THE LADIES’ FLOWER-GARDEN 
mulching of dead leaves, or the bark from an old pine pit, during the winter. Both this species and P. Murray- 
anus may be propagated either by seeds or by cuttings. P. argutus was introduced about 1836. 
Section II. — Anthers ciliated or downy. 
24.— PENTSTEMON GLABRUM, Pursh. THE GLABROUS PENTSTEMON. 
Synonvmk. — P. erianthera, Nutt. 
Engraving. — Bot. Mag., t. 1672. 
Specific Character. — Very smooth ; leaves sessile, ovate-lanceo- 
late, entire, having the margins partly undulated ; peduncles many- 
flowered, secund ; segments of calyx roundish-oval, acuminated ; 
corolla sub-campanulate ; sterile filament slightly bearded under the 
retuse apex ; anthers pubescent. (G. Don.) 
Description, &c. — This is a very singular-looking plant, with the flowers crowded together in the same 
manner as in Chelone. The flowers are very large, and of a deep purple. The species is quite hardy, and it is 
a native of Louisiana, in North America, whence it was introduced in 1811. It grows about a foot or a foot 
and a half high, and flowers in June and July. 
25.— PENTSTEMON GLANDULOSUM, Dougl. THE GLANDULAR PENTSTEMON. 
Engraving. — Bot. Reg., t. 1262. j acute, almost quite entire; peduncles many-flowered; calyx loose, 
Specific Character. — Plant clothed with a glandular pubescence ; | with ovate segments ; corolla ventricose ; anthers ciliated ; sterile 
radical leaves ovate, coarsely toothed; cauliue ones stem -clasping, 1 filament glabrous. (G. Don.) 
Description, &c. — This species is a native of North America, where it was found by Douglas on the banks 
of a river in the Rocky Mountains, 6,300 feet above the level of the sea. It was introduced in 1827, and is 
quite hardy in British gardens ; where it may be propagated either by its seeds or by division of its roots. 
26.— PENTSTEMON VENUSTUM, Dougl. THE GRACEFUL PENTSTEMON. 
Engraving. — Bot. Reg., t, 1309. i many-flowered, the whole forming a panicle ; calyx glabrous ; corolla 
Specific Character. — Stem suffruticose, erect, glabrous ; leaves ventricose, ciliated ; anthers pilose ; sterile filament bearded at top. 
sessile, ovate-lanceolate, acuminated, denticulated, glabrous ; peduncles | (G. Don.) 
Description, &c. — This is a very handsome species, with flowers as large as those of the Foxglove, but 
disposed in a most graceful panicle. It may be propagated either by seeds or by cuttings ; but the latter is the 
best mode, as the plants vary a good deal from seed. It is a native of North-West America, where Douglas 
found it in the dry channels of rivers, among the mountains. It was introduced in 1827- 
27.— PENTSTEMON RICHARDSONII, Dougl. DR. RICHARDSON’S PENTSTEMON. 
Engravings. — Bot. Reg., t. 1121 ; Bot. Mag., t. 3391. . with ovate-acute segments ; corolla ventricose ; anthers ciliated ; sterile 
Specific Character. — Herbaceous; leaves sessile, pinnatifid; filament bearded, with a few hairs at the apex. {G. Don.) 
peduncles few-flowered ; calyx clothed with glandular pubescence, | 
Description, &c. — This was one of the earliest species found by Douglas, and it was named by him 
in compliment to Dr. Richardson, the celebrated companion of Captain Franklin, in the overland expedition 
undertaken to discover the North-West passage. It is quite hardy in British gardens, and was introduced 
in 1825.
