HYPERICACEAE 273 



Hypericum nudiflorum, Mx. (H. cistifohitiii. Lam.?) 



A slender sparingly branched shrub, with leaves about the 

 size of those of H. aiircuiii. Grows mostly on edges of sandy 

 swamps ; rather rare. 



13. Swamp of Three-mile Creek, Mobile County (Mohr). 

 Hypericum opacum, T. & G. 



Another small weak comparatively unbranched shrub, smaller 

 in every way than H. nudifloniiii, and differing from H. sphaero- 

 carpuin in having fewer and larger leaves. Blooms in summer. 



Grows in sandy bogs and low pine lands, in the southwestern 

 pine hills (region 13). Dr. Mohr reported it from Mobile and 

 Baldwin Counties, and I have seen it in Escambia and Covington. 



Hypericum sphaerocarpum, Mx. 



A small erect shruJj with a single stem, woody at the base, 

 herbaceous and branched above. Blooms in May and June. 

 Grows on limestone outcrops. 



IB. Madison and Franklin Counties (Mohr). (These records may 

 pertain to the next species, which was described after Dr. Mohr's death.) 



7. Between Eutaw and Boligee, Greene County. Bald prairies near 

 Gallion, Hale County (Mohr). 



11. Limestone glade near Suggsville, Clarke County. 



Hypericum turgidum, Small. (Fl. S. E. U. S., 788. 1903) 



Similar to the preceding, and perhaps not specifically distinct. 



Grows on f lattish outcrops of limestone, in the Tennessee Val- 

 ley (region IB). Collected by Ferdinand Rugel in 1843, some- 

 w^here between Huntsville and "Summerville" (doubtless meaning 

 Somerville), and later by W. M. Canby near Huntsville. Found 

 by the writer in September, 1927, at two places in Morgan County, 

 several miles apart (both perhaps near Rugel's route), and in May, 

 1928, near the base of Warnock Mountain in Blount County.
