306 THE CONVOLVULUS FAMILY. [ Convolvulus 
bud, with 4 or 5 lobes, or nearly entire. Stamens 4 or 5, 
attached near the base of the corolla. Ovary and capsule 
containing 2, 4, or 6 seeds, and often divided into 2, 3, or 4 
cells, the partitions very thin, and remaining attached to the 
central column, and not to the valves, when the capsule bursts. 
Style simple, with 2 or rarely 3 stigmatic lobes, or 2 distinct 
styles. 
An Order rather numerous in species, and widely spread over the warmer 
and temperate parts of the globe. The exotic genus Jpomea, including 
Pharbitis and Quamoclit,?often separated from it, supplies some of our 
most beautiful greenhouse and hothouse climbers. 
Stem leafy. Corolla campanulate . . 1, CoNVOLVULUS. 
Stem thread-like, without leaves, parasitical on other plants. 
Corolla nearly globular .. ‘ of op yeh 2 hee Se ee 
I, CONVOLVULUS. CONVOLVULUS, Bindweed. 
Twining or prostrate herbs (or in some exotic species erect), with alter- 
nate leaves. Sepals 5. Corolla campanulate. Style single, with 2 oblong 
or linear stigmatic lobes. Capsule with 4 seeds in 1 or 2 cells. 
A large genus, having the geographical range of the family, but more — 
especially abounding in the Mediterranean region. 
Bracts small, and placed on the peduncle at some distance from 
the flower. Stigma narrow-linear . - Ll. C. arvensis. 
Bracts large, close under the calyx. Stigma ovate ‘or oblong. 
Stem climbing. Leaves angular at the base c . 2. C. sepium.

The common blue Convolvulus minor of our gardens (C. tricolor of 
botanists) is a south European species ; the so-called Convolvulus major is 
the Ipomea or Pharbitis purpurea, a widely-spread species over the hotter 
parts of the world, probably of American origin. 
1, C. arvensis, Linn. (fig. 684). Lesser Convolvulus, Bindweed.— 
Rootstock slender, creeping underground to a great extent. Stems twin- 
ing, but prostrate or scarcely climbing, seldom attaining above 2 feet in 
length. Leaves stalked, ovate-sagittate, 1} inches long; the lobes of the 
base spreading and pointed, or angular. Peduncles axillary, usually 
2-flowered, with 2 small bracts at their fork, and a third on one of the 
pedicels, at some distance from the flower. Sepals small and broad. Co- 
rolla of a delicate pink, or nearly white, an inch or rather more in diameter. 
Lobes of the style narrow-linear. Capsule divided into 2 cells by a thin 
partition. - 
In fields and pastures, throughout Europe and central and Russian Asia, 
except the extreme north. Common, and often a troublesome weed in 
England and Ireland, but local in Scotland. #7. all summer. 
2, C.sepium, Linn. (fig. 685). Larger Convolvulus.—Rootstock creep- 
ing as in P. arvensis; the twining stems climb to the length of many 
feet over hedges and bushes. Leaves broadly ovate or triangular, pointed, 
with broad, angular lobes at the base. Peduncles bearing a single large — 
flower of a pure white, with a pair of large, leafy bracts immediately under 
.
