able to find a constant character on which they can be separated into 

 groups. . Two specimens (not in flower) collected by Galpin on the 

 mountain -tops at Queenstown at an altitude of 4700 ft. (Galpin 

 2560 & 2561) differ from the other specimens examined in the leaves 

 being more or less membranous. This however, as pointed out by 

 Mr. Galpin himself, is probably due to the altitude and the fact that 

 the specimens were growing in the shade of rocks and almost pros- 

 trate on them. The material of the specimen (^. <Sf Z. 923) which 

 Harvey names Xavthoxylon? alatum is very poor and leaves one in 

 doubt as to whether it belongs to the genus, especially as Xantho- 

 xylon does not appear to be represented in the western parts of the 

 Cape Province.
