Lemon Group. 79 



ling forms, and the adult forms, grown under different 

 conditions of soil and climate, would also require to be 

 learnt, in order to obtain an accurate notion of their 

 affinities. The specimens given on pis. nos. 209 to 

 214 do not, I think, belong to this group. The 

 " Sadaphal " appears to be a distinct thing from all the 

 rest. Some which I included in this group may not 

 impossibly be varieties of the lime proper. 

 Pis. 178 to 224 give figures of this group.
