306 HE CONVOLVULUS FAMILY. 
but prostrate or scarcely climbing, seldom attaining above 2 feet in 
length. Leaves stalked, ovate-sagittate, 14 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. Corolla 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. Fl. all 
summer. 
2. C. sepium, Linn. (fig. 687). Larger B.—Rootstock creeping as 
in C. 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 im- 
mediately under the calyx, and completely enclosing it. Stigmas 
obovate-oblong. Capsule without any partition between the seeds. 
Calystegia sepium, Br. 
In hedges and bushy places throughout Europe and Russian Asia, 
except the extreme north, and in North and South America and 
Australia. Abundant in England and Ireland, but local in Scotland. 
Fl. summer. This and the following species are, on account of their 
large bracts, often removed from Convolvulus as a distinct genus, under 
the name of Calystegia. 
3. ©. Soldanella, Linn. (fig. 688). Sea B.—Rootstock creeping. 
Stems short, prostrate and scarcely twining. Leaves small, thick, 
broadly rounded or kidney-shaped, with broad, rounded or angular 
lobes at the base. Peduncles 1-flowered, with the 2 large bracts of 
C’. septum. Corolla nearly as large as in that species, of a light pink 
colour, the stigmas longer and more pointed than in C. sepium, but 
shorter and broader than in C. arvensis. Calystegia Soldanella, Br. 
In maritime sands, in the temperate regions of both the northern and 
southern hemispheres, scarcely penetrating into the tropics. Not un- 
common on the coasts of England, Ireland, and southern Scotland. 
Fl. summer. 
II. CUSCUTA. DODDER. 
Annual, parasitical, leafless herbs, with twining, thread-like stems, 
attaching themselves to the plants on which they grow by minute 
tubercles ; the small, nearly globular flowers in lateral heads or clusters. 
Calyx coloured like the corolla, deeply 4- or 5-cleft. Corolla with a 
broad tube, and 4 or 5 usually spreading lobes, and as many small 
scales inside the tube. Styles 2, distinct from the base, or, in some 
exotic species, united to near the top. Capsule globular, with 4 seeds 
in 2 cells. : 
A genus widely spread over the globe, comprising a considerable 
number of species, and still more numerous varieties, remarkable as 
showing great general similarity of aspect, but much diversity in minute _
