In Georgia I have seen this in flat damp pine-barrens in Mcln- 

 tosli (especially around Darien Junction), Glynn, and Brooks {jio. 

 16 J i) counties. In Alabama Dr. Mohr reported it from Mobile 

 and Baldwin counties, in various situations varying from moist 

 pine-barrens to brackish marshes. (Dr. Chapman gave brackish 

 marshes as its only habitat.) Specimens examined show it to 

 range southward to the Everglades of Florida and westward to 

 Louisiana. 



^ Mesadenia lanceolata virescens var. nov. 



Stem 9-10 dm. tall ; leaves yellowish-green on both surfaces, 

 not glaucous, the lowest 16-1S cm. long. Otherwise much like 

 M. lanceolata. 



Apparently confined to the Altamaha Grit region of Georgia, 

 where it grows in moist pine-barrens, with both Lafa}'ette and 

 Columbia formations present. Flowers in September and Octo- 

 ber. It is represented in my collections by 110. 66.^, collected 

 September 19, i900,t and no. i6j8, collected September 26, 

 1902, both from Tifton, Berrien county. I will designate no. 

 idyS as the type because I have distributed more specimens of 

 it than of the earlier number, but the two collections are abso- 

 lutely identical, their stations being only a few feet apart. 



I have noted the same plant also in the counties of Dodge, 

 Telfair, Appling, Coffee, Wilcox, Irwin, Dooly, Worth, Colquitt 

 and Thomas ; and I have little doubt that it grows also in Bul- 

 loch, Emanuel, Tattnall and Montgomery, which counties I have 

 not yet visited at the proper season for identifying it. Jackson's 

 plant mentioned by Elliott, if it is the same as mine, probably 

 came from Emanuel County.
