80 FLOKA OF JAMAICA Pterocarpus 



Linnaeus {loc. cit.) gives no diagnosis, lie merely refers to his Mat. 

 Med. 522 and Jacq. Hist. 283, t. 183, f. 92. Pterocarpus of the Mat. Med. is 

 based on Hermann's PI. Zeyl. 417, of which there are two specimens in 

 Hermann's Herb., both of which, as Trimen pointed out, are Derris 

 uliginosa, an Old World species ; Jacquin's name applies to the American 

 species, and also has priority over P. Draco L.
