PLATE 293' 



TRIOALYSU SONDERIANA, Hiern. (Fl. Trop. Africa, Vol. 3 p. 119). 

 Natural Order, RUBIACEJ;. 



A branching shrub with white flowers, 6 to 10 feet high. Branches greyish 

 white, younger portions minutely pubescent, subangular, furrowed alternately on 

 two opposite sides, or terete. Leaves opposite, petiolate, stipulate, coriaceous, 

 glabrous, oblong to oblong-ovate or narrow-oblong, tapering to an obtuse apex, 

 and more gradually to the short petiole, margins quite entire, slightly recurved, 

 veins not conspicuous ; 2 to 3 inches long, f- to ! inch broad ; petioles thickened, 

 1 to 2 lines long ; stipules connate at base in a cup, then subulate. Inflorescence 

 axillary, cymose, cymes 3 to 8 flowered, much shorter than the leaves. Peduncles 

 very short, pedicels 3 to 5 lines long. Bracts scarious ; bracteoles 2, small, alter- 

 nate on the pedicel. Calyx gamosepalous, campanulate, 5-fid, teeth subacute ; the 

 whole calyx about 1 -line long, glabrous. Corolla gamopetalous, 5-lobed, tube 

 cylindrical, widening a little upwards, very densely hairy at throat; 2 to 3 lines 

 long, lobes often very strongly reflexed, equalling tube. Stamens 5, in throat of 

 corolla, alternate with its lobes, exserted from throat, shorter than lobes ; filaments 

 short, anthers linear-oblong, 2 celled, the connective produced beyond the cells 

 into a tongue-shaped process. Ovary inferior, 2-celled, cells 1-ovuled; style 

 elongate, stigma 2-lobed, lobes revolute, much shorter than style. Berry globose, 

 crowned with remains of the calyx, green, black when ripe, glabrous, the size of a 

 pea, 2-seeded. 



Habitat : NATAL : Coast districts; near Durban, 150 feet alt, Wood No. 1091 ; 

 also near Durban, October, Wood in Colonial Herbarium, No. 7462. 



Drawn and described from specimens gathered near Durban, April, 1902. 



In the Flora Capensis, Vol. 2, pages 22 and 23, four species of the genus 

 Kraussia. are described ; since that time two of them have been removed to other 

 genera, K. pavettoides being placed with Webera, and K. coriacea, the plant here 

 described with Tricalysia. It is a shrub reaching to 8 or 10 feet in height, and 

 bears its flowers in great abundance. No part of the plant is used in any way 

 either by natives or Europeans, so far as known to us. It is also found in Tro- 

 pical Africa.
