normal examples droop, and frequently touch the ground; its fruits are. 
fewer. 
As an illustration I append a table to show the differences between 
the measurements of the length and breadth of the normal form and 
what I must consider a new sub — species.

These two instances are typical for the forms in question. I may 
here state that in the subspecies the leaves gradually narrow towards 
each extremity, whilst in the normal species they are nearly oval. The 
small and oval leaves do not occur on the same tree. The brown hairs 
on the under surface of the leaf are not constant, and therefore cannot 
be relied on as characters.
