occasion Welwitscli'fs Cabinda, while chopping off a large Poly- 

 poreous fungus (of. Fungus, n. 357) from the roots of E. TirwcalU, 

 encountered a similar accident with the milk of the latter, but 

 without any serious consequenoas. On the other hand, Monteiro, 

 Angola, ii, p. 267 (1875), states that the acrid milty juice of 

 the euphorbias is very dangerous to the eyes if it should drop 

 into them, and that the natives employ the juice of Sanseviera 

 angolensis Welw. as a remedy. 



The negroes discriminate with tolerable exactness some of the 

 species : for example, in Golungo Alto the natives call one 

 species of Croton by the name of " Mubango," and another species 

 " Mubango ia muxito," that is, " Wood Mubango " ; and in 

 Pungo Andongo a third species is called " Mubango de Cabondo." 

 Tragia corMfoUa was usually pointed out to Welwitsoh as the 

 " Casao9ao," but they called by the same name the equally 

 stinging herb Dcdecha/mpia scamdens. In a similar manner the 

 dye-plants, Alchornea cordata and Lepidotii/rus occidentaKs, in 

 Golungo Alto and Pungo Andongo respectively, are called by the 

 name of " Dunce."
