THE LADIES' FLOWER-GARDEN 
8.— PENTSTEMON PRUINOSUM, Dough THE BLOOM-LEAVED PENTSTEMON. 
Engritings. — Bot. Reg., t. 1280 ; a.aioar Jig. 4, PI. 79. 
Specific CuiBiCTEa. — Leaves grey, radical ones petiolato, entire, 
or toothed ; cauline leaves toothed, sessile ; superior bracteas entire ; 
flowers verticillate ; calyxes and bracteas villous ; corolla glabrou8| 
twice as long as the calyx ; segments of the limb roundish, entire. 
(G. Don.) 
Description, &c. — The flowers of this species are disposed in whorls like those of the two preceding kinds ; 
but they are so much larger, that they make a much better appearance. They are of a very beautiful blue, with 
a white throat, and the leaves are perfectly glaucous. The species was found by Douglas, on the banks of the 
Columbia, whence it was introduced in 1827. It is quite hardy, and a true perennial ; but according to Dr. 
Lindley, it is apt to exhaust itself so much by over-flowering, as frequently to die the second year. To prevent 
this, he advises the cultivator to pinch off part of the flower-buds. 
§ 3. — Corolla bilabiate. Upper lip of corolla compressed ; the lower plaited. 
9 PENTSTEMON ATTENUATUM, Dougl. THE ATTENUATED-LEAVED PENTSTEMON. 
ENGRiviNG.— Bot. Reg., t. 1295. 
Specific Character. — Stem erect, pilose at top ; radical leaves 
elliptic, acute, petiolale ; superior ones ovate-oblong, stem-clasping. 
sessile, all quite glabrous and quite entire ; panicle strict, and are, as 
well as the calyxes and corollas, downy j capsule glabrous ; sterile 
filament bearded. (G. Don.) 
Description, & c. — This is a very handsome species and quite hardy. The stem is from one to two feet 
high ; it grows freely in any common garden soil, and it is propagated by division of the roots. The leaves are 
large and handsome, and of a very deep green ; and the flowers, which are of a pale yellow, are disposed in 
a close panicle, and not in whorls. They are produced from July to the end of September. The species is a 
native of the mountains of California, whence it was sent home in 1827. 
10.— PENTSTEMON DEUSTUM, Dougl. THE BURNED PENTSTEMON. 
Engraving. — Bot. Reg., t, 1318. 
Specific Character. — Stem almost simple, ascending, glabrous ; 
leaves deeply toothed ; radical ones ovate-oblong ; those near them 
spathulate ; cauline leaves oblong, acute, sessile ; upper ones almost 
quite entire ; calyxes glabrous ; limb of the corolla flat, with retuse 
segments ; upper ones the smallest. (G. Don.) 
Description, &c. — This species bears considerable resemblance to the last, both in its habit of growth, and 
in the colour of its flowers, but it differs in its coarsely-jagged leaves. It is a native of North West America, 
where it was found by Douglas, on open, rocky plains, exposed to the burning sun, and hence its somewhat 
singular name. It is quite hardy, and is readily increased by division. It was introduced in 1829. 
11.— PENTSTEMON DIFFUSUM, Oougl. THE DIFFUSE PENTSTEMON. 
forming a terminal panicle ; calyx turbinate, with jagged segments ; 
sterile filament of about the same length as the tube, bearded. 
Ekoravino. — Bot. Reg., t. 1132. 
Specific Character. — Stem branched ; leaves ovate-oblong, gla- 
brous, unequally serrated; peduncles axillary, many-flowered, the whole | 
Description, &c. — This is a very handsome species, with evergreen leaves, and decumbent rooting-stems, 
by which it is readily increased. It is a native of the open ground and banks of rivers in North "West America, 
where it was found in great abundance by Douglas, by whom it was introduced in 1827. It grows freely in 
any light soil, and produces abundance of flowers from June to October.
