C. V. Piper bases his name for the species on the supposed identity of 

 Linnseus's original specimen of Dolichos unguiculatus with the plant 

 described by Urban as Phaseolus antillanus, but there is no specimen so 

 named by Linnpeus in his Herbarium, nor from the evidence of his own 

 lists does it appear that there ever was one. Further there is no specimen 

 that agrees with Phaseolus antillanus Urb.
