C. UNDULATUS, Cav. ; syn. C. EVOLVULOIDES, De^. 
This species, whidi is generally called the African Convolvulus, has large flowers, resembling those of 
C. tricolor, except in the rim or limb, as botanists call it, which is pink instead of blue ; but there is a variety 
■which is blue and white. It is a prostrate plant, and a free flowerer. It was introduced in 1810. 
C PERUVIANUS, Spreng.; syn. IPOMffiA CUSPIDATA, Ruiz et Pavon ; PHARBITIS CUSPIDATA, G. Don. 
The Peruvian Convolvulus has large purple flowers. It is a native of Peru, in stony places, and was 
introduced in 1732.

Description, &c. — The diflFerence between the genera Ipomoea and Convolvulus is very slight, consistins; 
principally in the shape of the lobes of the stigma, which in Ipomoea form a globose head, while in Convolvulus 
they are slender and thread-like. The division of the genera was made by Linnaus, and it has been followed 
by all subsequent botanists. Ipomoea signifies, to strike the sight, — in allusion to the beauty of the flowers.

Varieties. — I. c. 2 pubcscens, Cham, et Schlecht. This variety 
has the leaves covered with a soft dense down, and never three-lobed. 
Description, &c. — This species is a twining plant, with heart-shaped leaves, and bright scarlet flowers. It 
is a native of Carolina, and the West India Islands, whence it was introduced in 1759, being first cultivated by 
Miller, when he was curator of the Botanic Garden, at Chelsea. Since then it has been generally grown in 
nurseries, though but seldom in private flower-gardens ; partly, no doubt, from its being confounded with some 
of the tender kinds, which it strongly resembles. The scarlet Ipomoea is, however, quite hardy, and only 
requires sowing in the open ground like other annuals. Three seeds are usually sown about four inches asunder 
in the form of a triangle ; and when the young plants are about six or eight inches high, a stick is put in the 
centre for them to twine round. A slight iron frame with an umbrella-top, or any other frame in wire or lattice- 
work, may be adopted, or a piece of packthread stretched out for them, or the young plants may be trained 
against a wall or paling. They do best, however, without tying or nailing, and when suffered to twist them- 
selves round anything that may be near them. We saw some in the autumn of 1838 in the Lewisham nursery, 
which had twisted themselves round some young apple trees, and which hung down in graceful festoons from the 
branches. Seeds of this species may be had at Carter's and other seed-shops ; and if sown in March or April 
the plants will flower in July or August. If wanted to flower early, the plants may be raised on a hotbed, and 
transplanted in March or April, when they will flower in May or June. They are said to succeed best in a very 
rich soil and in a warm sheltered situation ; but in these situations the flowers, though lao-ger, are generally of a
