60 DE. HOOKEE AND DE. THOMSON'S PE^€UESOE£S 



Bergenia group; ramulosa and imbricata; granulata, ce^-nua, and 

 odontophylla^ with possibly 8ihirica\ stenophylla Bjxd Jlagellaris i 

 hrachypoda ahd^mbriafa', jpalpebrata and cordigera ; saginoides and 

 Sirculus ; corymhosa^ diversifoUa, and latijlora ; Jacquemontiana 

 and Stella-aurea ; between some of which we find intermediate 

 specimens do occur, and between others such may be found in 



future. 



On the other hand, it would probably meet the views of those 

 who take the extreme opposite view, to extend the species founded 

 on our materials to 47, by dividing ligulata and StracTieyi each 

 into two ; the same with ramulosa^ imhricata^fiageTlaHs^ corymhosa, 

 HircuIuSy and dwersifolia. Of all these, we think the varieties of 

 StracTieyi and corymhosa best entitled to reconsideration. 



From this it appears that nearly half the forms we have examined 

 are extremely variable ; but the difficulty does not end here, for 

 of the 26 most distinct forms, upwards of half have been gathered 

 in one province alone, most of them by one individual, and in one 

 or a few spots only ; and no one can predicate the direction or 

 limits within which they will prove variable when all their forms 

 shall have been studied. 



We 



and our diagnoses 



the most prominent differential and other characters which the 

 forms present. Whatever views may be taken of the limits be- 

 tween the species, as here proposed, there can be none about the 

 certainty, that other specimens of them from different quarters of 

 the Himalaya will greatly influence their diagnoses and render 

 detailed descriptions of them worthless. What we have endear 

 voured to do, is to give a correct systematized review of the 

 genus as it is developed in India, in every case indicating the 

 forms which those who attach a different value from oiu-selves to 

 the word * species,' may combine or keep separate.
