Jennings: Contribution to Botany of Isle of Pines. 117 



1910, 0. E. Jennings, No. 44Q. General Distribution: Heretofore 

 known only from the Miami River in southern Florida. 



The specimens show the straight-sided, A-shaped sinus, at the 

 base of the leaf, and the bright red stigmatic surface which characterize 

 the variety and distinguish it, also, from the common NymphcBa 

 americana (Provancher) Miller & Standley of the eastern United 

 States.

This is the more tomentose plant which, by many botanists, is 

 regarded as merely a form of Cissampelos Pareira Linnaeus, distributed 

 widely through the West Indies and the tropics generally. Blain's 

 No. 52, from the northern part of the Isle of Pines, is reported by 

 Millspaugh (Field Columb. Museum, Bot., I, 1900, p. 427) as C. 

 Pareira.
