Habitat .- Natal : Coast districts, Clairmont 50 feet alt., October, Wood No. 

 1,154; Umlaas, March, Wood No. 876; Umkwahumbi, April, Wood. 



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



This genus includes about 26 species, all natives of South Airica except two, 

 which are found in Madagascar, and one whose native country is not certainly 

 known, some of them like the one here described are well worth cultivation, and 

 several have been introduced into Europe, the flowers of most, if not of all, of the 

 species are pink or purplish. This plant was formerly known as Plocandra pur- 

 purascens, E.M., the generic name having been given on account of the peculiarly 

 twisted anthers, but the genus Plocandra is now merged in Chironia.
