Lobostemon collinus Schltr. ex C.H.Wright

Resprouting shrub, 20-40 cm high. Branches caulous, antrorse, herbaceous branches hairy, woody branches glabrescent. Leaves herbaceous, cauline, transversely incurved to recurved, longitudinally straight to slightly naviculate, dead basal leaves not persistent, (10-)18-25(-30) x (1.5-)2.0-3.0(-4.0) mm, oblong, adaxially glabrous to sparsely hairy with age, hairs unevenly spread, largely confined to margin, apex and mid-vein, abaxially glabrous to sparsely hairy with age, hairs unevenly spread, largely confined to margin, apex and mid-vein, indumentum spinous, appressed or umbonate, hairs similar in length, trichomes pustular; leaf margin entire; apex 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 (5-)6-12(-14) x (1-)2-4(-6) mm, ovate. Flowers small (anterior petals 17-30 mm long), more than three per cymule, funnel-shaped. Sepals narrowly oblong to lanceolate, more than half of corolla length, dissimilar in width, free, adaxially sparsely hairy, hairs unevenly spread across the whole surface, largely confined to margin and apex, abaxially sparsely to copiously hairy, if sparsely hairy then hairs more or less evenly spread across the whole surface, if copiously hairy then 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. 12-13 mm long, posterior petal lobes ca. 3.5-4 mm long, anterior petals ca. 13-14 mm long, anterior petal lobes ca. 4.0-4.5 mm long, predominantly light violet-blue; abaxially hairy, hairs unevenly spread, largely confined to the mid-veins and lobes. Stamens dissimilar in length, slightly 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, 1-2 mm above the base of the corolla tube, reduced to ridges, rounded, lateral lobes wanting, villous, area between scales also hairy. Gynoecium 2-carpelled; ovary superior, 4-locular (via false septa); nectariferous disc present, longitudinally convex, transversely 4-angled; Style median sections hairy. Mericarpids narrowly ovoid-trigonous; slightly tuberculate near the base and ridges; hairs absent; lateral ridges inconspicuous; dorsal side acute; dorsal keel prominent; ventral keel inconspicuous.
