twining a little, but not like the other species so much so as to require support. On the contrary the slender 
thread-like stems of this curious little plant lie on the ground, and only wind round each other. This species is 
a native of Sicily, the coast of Barbary, aad Greece ; and it was introduced before 1640, according to Parkinson, 
by Mr. James Boel. It is quite hardy, and seeds may be had at Carter's. From the sniallness of its flowers, 
however, it is rarely cultivated in flower-gardens. 
4.— CONVOLVULUS ELONGATUS, mild. BROUSSONET'S TRAILING BINDWEED. 
Engravings. — Bot. Reg. t. 498; and our^^. 1, in Plate 26. I 1 — 2-flowered, longer than the leaves. Bracteas linear-subulate. 
Specific Character. — Leaves cordate-ovate, cuspidate. Peduncles [ shorter than the pedicels. Calyxes ciliated. — (^G. Don.) 
Desckiption, &c. — This plant was first discovered in the Canary Isles by M. Broussonet, who supposed 
it to be a variety of C. siculus. It does indeed strongly resemble that species excepting that its flowers are 
white tinged with pink at the edges, and with the throat yellow inside. Willdenow, however, named it 
C. elongatus from the great length of the footstalks of the flowers. It is a trailing species, very hardy, and of 
the easiest culture, requiring no other care than that of sowing the seeds in the common garden soil ; but it is now 
very rarely met with in gardens. 
5.— CONVOLVULUS INVOLUCRATUS, Ker. THE LEAFY-CUPPED OR GUINEA BINDWEED. 
Enchatings. — Bot. Reg. t. 313; Bot, Mag. t. 2205; and ovx fig. 
8, in Plate 26. 
Synonymes. — 0. bicolor, Roxb. ; Ipomoea bicolor, Svjt. ; Caly- 
stegia Keriana, Swt. ; Shutereia bicolor, Choisy. 
Spfcific Character. — Stem villous. Leaves ovate-cordate, entire, 
or usually sinuately-angular. Peduncles usually 1 -flowered, bracteate, 
exceeding the leaves. Outer sepals large, involucrating the flower. — 
(G. Don.) 
Description, &c. — This is rather a remarkable species, from the very curious and leafy calyx. The flower, 
which somewhat resembles that of the Thunlergia alata, is of a pale yellow, with a deep reddish purple centre. 
The leaves are shining, but covered with fine hairs. The species is a native of Africa, but it has also been found 
in the East Indies. It was introduced in 1818, and was thought not likely to live out of the stove. It is found 
however to flower beautifully with the common treatment of tender annuals ; that is, raised in a hotbed, and 
planted out when of sufficient size. As the plant is, however, rather tender, it is best in most situations to 
transplant it in May into a pot, and not to plant out in the open ground till June. The name of a two-coloured 
Convolvulus is in Carter's catalogue, but it can hardly be the same species, as it is described as a hardy annual. 
OTHER SPECIES OF CONVOLVULUS. 
All the following species have been introduced, but, with only one or two exceptions, we do not know where 
seeds of them are now to be procured. 
C. PENTAPETALOIDES, Lin. 
This species, which is sometimes called the Majorca Convolvulus, resembles C. tricolor, but it is a trailing 
plant, and has much smaller flowers. It is a native of Majorca and the Ionian Isles, and was introduced in 
1789. 
C. STRICTUS, Lehm. 
Has white flowers tinged with pink ; and its habit of growth resembles that of C. tricolor. It is a native of 
Egypt, and was introduced in 1822. This is called the Egyptian Convolvulus.
