230 Lindsey.—Branching and Branch Shedding of Bothrodendron. 
these new specimens are Bothrodendron minutifolium is not an insurmount¬ 
able difficulty, since these two species, if not identical, are at any rate very 
closely allied, and it is therefore quite probable that both had the same 
method of shedding. 
Finally, I wish to express my thanks to Dr. Hickling for his assistance 
in the preparation of this paper, and also for the photographs with which it 
is illustrated.
