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. Abun- 
dant in England and Ireland, but local in Scotland. /l. summer. This 
and the following species are often removed from Convolvulus as a distinct 
genus, under the name of Calystegia. 
3. ©. Soldanella; Linn. (fig. 686). Sea Convolvulus.—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 two large bracts of C. 
sepium. 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 thanin 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. 7, 
summer. 
Il. CUSCUTA. DODDER. 
Annual, parasitical, leafless herbs, with twining, thread-like stems, at- 
taching 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 
‘characters derived chiefly from the size and form of the corolla and of 
the scales, the constancy of which has not yet been satisfactorily ascer- 
- tained. : 
Corolla more than a line in diameter, with short, broad lobes, 
and inconspicuous, appressed scales. 
Calyx shorter than the corolla-tube, which is not much swollen 
when first flowering. reales ap EE Br ss . 1. C. europea,

Corolla usually less than a line in diameter, with pointed, spread-

1, C. europzea, Linn. (fig. 687). Greater Dodder.—The whole plant 
' is of a pale greenish-yellow, tending more or less to redden in many situa- 
tions. Flowers in sessile, globular clusters, 4 or 5 lines in diameter ; each 
flower a little more than 1 line in diameter, sessile or borne on an ex- 
ceedingly short pedicel. Sepals broad and rounded. Tube of the corolla 
at first broadly cylindrical, longer than the calyx, with broad and short 
lobes, and very minute, scarcely perceptible scales inside. Styles and 
stamens usually enclosed in the tube. As the capsule enlarges, the tube of 
the corolla becomes nearly globular. |
