Plant._ vol. i. p. 658. * * * * * =Cotyledon Wickensii=, _Schonl. in Records Albany Museum_, vol. iii. p. 141. * * * * * The _Pillansii_ group of _Cotyledon_ as defined by Dr. Schönland includes species with a suffructicose, mostly robust habit, with the lobes of the corolla usually longer than the tube, glandular flowers, and with a tuft of hairs at the base of the filaments where they join the corolla. The species figured here was collected by Mr. J. Wickens and Dr. I. B. Pole Evans, C.M.G., on stony kopjes at Smit’s Drift, in the Pietersburg District of the northern Transvaal. It is well adapted for rockeries, and flowers profusely during the mid-winter months of June and July. The species has been established in the rockeries of the Union Building gardens at Pretoria, and is doing remarkably well. Our plate was prepared from specimens growing at the Division of Botany, Pretoria.
