mm long), more than three per cymule, funnel-shaped. Sepals narrowly oblong, more than half of corolla length, dissimilar in width, free, adaxially sparsely hairy, hairs unevenly spread, largely confined to margin, apex and mid-vein, abaxially sparsely hairy, hairs unevenly spread, largely confined to margin, apex and mid-vein; young apices incurved to applanate, brown trichomes on the adaxial surface wanting. Petals dissimilar, the anterior petal lobes larger than the rest, posterior petals ca. 18-19 mm long, posterior petal lobes ca. 2.5-3.0 mm long, anterior petals ca. 19-20 mm long, anterior petal lobes ca. 4 mm long, predominantly creamy yellow; abaxially glabrous. Stamens dissimilar in length, mostly 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, 3.5 mm above the base of the corolla tube, well-developed, rounded, lateral lobes wanting, villous, area between scales also hairy. Style median sections hairy. Mericarpids ovoid-trigonous; apex rounded, tuberculate; hairs absent; lateral ridges prominent; dorsal side acute; dorsal keel prominent; ventral keel inconspicuous.
