(West, p. 271, mentions two species, Convolrulus matut'inus and C.vene- 

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

 Symb. Bot. pars 3, as spec. nov. As, however, they are not described in 

 any of Vahl's publications, and no specimeus are in existence in Hb. 

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