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

 Convolvulus Tuba, Schlecht. in Linncea, 1831, p. 735. — Calonyction 

 grandiflorum, Choisy, Conv. Or. p. 60; DO. Prodr. ix. p. 346. 



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 u Salso da Praia " here. 



Distribution. Antilles, Surinam, and Guiana ; but it does not 

 appear to be known from 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.
