 dots brown (black when dry), sunk in the substance of the leaf, chiefly confined to 

 the margin, occasionally on the surface of the lamina, sometimes absent ; 4-5 lines

Drawn and described from a plant which flowered in the Botanic Gardens, 

 Durban, October, 1900. 



This plant was formerly known as Melanosticta Sandersoni, but the genus is 

 now united to Hoffmanseggia. Two species only of the genus are found in South 

 Africa, the one here described, and M. Burchellii, which was found in Zululand, 

 and is also a native of Tropical Africa, while Hoffmanseggia Sandersoni so far 

 as known to us has only been found in Natal and Transvaal. The roots have 

 been used for tanning leather, and the juice of the roots is said to be useful as an 

 application to horses backs when chafed by the saddle.
