Acacia cyclops [family FABACEAE]
A. cyclopis A. Cunn. ex Loudon, Hort. Britt. 407 (1830) nomen nudum.
Unarmed shrub or small tree up to 6 m high; young branchlets usually angular and glabrous. Leaves phyllodic, apparently simple, glabrous, 3-9 x 0,6-1,5 cm, narrowly-oblong, usually Â± straight, someÂtimes slightly falcate, obliquely mucronate apically, narrowed basally, with 3-5 promiÂnent longitudinal nerves and anastomosing almost longitudinal veins. Inflorescences gloÂbose, solitary or two or three in short axillary racemes. Flowers bright yellow; peduncles up to 7 mm long. Calyx pubescent apically, more than half as long as the corolla. Petals free. Pods brown, 5-15 X 0,8-1,3 cm, oblong, falcate or variously coiled or spirally twisted, flattened, margins not constricted between the seeds, dehiscing longitudinally along both margins. Seeds dark brown, 5-7 x 3-4 mm, smooth, compressed; areole Â±4x2 mm; funicle thickened, bright red or orange, encircling the seed in a double fold.
Like A. saligna, A. cyclops was introduced on the Cape Flats in the 1870's in an attempt to stabilize the shifting dune sands. It proved highly successful for this purpose and soon started spreading by natural means. A. cyclops is now found far beyond the area of the Cape Flats and has become a serious menace in many parts of the Cape Peninsula and on the mainland by invading and displacing the indigeÂnous vegetation. In many areas A. cyclops occurs in dense almost impenetrable stands.
