1 In his presentatiou of the Ammlaceae in Hooker, Flora of British 

 India. II 703. C. B. Clarke regards Pterocyclus as not generically 

 distinct from Pleurospermum. The last genus appears to be properly cha- 

 racterised as containing forms which have the fruits conspicuously flattened 

 laterally and the flat, depressed stylopodia. On the other hand, by Ptero- 

 cyclus the fruit is „dorsally compressed" and, according to the figure by 

 Klotzsch und Garcke, Botan. Ergebn. d. Reise Prinz. Waldem. t. XLYII, 

 fig. d,, the stylopodium is evident conical.
