(H. molle Dicks., van maximum Boul. Muse. Fr. ). The form of tiie leaves is 

 the same, and this is the principal character used for separating from it H. dila- 

 tatum Wils. and H. alpinum Sch. These latter species intergrade with each 

 other and with H. molle by numerous transitional forms poorly delimited, so 

 that one can not consider them as distinct species. The case stands the same 

 with * H. Bestii Ren. et Bryhn, which allies itself with the type of H. molle 

 Dicks, rather than with H. dilatatum and H. alpinum, but which is distinct by 

 its general make-up, its loosely-set leaves, the areolation a little more loose and 

 the middle cells longer (60-90//, while in H. molle they are 40-70 /i), 



" A form collected in 1884 by Dr. Jeanbernat in the Pyrenees had struck me 

 by its peculiar appearance, differing from all European or American specimens 

 of H. molle which I have been able to see, and had labeled in my herbarium 

 ' H. molle Dicks, forma insignis.' Its form is a little less robust, the leaves are 

 smaller, the costa is less strong than in the plant from Montana; but one finds 

 here again the same distinctive appearance (port), the leaves less crowded, 

 spreading, the areolation more lax and the cells in the middle of the leaf long 

 and rather pointed. It ought to be placed as a variety with * H. Bestii Ren. et 

 Bryhn. 



"Var. Pyrenaicum Ren. In appearance very similar, but of smaller size, 

 leaves smaller, costa a little shorter, less stout. 



" Hab. Pyrenees, Lac de Camporeil, Capsir, alt. 2200 m., leg. Dr. Jeanber- 

 nat, 1883."
