4 .— PENTSTEMON DIGITALIS, Nutt. THE FOXGLOVE-LIKE PENTSTEMON. 
Synonyme. — Chelone digitalis, Swt. 
Engraving.— Swt. Brit. Flow. Gard., t. 120; and our fig. 1, in 
PI. 88. 
Specific Character. — Stem erect, sub-pubescent. Leaves smooth 
and glossy, slightly toothed with very small gland-like teeth, and 
covered with numerous small dots ; lower leaves oblong-lanceolate, 
attenuated at the base and running down the petiole, strongly nerved 
beneath, and channelled on the upper side ; stem-leaves cordate, ovate, 
acuminate, sessile. Flowers in racemose panicles ; corollas clothed 
with glandular hairs, slightly bearded in the throat ; sterile stamen 
longer than the others, and bearded half way down with long white 
hairs. 
Description, &c. — This species was found by Nuttall in the Arkansa territory of North America, and sent 
to England in 1824. It is quite hardy in British gardens, and will grow in any common garden soil. It is 
most readily propagated by cuttings,which will soon strike root if planted under hand-glasses. The flowers are 
white, with a very slight tinge of pink, and they appear from June to September. The plant grows from one 
to two feet high.

5.— PENTSTEMON OVATUM, Dougl. THE OVAL-LEAVED PENTSTEMON. 
Engravings. — Bot. Mag., t. 2903 ; Swt. Brit. Flow. Gard., 2nd I serrated ; root leaves petiolate, upper ones stem-clasping. Flowers in 
ser., t. 211. a racemose panicle ; segments of the calyx lanceolate ; corolla gland- 
Specific Character. — Pubescent. Leaves ovate-cordate, den lately | ular. 
Description, &c. — This is a very beautiful specie.s, as, though the flowers are small, they are extremely 
numerous, and of a most brilliant and beautiful blue. They are also disposed in a number of small cymes so as 
to form a large and very handsome panicle. The species is a hardy perennial, a native of the limestone rocks 
among the mountains near the Great Rapids of the Columbia River ; and it was introduced by Douglas', in 182(1. 
It grows best in calcareous soil, particularly in chalk, or chalk mixed with loam ; and it is increased either by 
seeds which it ripens freely, or by cuttings. It varies very much as regards the colour of the flowers. 
6.— PENTSTEMON PROCERUM, Dougl. THE TALL PENTSTEMON. 
Engraving — Bot. Mag., t. 2954. I nate. Flowers in a verticillate spike ; segments of the calyx mem bra- 
Specific Character. — Stem erect, straight, nearly simple. Leaves naceous, mucronate ; sterile filaments toothless at the base. ( G. 
lanceolate, entire ; lower ones petiolate, upper ones sessile, subcon- 1 Don.) 
Description, &c. — This species is more singular than beautiful. The flowers, which are purple and very 
small, are disposed in small whorls round the stem, which is quite straight and erect, and from one to two feet 
high, the whole being at a considerable distance from each other. The species is a native of California, where it 
was found in swamps and overflowed meadows near the Grand Rapids, on the river Columbia. It was intro- 
duced in 1827, and it blossoms in June. It ripens seeds freely. 
7.— PENTSTEMON CONFERTUM, Dougl. THE CROWDED-FLOWERED PENTSTEMON. 
Engraving. — Bot. Reg., t. 1260. 
Specific Character. — Leaves quite entire, glabrous ; radical ones 
spathulate, acuminated, on long petioles ; superior one sessile, ovate, 
acuminated ; peduncles axillary, short, bearing each a cyme of crowded 
flowers, which appear verticillate ; upper floral leaves reduced to jagged 
or serrated bractcas ; calycine segments acute, mucronate, jagged or 
serrated ; corolla a little longer than the calyx ; sterile filament 
bearded. (G. Don.) 
Description, &c. — The flowers are yellowish, and very small, being disposed in distant whorls, like those 
of the preceding species. It is by no means handsome, but it has the advantage of being quite hardy, and ripen- 
ing its seed freely. It is a native of California, whence it was introduced in 1827.
