D1DYNAM1A ANGIOSPERM1A. 
dissectis, laciniis line- 
aribus plerumque ob- 
tusis ; floribus panicu- 
latis. E. 
dissected, the seg- 
ments linear and gen- 
erally obtuse ; flowers 
in panicles. 
Stem about 2 feet high, slightly pubescent. Leaves glabrous, divided 
to the base, compoundly dissected or pinnatifid, the segments irregular in 
length, not pectinate, all linear, and generally obtuse. Flowers in a pan- 
icle composed of opposite branches, bearing a few flowers near and at the 
summit of the stem. Corolla purple, segments of the upper lip longer 
than those of the lower and more obtuse. Stamens shorter than the co- 
rolla, sterile filament as long or longer. Style nearly as long as the sta- 
mens. Stigma simple. 
This remarkable species was sent me as a Pentstemon from Louisville, 
Georgia, by Mr. Jackson, its leaves have some affinity to the Seymeria, 
but the structure of the panicle and of the flower as far as the specimen 
permitted me to examine it, is exactly similar to the other species of this 
genus.
