ALTAMAHA GRIT REGION OF GEORGIA 227 



only in those exceptional places with rich (perhaps cal- 

 careous) soil which constitute considerably less than i% 

 of the whole area. On wooded bluffs along the muddy 

 rivers in bulloch, Montgomery, and wilcox, also near the 

 Rock House in dooly and in the woods where the Lafayette 

 formation seems to be absent (see p. no) in berrien. 

 Farther south seen in Effingham, Charlton, Brooks, and 

 Thomas Counties. More common in the upper third 

 of the coastal plain, and in Middle and Northwest Georgia, 

 where it flowers in March. 

 Widely distributed in the Eastern United States between 

 New England and latitude 30 . 



MIMOSAE^E. 



MORONGIA Britton, Mem. Torrey Club 5 : 191. 1894. 

 M. uncinata (Willd.) Britton, 1. c. 



Dry pine-barrens and sand-hills; not common, bulloch, 



TATTNALL, MONTGOMERY, COFFEE, WILCOX, IRWIN, BERRIEN. 



Fl. May-June. (Perhaps includes M. angustata, which I 

 have never succeeded in distinguishing.) Also in Middle 

 Georgia, and coastward to Cumberland Island; sometimes 

 a weed. 

 Southeastern United States mostly. 



KRAMERIAEiE. 

 KRAMERIA Loefl., Iter Hisp. 195. 1758. 

 ? K. secundiflora DC, Prodr. 1:341. 1824. "Sand-spur." 

 Sand-hills, bulloch (971), emanuel, tattnall, Mont- 

 gomery, telfair, coffee, wilcox. Fl. June-July. In- 

 land to Laurens County and coastward to Bryan. (See 

 Bull. Torrey Club 30 '.336. 1903.) 

 Also in central and West Florida (but not reported from 

 Alabama). It may well be doubted whether our sand-hill 

 plant is identical with the type of this species, which came 

 from Mexico. The absence of the genus from Alabama 

 (as far as known) is perhaps significant. Its range suggests 

 that of Froelichia Floridana (which see).
