flowered. Leaves stem-clasping, acute. Calyx obsoletely tetragonal ; 
segments acuminate, with a membranaceous margin. Corolla four- 
cleft, segments obovate, flnely cut at the margins. 
SvNONYME. — Gentiana crinita, Frcel. 
Engravings. — Sweet’s Brit. Flow. Card. t. 139; and our fig. I, 
■in Plate 70, under the name of Gentiana crinita. 
Specific Character. — Stem erect, quadrangular ; branches one- 
Description, &c. — This species is a biennial, and quite distinct from the previous species, with which it is 
often confounded, which is a true perennial. The flowers of G. crinita are very curiously, and delicately cut at the 
margins, so as to give them a hairy appearance. The species is a native of North America, whence it was intro- 
duced in 1824. It should be grown in peat, and the seeds should be sown as soon as they are ripe. 
OTHER SPECIES OF GENTIANELLA. 
There are some other species of Gentianella, but they are rarely seen in British gardens, with the exception of 
G. ciliata, which is often confounded with G. barbata, to which it bears considerable resemblance. 
GENUS II. 
GENTIANA, Lin. THE GENTIAN. 
Lin. Sgst. PENTANDRIA MONOGYNIA. 
Generic Character Corolla campanulately funnel-shaped, four-flve cleft. Stigma two-lobed. Seeds oblong, or roundish. 
Description, &c. — The genus Gentiana of Linnmus has been divided by modern botanists into six or seven 
different genera ; but to avoid confusion I shall generally retain the old name, as being that by which the plants 
are best known, merely noticing the new name, so that my readers may be able to recognise the plants if they 
should be met with under their new designation. Tlie name of Gentian is said to be derived from Gentius, King 
of Illyria, who first tried the tonic properties of the roots. 
1.— GENTIANA MACROPHYLLA, Pall THE LONG-LEAVED GENTIAN. 
Engraving. — Bot. Mag. t. 1414. I crowded, sessile, verticillate. Leaves growing from the root and near the 
Specific Character. — Corolla five-cleft, rarely four-cleft. B'lowers | flower, leaving the stem bare between ; lanceolate, very long, curved. 
Description, &c. — This plant is more curious than beautiful ; but it is remarkable for its long narrow leaves, 
which curl round, and for the naked part of its stem, between the leaves, which has a very singular appearance. 
It is quite hardy, and is generally propagated by seeds. It is a native of Siberia, and was introduced in 1796. 
The flowers are rather small, and of a very dark blue.

mon Gentian-root. 
Engravings. — Wood Med. Bot. t. 156; Church, et Stev. Med. 
Bot. vol. iv. 
Specific Character. — Calyx spathe-like. Corolla with a short 
tube, and a five-cleft limb, furnished with a green gland at the base of 
each segment. Flowers verticillate, subcymose. Leaves broad, ovate. 
Description, &c. — The plant produces the Gentian-root used in medicine, and vulgarly called Bitters. These 
roots are long and thick ; brown on the outside and wrinkled, but of a yellow colour within, and of a spongy 
substance. The flowers are yellow and spotted, and so different in their construction from those of the true
