396 Gleason : The pedunculate species of Trillium 



Type locality : South Carolina. 



Distribution : North Carolina and Tennessee to Georgia and 



Alabama. 



19. Trillium affine Rendle, Jour. Bot. 39: 334. 1901 



Type locality and distribution : Georgia. 



No specimens have been seen which could be referred to this 

 species, but Rendle's careful description makes it certain that it is 

 quite distinct from T. Catcsbaci. 



Species dubiae 



The following species were all described by Rafinesque, with 

 usually very imperfect characterizations. Accurate identification 

 of them from the descriptions alone is impossible, although his 

 statements as to the color of the petals make it probable that most 

 of them refer to T. crcctum or to T. cernuum.
