GENUS I. 
CONVOLVULUS, Lin. THE BIND-WEED. 
Lin. Syst. PENTANDRIA MONOGYNIA. 
Gekkkic Character. — Calyx of five sepals. Corolla campanulato. Style one ; stigmas two, linear-cylindrical, often revolute. Ovarium two- 
celled, four-ovulate. Capsule two-celled. (G. Don). 
Description, &c. — The plants commonly called Convolvulus were divided into the two genera. Con- 
volvulus and Ipomoea, by Linnasus, principally on account of the shape of the lobes of the stigma, which in 
Convolvulus are slender and quite distinct, while in Ipomoea they form a globose head. Modern botanists have 
made several other genera out of the old genus Convolvulus, the principal of which, are : — Calystegia, from two 
Greek words, signifying a covered calyx, in allusion to two large bracts which inclose the flower ; and Pharbitis, 
which is said to signify, highly-coloured, and which is distinguished by the capsule having three or four cells 
instead of two. The first of these genera includes the common bind-weed of the hedges, and the allied species ; 
and the second, the major Convolvulus and other species with brilliantly-coloured flowers. All the species 
described in the present work will be given under their Linntean names of Convolvulus and Ipomoea.

Synonyme. — Convolvulus japonicus, Banks. I striated. Leaves secund, fleshy, hastate. Peduncles solitary, fleshy.

Specific Character. — Stem twisted, nearly simple, angularly | 
Description &c.' — This is a very pretty little plant, with purplish crimson flowers, marked with a pale 
yellow star. The root is creeping, and spreads rapidly. The leaves are fleshy, halbert-shaped, and of a greyish 
green. The plant ia well deserving of cultivation ; the only objection to it being the short duration of its flowers, 
which open early in the morning and often fade before the middle of the day. It is a native of China, whence 
it was introduced in 1816. 
2._CONVOLVULUS SCAMMONIA, Lin. THE COMMON SCAMMONY. 
SvNONYMEs. C. Syriacus, Tourn. ; Scammonia Syriaca, Bauh. [ Specific Character. — Leaves sagittate or truncate. Peduncles 
Engraving. Sweet's Brit. Flow. Card., 2d series, t. 173. | cylindrical, three-flowered; bracts lanceolate, remote from the calyx. 
Description, &c. — This species is remarkable for its long, fusiform root, which abounds in an acrid, milky 
juice, and is used in medicine. The stems are numerous, and generally grow from ten to fifteen feet high, twining 
themselves round any object they can meet with, that will afibrd them support. The flowers are large and white, 
greatly resembling those of the common bind-weed of the hedges, but produced in much greater abundance. The 
species is perfectly hardy, and continues to flower till late in the autumn. It is generally increased by seeds, 
which it ripens freely. It is a native of the Lev*it, and was introduced before 1596. 
3.— CONVOLVULUS BRyONI.S;FOLIUS, Sims. THE BRYONY-LEAVED CONVOLVULUS 
Engratings. — Bot. Mag., t. 943 ; and our fig. 3, in PI. 74. 
Specific Character. — Leaves seven-lobcd, palmate, hispid ; middle lobes sinuated. Peduncles axillary, very long, articulated. Flowers solitary 
Description, &c. — This very beautiful little plant is of a dark rose colour. Tlie leaves are hairy on both 
sides ; and though they vary considerably in shape, they are generally divided into seven unequal lobes, of which 
the central one is much the largest. The petioles are generally as long as the leaves, and channelled on the upper
