160 ECONOMIC BOTANY OF ALABAMA 



Polygonella Americana (F. & AI.) Small. (P. Mcisncriana, 

 Shuttl.) 



Taller than the preceding, but still almost herl~)-like. Blooms 

 in summer. In Georgia I have seen it only in sand, hut Dr. Mohr 

 reports it as having been foimd on limestone hills in P)lount County 

 1)V one of his nieces. It is evidently rare in Alabama, and I have 

 not met it in this state at all. 



IB (?) "Limestone hills," Warnock Mountain, Pjlount County (Mohr). 



2A. Near Pisgah, Jackson County (Mohr). In sand along Bryant's 

 Creek (Harbison). These two records may possibly refer to the same 

 locality, or nearly so. 



(There are a few other plants which seem to grow equally well in sand 

 and on limestone, and possibly the absence of earthworms is the essential 

 factor for them.)
