Lobostemon decorus Levyns

Resprouting shrub, 60-100 cm high. Branches caulous, antrorse, herbaceous branches hairy, woody branches glabrescent. Leaves herbaceous, cauline to acroramous, transversely applanate, longitudinally straight, dead basal leaves not persistent, (20-)40-60(-65) x (2-)3-4(-5) mm, narrowly oblong, adaxially sparsely hairy, hairs more or less evenly spread (but often appearing glabrous), abaxially sparsely hairy, hairs more or less evenly spread, indumentum spinous, hairs similar in length, trichomes simple or sometimes 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 (8-) 10-12(-14) x (1.0-)1.5-2.0(-3.0) mm, narrowly oblong. Flowers medium sized (anterior petals 17-30 mm long), more than three per cymule, funnel-shaped. Sepals narrowly oblong, half to slightly more than half of corolla length, similar in width, free, adaxially sparsely hairy, hairs more or less evenly spread across the whole surface, abaxially sparsely hairy, hairs more or less evenly spread across the whole surface; 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. 21-22 mm long, posterior petal lobes ca. 4 mm long, anterior petals ca. 23-24 mm long, anterior petal lobes ca. 4.5-5.0 mm long, predominantly violet-blue; abaxially hairy, hairs evenly spread. 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, 4.5-5.0 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 broadly ovoid-trigonous; smooth; hairs absent; lateral ridges inconspicuous; dorsal side vertical; dorsal keel prominent; ventral keel prominent.
