ON THE ASCLEPIADEJE. 



link between the gtrue Asclepiadeae, and the 

 Periplooeae, which follow. I have examined 

 five species, of which two are published plants, 

 viz. Periploca secamone Linn, and emetica of 

 Retz. and Willdenow. The third is a climber, 

 a native of India, discovered by Dr Roxburgh ; 

 and two are erect shrubs, natives of the tro- 

 pical part of New Holland.
