REPORT OF THE STATE BOTANIST FOR I92I 63 



OSTEOSPERMUM L. Sp. PI. 923. 1753 



O. Uvedalia L. is quite obviously the type of O s t e o - 

 s p e r m u m L., both in the treatment by Linnaeus and by 

 Miller (Card. Diet. 4th Abr. Ed. 1754). The Old World species 

 heretofore left in Osteospermum should be placed in 

 Monilifera Adans. (1763), or in G i b r a r i a Cass. (1817). 



Rather recently Small and Carter (Fl. Lancaster Co. Pa. 302, 

 1913) have revived the generic name Polymniastrum 

 Lam. for O . Uvedalia L., although it is antedated by 

 A 1 y m n i a Necker. P o 1 y m n i a L. as a genus can be 

 retained only if P. canadensis is regarded as generically 

 distinct from O . Uvedalia, as is done by Small and 

 Carter. The w^riter prefers to retain them both under 

 Osteospermum, 



Osteospermum canadense (L.) comb. nc>\. 

 Polymnia canadensis L. Sp. PI. 926. 1753
