The var. Donnellii is simply a xerophytic condition in 
which the leaves fall off and the terminal branches become 
brittle, thus propagating the species; in fact, the fruit is seldom 
found. Austin and J. D. Smith collected it at Caloosa, Florida, in 
1876-78 and Mr. Severin Rapp has reported it from Sanford. In 
all our Jamaica collections I have found it but once, on a calabash 
tree.
