Names
Vernonia albocinerascens C. Jeffrey [family COMPOSITAE], in K.B. 43: 222 (1988). Type: Uganda, Karamoja District, Mt Moroto SE foothills, Tweedie 2643 (K!, holo.)
Information
Woody herb or shub 0.9-4.5 m high, much-branched, with several virgate stems; branches at first densely white-tomentose with short T-shaped hairs, older stems with rough grey longitudinally fissured bark. Leaves aromatic, grey-green, obovate, 0.8-4 cm long, 0.3-1.7 cm wide, base cuneate or attenuate, margins obscurely sinuate-denticulate in upper part, apex rounded, apiculate, finely shortly pubescent, densely glandular with sunken glands. Capitula numerous in rather dense compound corymbiform cymes; involucre cylindrical to obconic, 3-5 mm long, 1.5-2.5 mm in diameter at flowering time; phyllaries 4-seriate, pale green, darker green centrally towards the apex, ovate to elliptic, 1-4.7 mm long, obtuse or the inner sometimes acute, apiculate, ciliate on margins. Flowers fragrant; corolla white, tube 3.9-4.7 mm long, lobes 1.5-2.5 mm long, glabrous. Achenes strongly 4-6-ribbed, 2-2.9 mm long, short ascending-pubescent; outer pappus of narrowly lanceolate laciniate scales, 0.5-1.2 mm long, inner pappus white, 3.5-5.5 mm long.

Notes
Described by C. Jeffrey as close to V. cinerascens and easy to confuse with that species, but differing in the denser inflorescence with more capitula, and with the corolla always white.
