Lobostemon paniculiformis Dc. & A.Dc.

Resprouting shrub, 60-100 cm high. Branches caulous, antrorse, herbaceous branches hairy, woody branches glabrescent. Leaves herbaceous, cauline, transversely applanate to incurved, longitudinally straight, dead basal leaves not persistent, (10-)15-28(-32) x (3-)4-7(-9) mm, narrowly oblong to oblanceolate, adaxially glabrous to sparsely hairy, hairs more or less evenly spread, abaxially copiously hairy, indumentum spinous and umbonate, hairs similar in length, trichomes simple or pustular; leaf margin entire; apex obtuse; mid-vein abaxially unobtrusive. Inflorescence of many flowered, compound cincinni, young flowering axis compact, flower buds arranged in two distinct parallel rows, spreading slightly in fruiting stage. Bracts (6-)8-24(-26) x (2.0-)2.5-5.0(-7.0) mm, oblanceolate. Flowers small (anterior petals 17-30 mm long), more than three per cymule, funnel-shaped. Sepals linear, less than to half of corolla length, dissimilar in width, free, adaxially sparsely to copiously hairy, if sparsely hairy then hairs more or less evenly spread across the whole surface, abaxially copiously hairy, non-velutinous; young apices applanate, brown trichomes on the adaxial surface wanting. Petals dissimilar, the anterior petal lobes larger than the rest, posterior petals ca. 10-11 mm long, posterior petal lobes ca. 2 mm long, anterior petals ca. 13-14 mm long, anterior petal lobes ca. 3-4 mm long, violet-blue; abaxially glabrous. Stamens dissimilar in length, exserted to included in adult flowers; anthers dorsifixed; filaments free from petals to shortly adnate (< 5 mm) above staminal scales. Staminal scales inserted below the throat of the corolla tube, 3.8-4.0 mm above the base of the corolla tube, usually well-developed, triangular, lateral lobes present, 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.
