CHAPTER XXVII. 
CONVOLVULACE^. 
EssEKTuL Character. — Calyx of 5 sepals, rarely 5-tootbed, per- 
sistent. Cctrolia monopetalous. Limb of five plaits oi bve lubesi 
with a twisted seslivation. Stamens 5, ejiipctalous. Hypngynons disk 
annular, surrounding the ovarium. Capsule deliiscing valvately, rarely 
transversely. Seeds rounded on one side, and flattened on the other. 
Albumen mucilaginous. Cotyledons corrugated. — Usually twining 
herbs. Leaves alternate, entire or lobvd. Peduncles axillary or 
terminal; one or many flowered. — (G. Don.) 
Description, &c. — The Convolvulaceae are all twining plants, most of which are herbaceous, and many of 
these annuals. They have all large showy flowers, and are of very easy culture. According to modern botanists, 
there are thirty-five in the order Convolvulaceae, most of which contain annuals ; but we shall confine ourselves 
to the two genera Convolvulus and Iporaoea (both of which were instituted by Linnaeus), as under these names 
the plants are best known, and we shall only indicate the new names in the synonymes.

CONVOLVULUS, Choisy. THE CONVOLVULUS OE BINDWEED. 
Lin. Syst. PENTANDRIA MONOGYNIA. 
Generic Character Stamens inclosed. Stigma 2-lobed ; lobes terelely filiform. 
Description, &c. — The name of Convolvulus was given by Linnaeus to a number of climbing, showy- 
flowered plants, which since his time have been divided into five or six dificrent genera ; but to prevent 
confusion, we shall describe these plants under their old name of Convolvulus, which alludes to the folding of the 
flowers in the bud.

Engravings — Bot. M:ig. t. 27, and out fig. 2, in Plate 26. 
Synonymf, — Convolvulus minor, Hori. 
Specific Character, — Stem declinate, terete, beset with small, 
Bofb, white hairs. Leaves ovate-lanceolate, spatulate, hairy, ciliated. 
Peduncles I-flowered, bibracteate, longer than the leaves. Sepals 
ovate-lanceolate, acute. — (G. Don.) 
Description, &c. — A beautiful flower with three distinct colours, yellow, blue, and white, well known 
under the name of Convolvulus minor, or the dwarf Convolvulus, in our gardens. There are two varieties of it, 
one white, and the other striped, but they do not always come true from seed. The species is a native of Spain, 
Portugal, Sicily, and the north of Africa ; and it was introduced by Parkinson before 1829 ; as he calls it the 
small blue Spanish Bindweed in his Paradistts, and says he had the seed of " Guillaume Boel," who brought it 
from Por-tugal. Some botanists suppose this species to have been originally only found in Barbary ; but whether 
introduced or indigenous, it is now a common weed both in Spain and Portugal. The flowers always folding in
