Ipom(ea Tuba, G. Don, Syst. iv. 271 (1837) ; Meissn. in Mart. 

 Fl. Bras. vii. p. 216.— I. grandiflora, Lam. III. i. 467 (1791).—

Forms a large densely matted bed covering the rocky debris in 

 Chaloupe Bay, where the stems attain a thickness of nearly 

 2 inches and a considerable length, exuding a copious white 

 latex when cut. It is almost equally abundant on a slope at 

 the base of the Peak ; and occurred also on Platform Island. 

 This is called " Salso da Praia" here. 



Bistribuiion. Antilles, Surinam, aud (xuiana ; but it does not 

 appear to be known fi-om Brazil except from this locality. It 

 was only found on the north side of the island, and probably the 

 seeds were drifted on to the island from the north.
