Olinia cymosa extends from the Cape Peninsula along the coastal belt ag far as the 
Kei mouth, beyond which we have no record of its occurrence. MacOwan collected the 
species at Somerset East, which is the only record of its inland occurrence. 
Olinia radiata. Is found in the Pondoland forests and extends as far as Ingeli in 
Natal. 
Olinia acuminata. This is an inland species. The most southern record is at Queens- 
town, and from there it extends to the slopes of the Drakensberg in East Griqualand to 
the mountainous districts of the eastern Transvaal (Barberton), and occurs again in the 
Woodbush Forest in the Pietersburg District. An outlier of the species is recorded from the 
Magaliesberg in the Transvaal. 
The flowers are largely infected by a Hemiptera larva which appears to arrest their 
development, which is reflected in the length of the calyx-tube. In some specimens the 
calyx-tube is much longer than the petals, i in other it equals the petals, while specimens 
are found in which the calxy-tube is shorter than the petals. All gradations are found 
even on the Same specimen. 
Two specimens of O. cymosa differ slightly from the other specimens of the species 
examined in that the petals are rounded at the apex and not bluntly pointed (Kast London, 
Rattray 849, Somerset East, Bolus 1772), but in specimens collected by Flanagan near the Kei 
mouth both forms of petals occur,

Olinia cymosa, Thunb., “Flora Capensis,” 194. (Plate I.) 
Branches glabrous. Leaves 3°7 em. long, 1-3°5 em. broad, lanceolate, obovate, elliptic, 
acuminate, obtuse, sometimes rounded at the apex, narrowed at the base into a distinct 
petiole, margins entire, sometimes wavy, glabrous, green and shiny above, paler beneath. 
Inflorescence axillary, a dense trichotomous cyme, very much shorter than the subtending 
leaf. Bracts opposite. same length as the flowers, often deciduous. Penduncles minutely 
pubescent. Calyx-tube 1-6 mm. long, glabrous or minutely hairy with ftve minute teeth. 
Petals five, inserted at the throat of the tube, about one-third the length of the calyx, 
rarely equalling it, spathulate, acute or obtuse at the apex, with a cluster of hairs at the 
base. Scales five incurved, alternating with the sepals, minute, obovate, densely hairy. 
Stamens five, adnate to calyx below the scales ; filaments very short. Ovary inferior, five- 
celled, with three pendulous ovules from a central placentum i in each cell; style subulate ; : 
stigma obtuse. Fruit globose, 1 cm. in diameter.—‘ Flora Capensis,” I, 520, Exel. var.
