Doubtful and excluded species 



AsEMELA CARNEA Raf. New Fl. 4: 88. 1S38. 



Badiera Berteriana Spreng. Syst. 3: 172. 1826. Polygala domingensis Bertero; 

 Spreng. Syst. 3: 172, as synonym. 1826. Not P. domingensis Jacq. 1780. Hispaniola, 

 Bertero. Not identifiable from description. 



Polygala acuminata Willd. Sp. PI. 3: 887. 1803. This South American species was 

 wrongly attributed by Willdenow to Mexico. 



Polygala adenophylla St.-Hil. The specimen recorded by Bennett (Jour. Bot. 17: 202. 

 1879) under this name is P. subalala S. Wats. 



Polygala Americana angustifolia viridula Kuntze, Rev. Gen. 48. 1891. 



Polygala axillaris Poir. in Lam. Encyc. 5: 489. 1804. This species, wrongly described 

 as from the Antilles, is the Indian Floscopa axillaris (Poir.) Clarke. 



Polygala Berteriana DC. Prodr. 1: 328. 1824. Santo Domingo, Bertero. According 

 to St.-Hilaire, this is P. hygrophila H.B.K.; that species, however, is not known from Hispan-
