(West, p. 271, mentions two species. Convolvulus matutlnus and C.vene- 

 natus, as occurring in St. Croix, and refers for their description to Vahl's 

 Symb. Bot. i)ars 3, as spec. nov. As, however, they are not described in 

 any of Vahl's publications, and no specimens are in existence in lib. 

 Ilavn., I am unable to say whether they are old species or new^ ones.)
