Dry sandy soil, fields, scrub oak and pine land, through the Coastal 

 Plain from North Carolina to central Florida and eastern Texas, 

 mostly common; inland to the granite of central Georgia, and in 

 upper South Carolina. Usually with broader leaves inland, while 

 in the pine-barrens of the Coastal Plain the cauline may be fewer 

 and usually much smaller so that the stem appears somewhat scapose. 



Flowering in April and May, fruiting in June and July. Corolla 

 externally reddish-purple, paler on anterior side; within red-purple 

 on posterior lobes with on each a fine median line of deeper color, 

 anterior lobes white, with deep red-purple streaks, three to each 

 lateral lobe, and five, which anastomoze distally, to the median 

 lobe. Sterile filament with yellow hairs. 



This and other southern species have been freely listed as "Pen- 

 stemon puhescens" or "P. hirsutus," a northern plant,, with lavender 

 corollas, and not definitely known from our area.
