Pentstemon, which is compounded of two Greek 
words, pente, five, and stem A, a stamen; is used 
to distinguish a genus which has been separated 
from Chelone ; because, in addition to the four un- 
equal semens of Chelone, which characterize the 
class didynamia, it possesses an imperfect fifth sta- 
men. Digitalis, the systematic name of the Fox- 
glove, is given as a secondary title, from the resem- 
blance of their flowers. 
Some difference of opinion has prevailed respect- 
ing the propriety of dividing the genus Chelone ; and 
it must be acknowledged there appears no real ne- 
cessity for doing so. 
This handsome upright growing plant, from Ar- 
kansa, in North America, is a desirable addition to 
a collection of herbaceous beauties. It is unob- 
trusive considering its height; and if some of its 
stems be cut down before it has done flowering, 
a second crop will, generally, be produced. 
It may be increased by division of its roots ; and 
if this be insufficient, cuttings may be taken of its 
stems, about midsummer, which will strike root un- 
der a hand-glass.
