 but in his description of West Indian Piperaceae (Urban Symb. Ant. 

 3: 229. 1902), St. Thomas is not cited. The earlier record is, pre-_ 

 sumably, erroneous.

 P. acuminata of Eggers, in part.] St. Croix, according to de Candolle, 

 collected by West; on rocks in forests, all islands (according to Eggers).
