side. The peduncles of the flowers are also very long, and spring from the axils of the leaves, being jointed or 
articulated with the stem. It is a native of China, whence it was introduced in 1802. It is quite hardy in the 
open border, flowering from June till August, and perfecting its seeds in the autumn.

SyN0NKME8. — C. argenteua, Bauh.; C. Althaefolius, Clus,; Pa- Specific Characteiu — Lower leaves cordate, einuuted, silkjr ; upper 
paver corDutum, Ger. ; Silky-leaved Convolvulus, ones deeply cut ; lobes linear, spreading. 
Engiuvino. — Bot. Mag., t. 359. 
Description, &c. — This is a most elegant plant, remarkable for the silvery whiteness of its leaves, and its 
beautiful rose-coloured flowers. It is a native of the south of Europe, being found in great abundance on the 
mountains of Naples, and of Spain and Portugal. It was introduced in 1656. It flowers in June and July, and 
is increased by dividing its stoloniferous roots, as it seldom ripens its seed in this country. It requires a slight 
protection during very severe winters. 
Specific CHiRicxEa. — Leaves sagittate ; peduncles quadrangular ; 
one-flowered ; bracts cordate, shrouding tiie calyx. 
5.— CONVOLVULUS AMERICANUS. THE AMERICAN CONVOLVULUS. 
Synonymes. — C. sepium, var. Americanus, Sims ; Calystegia in- 
flata, Desf. ; the American Bear-bind. 
Engravings. — Bot. Mag., t. 732 ; and our fig. 1, in PI. 74. 
Description, &c. — This very beautiful plant is nearly allied to the common great bind-weed, or large white 
convolvulus of the hedges. It is, however, much handsomer,, the leaves being larger, and the flowers of a deep 
rose-colour. It is a native of North America, whence it was introduced about 1750 ; and it is quite hardy in 
British gardens, flowering abundantly, and retaining its flowers much longer than the common wild plant, which 
it so nearly resembles. The near approach of the bracts to the calyx, mark it as of the modern genus, Calystegia, 
which is distinguished by this peculiarity. This species of Convolvulus produces a very good eiFect, when 
trained to trellis-work ; and there is a very striking instance of this in the garden of the Dowager Duchess of 
Bedford, at Camden Hill. 
6.— CONVOLVULUS RENIFORMIS, Spreng. THE KIDNEY-LEAVED CONVOLVULUS. 
Specific Character. — Stem angularly branched, elongated, pros- 
trate ; leaves kidney-shaped, fleshy ; peduncles round ; bracts cor- 
date, cmarginate, close to the calyx. Root succulent, creeping. 
Description, &c. — This is a pretty little species, very desirable for rock work or covering a bank, as its 
stems and branches lie flat on the ground, and are not only very numerous, but extend to a great length. The 
species is a native of New Holland, whence it was introduced in 1822. It is easily propagated by dividing the 
roots ; but it requires protection when the winter happens to be severe.

Description, &c. — A pretty little plant, with pink flowers and cordate leaves. A native of Siberia, whence 
it was introduced in 1820. It is quite hardv in British gardens, and it is propagated either by seeds, or by 
nerves of the under surface. Peduncles axillary, one-flowered, tomen- 
tose ; bracts ovate, close to the calyx. Segments of the calyx lance- 
olate, acute, outer two broader than the others. Style longer than 
the stamens.
