I do not think that Maximowicz's var. minor can be retained as a dis-

 is considerable variation in the size of the leaves and of the flowers and in 

 the length of the style, apparently without correlation.

With the copious material before me I am unable to distinguish between 

 var. glabrata and var. Baroniana; there are all intergradations present 

 between leaves which have the underside fairly densely covered with
