Dry aie soil, fields, scrub oak and pine land, Deca 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 pubescens” or “P. hirsutus,’”’ a northern plant, with lavender 
corollas, and not definitely known from our area.
