Peperomia scandens R. & P. is recorded by C. de Candolle as 

 found by Friederichsthal on St. Thomas (Prodr. 16 1 : 434, 1869); 

 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).

Peperomia Rupertiana C. DC.(?) Wet, shaded bank, Rosen- 

 berg, St. Jan. Determined from a barren specimen, and identification 

 therefore doubtful.
