Richardsoxia sgabra St. Hil. PI. Us. Bres. 7 : pi. 8 

 Not rare in sandy waste places and cultivated fields, Americus. 



Pinckneya pubens Mx. Fl. Bor. Am. i : 105.//. rj. 1803 



This unique and interesting shrub is quite common in non- 

 alluvial swamps in Sumter County, and flowers in June and July. 

 It has not previously been reported so far from the coast or at so 

 high an altitude. 



Viburnum dentatum L. Sp. PI. 268. 1753 



Grows in a swampy place near Barlow's Mill, Sumter County, 



where it flowers in September. This seems to be its southern 

 limit. 



Lacinaria elegans (Walt.) Kuntze, Rev. Gen. PI. 349. 1891 



In dry sandy soil east and west of Americus, flowering in Au- 

 gust and September. According to my observations the corollas 

 in this species are invariably pure white, a fact which does not seem 

 to have been noted before. 



Aster adnatus Nutt. Jour. Acad. Phila. 7: 82. 1834 



Not rare in moist pine-barrens east of Huntington. Previously 

 known only from Florida and Alabama. The flowers of this 

 species must be very late, for no trace of them is visible at the 

 end of August. 



Rudbeckia Mohrii Gray, Proc. Am. Acad. 17: 217. 1882 



R. bupleuroides Shuttl.; Chapm. Fl. S. States, ed. 2, 629, 

 1883. 



One of the characteristic plants of moist pine-barrens in the 

 southeastern part of Sumter County, flowering from June to the end 

 of August. This makes the third known station for this species, 

 the other two being in West Florida, about 125 miles farther 

 south and 200 feet lower. 



Helianthus Radula (Pursh) T. & G. Fl. N. A. 2 : 321. 1842 



In moist pine-barrens, flowering in September. Sumter Count}- 

 seems to be its northern limit, as far as known.
