Obs. Of this genus I have examined four species. 

 Two of these are unpublished plants ; the third 

 is Asclepias lactifera Linn,, of which there is 

 no specimen in the Linnean Herbarium : it 

 therefore rests entirely upon Hermann's speci- 

 mens, which, though collected 140 years ago, 

 were by maceration in water so far recovered, 

 as to enable me with certainty to determine 

 its genus. The fourth is Periploca sylvestris, 

 IVilld.sp.pl. 1. p. 1253.
