Aspalathus angustifolia (Lam.) R.Dahlgren

An ascending, erect, or decumbent shrub or shrublet, 0.15-0.5 m (subsp. robusta up to elm) tall, sparingly branched or virtually unbranched, branches often radiating from a short basal stem. Young branches usually slender, straight or ascending, weak(-rigid), glabrous or occasionally with sparse(-close) long, spreading hairs. Leaves sparsely or closely distributed, linear to broadly lanceolate, 10-35 x 1-6 mm, rigid, sharply spine-tipped, straight, green, glabrous (or occasionally with scattered long hairs on margins), lower side with 3-5 prominent veins beside the marginal veins, upper side ± smooth; margins smooth. Inflorescence unifloral or a terminal raceme or umbel of 2-6 flowers; flowers attached nearly on one point or at a short distance from each other on a common, non-pedunculate or rarely peduncle-like axis. This sometimes pushed aside by a rapidly growing branch in the axil of the upper-most leaf. Bract small, weak, subulate or acicular, less than 3 mm long, narrow, glabrous (or ciliate). Pedicel 2.5-10 mm long, usually glabrous, rarely white-woolly. Bracteoles less than1.5 mm long. Calyx tube narrowly campanulate-cylindrical, 5-6 mm long, glabrous (rarely sparsely long-hairy), veiny; lobes lanceolate or very narrowly triangular, 3.5-8(-11.5) mm long, acuminate or spine-tipped, green with 3distinct veins, glabrous; the upper most two lobes united (dorsally) further than the others. Petals bright yellow(-partly reddish), wing and keel claws ±50 % and 66 % of the blade.

It is a subtropical plant. In South Africa it grows between 260-460 m above sea level.
