-H- No runners or prostrate sterile shoots. 



P. Floridana, Benth. Stems erect and strict, a foot or two high, slightly hairy or nearly 

 glabrous below, as are the lanceolate-linear or broadly linear rather rigid leaves, the

 setaceous : lobes of the light purple corolla roundish-obovate, entire. Prodr. 1. c. 304 ; 

 Chapm. Fl. 309. Dry open woods, Florida, Chapman, JRiif/d. Foliage, &c., nearly as in

 sessile base to the acute point : corymb at length loose : teeth of the hairy more or less 

 viscous calyx subulate-setaceous or awn-like : lobes of the (pink, purple, rose, or sometimes
