fl. and fr. March 1855 and beginning of June 1856. No. 381- A 

 variety with the bracteoles and flowers green not reddish. At 

 Mussengue together with the typical plant ; fl. Dec. 1856. No. 3816. 

 ' The negroes call this plant " Risanza," and the Portuguese colonists 

 •call it " Casaogao." The failure in rearing horned cattle in Golungo 

 Alto is said to be due principally to the frequent presence of this 

 terrible stinging plant ; Welwitsoh, however, doubted this statement ; 

 it probably causes cattle to avoid the pastures in the same way as does 

 Lepistemon africanum Oliv. See ante, pp. 723, 731.
