 and 33; a low clambering shrub, on soil derived from coralline lime- 

 stone, between Bogarona and Caleta Grande, May 22, 1910, 0. E.

 Cuba and the Isle of Pines. 



This species is remarkable for the great variation in the shape of 

 its leaves. In the savannas and open woods of the northern part 

 of the island it grows as a low shrub with oval, oboval, or oblong 

 leaves, while in the southern part of the island, on the coralline lime- 

 stone of the "South Coast," it grows as a vine and its leaves there 

 become very narrowly lance-oblong or even linear. The writer is not 

 yet prepared to claim that the differences noted are due to the differ- 

 ences in the soil, but our collections would seem to indicate such a 

 relationship.
