Brunia macrocephala Willd.

About 60 cm high, with densely puberulous branchlets. Leaves mostly 0.7-1 cm long, imbricate, oblanceolate-linear, subacute, erect-spreading, incurved, convex on the dorsal surface, bisulcate on the ventral surface, densely and shortly pubescent on both surfaces, villous-ciliate. Flower-heads about 2.5 cm wide, globose, involucred by lanceolate leaves. Bract lanceolate, subacute, attenuate at the base, mostly pubescent on both surfaces, villous-ciliate, densely villous at the base, reaching to near the tips of the petals. Calyx-tube narrowly obconic, densely villous: calyx-lobes spaced at the base, 3-4 mm long, acicular, densely villous on the dorsal surface. Petals about 5 mm long, acicular, widened above the middle into an elliptic obtuse lamina at the base of which arise 2 long-decurrent wing-like keels, glabrous. Stamens much exserted: filaments unequal in length (one much shorter than the others); anthers 2 mm long, linear-oblong; thecae free 1/2 their length. Ovary almost entirely inferior, villous on the upper part, with 2 imperfectly formed biovulate chambers (placentas with the inner edges united in the lower half, free in the upper half): ovules at even height, pendulous: styles villous at the base. Fruit unknown.
