Mozamb. Dist. British Central Africa: Nyasaland; plateau of Mount Zomba, 
5000-6000 ft., Whyte ! 
This closely resembles 7. Bolusii, Hiern, from extra-tropical Transvaal, but 
differs in its very obtuse calyx-teeth and the form of the staminodes. 
A fragment collected on the Inyanga Mountains, Rhodesia, by Mr. Evelyn Cecil 
(209) is probably Z. pulchella, but the rich purplish-blue flowers are larger than those 
of the type.

glabrous or sparingly and minutely pubescent herb 14-2 in. high ; stem
