12.— PENTSTEMON STATICIFOLIUM, Lindl. THE STATICE-LEAVED PENTSTEMON. 
-Engrsving. — Bot. Reg., t. 1770. 
Specific 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. 
13.— PENTSTEMON TRIPHYLLUM, THE THREE-LEAVED PENTSTEMON. 
Engravings. — Bot. Reg., t. 1245 ; aud omfiff. 2, in PI. 85. 
Specific Character. — Humble ; leaves three-four in a whorl, 
glabrous, bluntly cut ; lower ones oblong ; floral ones entire, linear- 
lanceolate, usually alternate ; peduncles two-tbree flowered, and are. 
Description, &c. — The elegance of the habit of growth of this plant forms an agreeable contrast to that of 
as well as the calyxes, clothed with cobwebbed down ; segments of 
corolla oblong, obtuse ; those of the lower lip equal ; sterile filament 
bearded. (G. Don.) 
I most of the other kinds of Pentstemon. The stem is slender, and very much branched, and the flowers are 
|S I produced in small panicles at the tips of the branches. It is a native of California, whence it was introduced 
' . in 1827.

I Description, &c. — The flowers are small and tubular, varying from blue to purple. The stem is erect, and

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. 
16— PENTSTEMON L^VIGATUM, Michx. THE SMOOTH PENTSTEMON. 
Synonymes. — Chelone laevigata, Pers. ; Chelone Pentstemon, I Specific Character. — Leaves smooth, nearly entire ; sterile 
var. Mill. filament bearded in the upper part ; shorter than the corolla. 
Engravings. — Bot. Mag., t. 1425 ; and our fig. 3, in PI. 86. 1 
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. laevigatum 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
