leaves sessile, cordate-ovate, toothed, pubescent ; cymes nearly sessile, 
tomentose ; corolla ventricose, pubescent. (G. Don.) 
Enghjving.— Bot. Reg., t. 1770. 
SpEcinc Character. — Stems ascending, pubescent ; radical leaves 
oblong-lanceolate, narrowed to the base, entire, glabrous ; cauline 
Description, &c. — The flowers are large, and very handsome ; but the plant, in its habit of growth, is very 
nearly allied to P. diffusum. It grows best in a peat border. It is a native of California, and was introduced 
in 1834. The root-leaves are sometimes seven inches long. 
as well as the caly-ies, clothed with cobwebbed down j segments of 
corolla oblong, obtuse; those of the lower lip equal ; sterile filament 
bearded. (G. Don.) 
13.— PENTSTEMON TRIPHYLLUM, Dougl. THE THREE-LEAVED PENTSTEMON. 
Engravings.— Bot. Reg., t. 1245 ; and omjig. 2, in PI. 79. 
Specific Character. — Humble ; leaves three-four in a whorl, 
glabrous, bluntly cut ; lower ones oblong; floral ones entire, linear- 
lanceolate, usually alternate ; peduncles two-three flowered, and are, 
Deschiption, &c. — The elegance of the habit of growth of this plant forms an agreeable contrast to that of 
most of the other kinds of Pentstemon. The stem is slender, and very much branched, and the flowers are 
produced in small panicles at the tips of the branches. It is a native of California, whence it was introduced 
in 1827. 
14.— PENTSTEMON GRACILIS, Nutt. THE SLENDER PENTSTEMON. 
few-flowered ; sterile filament bearded longitudinally ; corolla smooth 
inside ; segments of the calyx linear, oblong. 
Engravings Bot. Mag., t. 2945 ; and our/^;. 2, in PI. 80. 
Specific Character. — Stem smooth and slender ; leaves smooth, 
linear, acute, half stem- clasping, sharply serrulated ; panicles simple, 
Description, &c. — The flowers are small and tubular, varying from blue to purple. The stem is erect, and 
the leaves sharply serrulated. The plant was discovered first by Mr. Nuttall, in the Mandan territory ; but it 
has since been found by several collectors in different parts of North America. It was introduced in 1824. 
15.— PENTSTEMON PUBESCENS, Ait. THE DOWNY PENTSTEMON. 
Synonymes. — Chclone Pentstemon, Lin. ; Asarina erecta. Mill. 
Engraving. — Bot. Mag., t. 1424. 
Specific Character. — Stem pubescent ; leaves repandly serru- 
lated, lanceolate-oblong, sessile, stem-clasping ; flowers in panicles ; 
the sterile filament bearded from the summit below the middle. ( G. 
Don.) 
Description, &c. — This is a very pretty plant, with rather broad leaves and abundance of flowers, slightly 
tinted with pink. It is a native of the Alleghany Mountains, in North America, whence it was introduced 
before 1738 ; and hence it was one of the first species of Pentstemon introduced into our gardens. It very 
frequently dies the second year, having exhausted itself by over-flowering. 
Specific Character. — Leaves smooth, nearly entire ; sterile 
filament bearded in the upper part ; shorter than the corolla. 
16.— PENTSTEMON L^VIGATUS, Michx. THE SMOOTH PENTSTEMON. 
Synonymes. — Chelone Isevigata, Pers. ; Chelone Pentstemon, 
var. Mill. 
Engravings. — Bot. Mag., t. 1425 ; and om fig. 3, in PI. 80. 
Description, &c. — ^The principal difference between this and the preceding species consists in P. pubescens 
having its leaves covered with a soft down ; whilst in P. Isevigatus these parts are perfectly smooth. The 
present species is also found in the more southern parts of North America, and it is rather more tender than
