REVISION OF EXTRA-TROPICAL SOUTH-AFRICAN 

 ASCLEPIADACEiE. 



By Rudolf Schlechter. 



(Concluded from Journ. Bot. 1897, p. 295.) 



It is with some hesitation that I piibhsh this list of Stapeliem. 

 However, it had to be done. But I hope that, incomplete as it may 

 be, it will at any rate throw some light upon several species. 

 Besides, having begun to pay more attention to this group than 

 I had formerly occasion to do, I hope to find leisure to study them 

 more carefully, and in a future time to give a more full account of 

 them. 



Unfortunately, my views of species seem to differ widely from 

 those of Mr. N. E. Brown, of Kew ; but although I believe him 

 a most careful worker, I fear that many of his species, when 

 he has seen more material, will have to be united with older 

 ones.
