in a scientific collection. Mr. Brooks also promised to send seed later. 
Besides Mr. Brooks’s contributions Mr. Maxon received from Mr. 
Jennings 5. Cox, of Santiago de Cuba, in July, 1907, 4 photographs 
representing different views of a tree of this species, one of which is 
here reproduced.

1907, with notes furnished by Mr. Maxon, and from fruit sent by Theodore 
Brooks in 1908 from the same region,
