Description, &c. — The stem of this species grows about a foot high. The leaves are large, strongly 
veined, and wrinkled. The flowers are numerous, and of a dark crimson. They are globular, and contracted at 
the mouth like those of some kinds of heath. The species is a native of Bohemia ; but the year of its introduction 
is not known. It flowers in May, and is increased by dividing the roots. 
OTHER SPECIES OF SYMPHYTUM BELONGING TO § 1. 
S. BULBOSUM, Schmidt. 
A native of the Apennines, with bulbous roots and yellow flowers. Introduced in 1829, and flowering 
from June till August. 
S. CORDATUM, Waist, et Kit. 
A native of Hungary, with tuberous, creeping roots, large hairy leaves, and cream-coloured flowers. It was 
introduced in 1813, and it flowers from May till July. This is the S. pannonicum of Persoon.

Specific Character Leaves lanceolate-ovate, undulated, decur- I 
Description, &c. — This is a very pretty species of Comfrey, from the flowers being white, and rather 
larger than those of the ordinary kinds. It begins to flower early in spring, and continues producing fresh 
blossoms nearly all the summer. It is not, however, a suitable plant for a small garden, as it grows about two 
feet high, and the leaves are large and somewhat coarse. It is a native of Turkey, where it grows on the 
banks of rivers; and it was introduced in 1752. 
3.— SYMPHYTUM CAUCASICUM, Marsch. THE CAUCASIAN COMFREY. 
Engravings. — Bot. Mag., t. 3188 ; and our fig. 4, in PI. 77. j part glutinous; leaves ovate-lanceolate, attenuated at the base, semi- 
Specific Character. — Stem branched, lower part hairy, upper | decunent, hairy ; calyx obtuse. 
Description, &c. — This plant grows about two feet high, and the stem, though hairy near the base, becomes 
smooth and covered with a glutinous substance on the upper part. The flowers are produced in long terminal 
racemes, each stem producing two racemes. The flowers are very pretty, being at first of a delicate pink, and 
afterwards becoming a beautiful azure-blue. The species is a native of the country around Mount Caucasus, 
whence it was introduced in 1830. It is, perhaps, the most ornamental species of the genus, on account of the 
smoothness and small size of the leaves, and the great abundance and brilliant colours of the flowers. It is quite 
hardy in British gardens.
