The Indian plant is identical with that of Europe, and varies in the same way m 

 the degree of dentation and in size, being very luxuriant at moderate elevations, and 

 becoming small and stunted at its highest level. The white-flowered variety is I 

 remarkable one, but it is undistinguishable in the herbarium.

 scarcely be united, even if the floral organs were the same in all respects ; wh ,1s .the 

 insertion of the ovules in Calathodes is so remarkable, that no doubt can exist as to 

 the propriety of distinguishing it generically.
