Sabbatia macrophylla Hook. Comp. Bot. Mag. I : 171. 1835 



Grows in a sphagnous bog north of Americus, at an altitude 

 of about 350 feet. It is accompanied by Sarracenia rubra, S. 

 Drnmmondii, Pogonia ophioglossoides, Poly gal a crnciata ranwsior, 

 P. lutea, etc., and flowers in July. This is probably the highest 

 known station for this species. It has been previously reported 

 only from near the Gulf coast. 



Sabbatia decandra (Walt.) 



Chironia decandra Walt. Fl. Car. 95. 1788. 



Sabbatia chloroides var. erecta Ell. Bot. S. C. & Ga. I : 286. 



1817. 



Sabbatia chloroides var. stricta Griseb. Gen. et Sp. Gent. 125. 



1839; also in DC. Prodr. 9: 50. 1845. Gray, Syn. Fl. N. A. 



115. 1886. 



Sabbatia dodecandra stricta Mohr, Bull. Torr. Club, 24 : 26. 



1897. 



Although Walter's description of this species (" flor. decem- 



fidis colore dodecandrae, foliis linearibus, caule rigido erecto ") is 

 rather brief, still there is no other known plant in the southeastern 

 states which answers it exactly, and as his name for the species is 

 cited as a synonym by both Elliott and Grisebach, no hesitation is 

 felt in taking it up here. 



That it is a species distinct from. 5. dodecandra (L.) B.S.P. (5. 

 chloroides Pursh) there can be no doubt after comparing specimens 

 of the two. One important and apparently constant distinguish- 

 ing character, which seems to have been hitherto overlooked, is 



found in the calyx-segments. These in 5. decandra are semicir- 

 cular in cross-section, and awl-shaped, while in 5. dodecandra they 

 are flat, and of about the same width from the base to near the apex. 

 S. decandra is one of the most beautiful and conspicuous plants of 

 the wet pine-barrens of Sumter County, where it flowers in July 

 and August. Besides my own specimens, collected July 21, 1897, 

 the following in the herbaria of Columbia University and the New 

 York Botanical Garden, all from Florida, are referred here :
