ROSACEAE 199 



Rosa setigera, ^Ix. 



A distinct species, with only three leaflets. 



Grows mostly in calcareous soils. Reported by Dr. ]^Iohr 

 from Falkville, Lookout ^Mountain (locality not specified), Hale 

 County (presumably in the black belt), and Uniontown (Perry 

 Co.). I have seen it only on chalky roadsides in Tireene County, 

 but it is there associated with several undoubtedly native s])ecies, 

 and it probably occurs, or did occur, in some natural habitat 

 near by. 



Rosa palustris, !Marsh. (Formerly referred to R. Carolina. L.) 



Differs from most other wild roses in growing in wet places. 

 Known in Alabama only from a swamp west of Triana, ]^Iad- 

 ison County (region IB), where I saw it on July "20, 1922. 



Rosa humilis, ^larsh. (R. Carolina. L.?) 



A low shrub, about knee-high, with large pink flowers, in 

 late spring. Grows in dry woods. \\'idely distributed, but no- 

 where common. (]\Iore than one species may be included.) 



IB. Madison and Morgan Counties. Limestone slopes of Warnock 

 Mountain, Blount Count\'. 

 IC. Lawrence Countv. 

 2A. Cullman County' (W. Wolf). 

 2B (?). Tuscaloosa County (E. A. Smith). 



3. St. Clair County (Mohr). 



4. Alpine Mountain, Talladega County (Mohr). Clay County. 

 6C (?). Hale Countv (Sereno Watson, according to Mohr). 



7 (?). Dallas County (Mohr). 

 low (?). Wilcox County (Buckley). 



Rosa laevigata, ]^Ix. (R. Siiiica. Ait.; R. Chcrokeciisis, Don.) 



Cherokee; Rose. 



A high-climbing vine-like shrub with evergreen leaves and 

 large pure white flowers in ]\Iarch and April. Supposed to be 

 native of China and Japan, but it was found in this country by 

 some of the earliest explorers, and may have been introduced in 

 some way before the time of Columbus. ( See ]\Iohr's Plant Life, 

 pp. 54, 544.) It is certainly not native in Alabama, anyway, for 

 it is strictly confined to unnatural habitats, especially roadsides. 

 It is occasionally cultivated for ornament, and has been recom- 

 mended for the "state flower" in this and one or two adjoining 

 states.
