Hermannia pfeilii K.Schum.

Suffrutex, much branched, 20-80 cm tall, leaf-scars prominent; branchlets thinly grey-tomentose (tomentum of fringed, minute scales and stellate hairs), glabrescent, indurating and spiky but usually not sharp-pointed. Stipules from semi-obovate to deltoid or subulate, falling by a clean cut at base or, if persisting, becoming woody and brittle, 1-3 mm long, finely stellate-pubescent. Leaves one or more at a node, very shortly petiolate; blade obovate to obovate-cuneate, often broader at apex than long, 4-15 mm long, 5-12 mm broad at apex, entire or obtusely 3-or more-lobed at apex, concolorous, sometimes conduplicate, grey-tomentose on both surfaces, tomentum of fringed, minute, pitted scales; petiole 0.5-5 mm long. Inflorescence of few-flowered, racemose cymes terminal on ultimate branchlets, flowers secund; peduncle usually indistinguishable or up to 3 mm long; bracts and bracteoles from ovate to deltoid or subulate, 1-3 mm long, rather thick; pedicels 2-6 mm long, thinly tomentose as on branchlets. Calyx patelliform, subinflated, 5-angled, from densely to sparsely finely stellate hairy without, lobed to almost middle, lobes erect, broadly triangular, sinuses wide. Petals bright yellow, about 10 mm long, blade more or less ovate, narrowed abruptly into a section with broad, incurved margins and below that into a spur which is usually curved. Stamens with broad, hyaline, obovate filaments about 3.5 mm long, apparently glabrous on the shoulders; anthers ciliate, about 3.5 mm long, overlapping the filaments for 1 mm. Ovary about 2.5 mm long, obscurely 5-lobed, finely stellate-tomentose, hairs slightly longer at the apex; stipe 0.5 mm long; styles cohering, about 4.5 mm long, shortly exserted, shortly and patently pubescent; stigmas capitate. Capsule about 5 mm long, stellate-pubescent, obtusely 5-lobed, lobes rounded at apex.
