362 LT. ROSACE JE. (J. D. Hooker.) [Agrimonia. 



3. A. zeylanica, Moon 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; Wight Ic. t. 224. 



CEYLON, 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. Eupatorium, and there beingxapproacb.es 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 Agrimonia should be found in the Western 

 Peninsular mountains of the Indian continent.
