‘Some of the most important specific characters being derived 
from the seed, it is difficult to determine several of the species 
in a flowering condition. The following key based on leaf- 
characters may be of assistance in such cases, At the same 
time it should be pointed out that the lobing and serration of 
the leaves appears to be less constant than the shape and 
indumentum of the seeds.
