Leaf-Shape. 



There is a considerable range of variation in the form of the leaf in 

 Primula sinensis. Besides the common palmate and fern-leaf varieties, 

 Messrs Sutton have raised a strain in which the peculiar lobing of the 

 leaf is repeated in the petals, which also .somewhat resemble the leaf in 

 formi. Of other types, the Ivy-leaf is described below ; while I have 



1 Roy. Hurt. Sue. Jniirii. Vol. xxxv. Pt. i. 1909, p. xxxvi. The leaves of this variety 

 are described as approaching those of Ivy ; it may be well, therefore, to point out that the 

 character is a different one from that of the strain to which I have applied the name of 

 " Ivy-leaf" in this paper.
