3. A. zeylanlca, Mom Cat. 37 ; villous with long spreading hairs, leaf- 

 lets nearly orbicular coarsely obtusely toothed, lower bracts broad leafy, calyx- 

 tube villous deeply grooved, spines spreading. A. Eupatorium, Thwaites Enum. 

 102; jr^AiJc. t. 224. 



Cbyion, central province, at an elevation of 5-7000 ft. 



I keep up this species with great hesitation, suspecting it to be only a tropical 

 form of A. Eapatorium, and there being approaches to it amongst the Sikkim and Khasia 

 specimens of that plant ; it is however far more unlike than these to any European 

 form in the villous pubescence, short leaves and rounded leaflets. It is further re- 

 markable that neither this nor any other Jgrimonia should be found in theWestern 

 Peninsular mountains of the Indian continent.
