Pentstemon (Greek for five stamens, all five stamens being present,
whereas related genera have only four; but in Pentstemon one of the
stamens is sterile). Sometimes written Pentstemon. Scrophu-
lariaceae. Pentstemon. Beard-tongue. Tubular- flowered bedding and
border plants, mostly of bright colors; many are natives in the
United States.

Perennial herbs or shrubs of medium or small size, spring- and
summer-blooming, glabrous or pubescent, the sts. mostly little
branched: lvs. opposite or whorled,entire or toothed (the upper ones
sometimes alternate): fls. in terminal racemes or thyrsoid clusters,
mostly showy, blue, red, purple, white; calyx 5-parted, with
imbricated segms.: corolla tubular, usually dilated at the throat,
distinctly or obscurely 2-lipped, the upper lip 2-lobed or notched
and the lower 3-lobed; fertile stamens 4, didynamous the fifth
sterile and sometimes bearded, all of them included or not exserted;
style filiform and stigma capitate: fr. an ovoid, globose or oblong
dehiscent caps., with numerous seeds. Pentstemon is a typical
American genus. One species is native to N. E. Asia and many to the
cooler parts of Mex., but the larger number of the species inhabit
the U. S. and Canada, particularly the western parts. Krautter admits
148 species in his monograph in 1908 (Contr. Bot. Lab., Univ. of Pa.
III). They are all herbs, although some species are somewhat woody at
the base. It is difficult so to arrange the species of Pentstemon as
to make them easy of determination by the horticulturist. Gray's
account in the Synoptical Flora (Vol. 2, Part 1) describes the
American species north of Mex.; and this account has been followed
here in the main. The arrangement of species, however, has been
modified considerably to admit the Mexican species and to make the
group easier for the beginner. Later writers are inclined to raise
the Grayan varieties to the rank of species.

For the hardy border, pentstemons are most satisfactory plants, and
the great number of showy species allows much latitude in choice of
color and habit. All are perennial, but some of them bloom the first
year from seed. In a dry and hot place they are likely to be
short-lived, although nearly all the species thrive best in full
exposure to sun. They should have good deep garden soil. They are
propagated by division and by seed, the latter usually being
preferred. Many of the species are not hardy in the northern states,
but P. barbatus and its varieties, P. hirsutus, P. laevigatus and
variety, P. confertus and variety, P. diffusus, P. ovatus, P.
grandiflorus, P. acuminatus, P. angustifolius, P. glaber and
varieties, and also others, may be expected to stand in the North,
particularly if given a protection of leaves. An excellent garden
race has been produced, here designated as P. gloxinioides. This
seems to be a product of hybridization and selection. It is little
known in American gardens, although it is a handsome and deserving
plant. Some of the forms of it are treated as annuals. Most of the
species described in this account are not domesticated or modified
plants, but are sold or distributed as stock secured more or less
directly from the wild.

base, 2 ft.: lvs. oblong, sharp-toothed, sessile: fls. deep carmine-
red, on 1-3-fld. peduncles; corolla 1 in. long, broadly tubular, with
short 2-lipped limb; sterile filament naked. Texas. J.F. 3:227.—P.
pygmaeus is a name listed abroad: "very compact-growing; pale purple
and white fls."—P. virgatus, Gray. Glabrous or slightly glandular,
the st. strict and long: lvs. linear-lanceolate: fls. lilac with
purple veins, in a virgatc thyrse; corolla 3/4 in. long, with a wide
throat and distinctly 2-lipped. New Mex., Ariz.
