Pootstock extensively creeping. Stem twining, twisted npon 
itself. Leaves thin, stalked, triangular-ovate, cordate-sagittate or 
cordate-hastate at the base, acute, entire. Peduncles axillary, 
1-flowcred. Bracteoles 2, close to the base of the calyx, very large, 
triangular-ovate, mucronate, as long as or longer than the calyx, 
sub-cordate at the base. Sepals nearly equal, lanceolate, ovate- 
acute, free nearly to the base. Corolla 5 or G times as long as 
the calyx. 
In fields, cultivated ground, hedge-banks, and waste places. 
Very common in England, local in Scotland; occurring as far

Pootstock about the thickness of a quill, white, fleshy, brittle, 
creeping horizontally, and throwing out stems at intervals. Stem 
varying much in length, often 5 feet high or more, and almost always 
climbing, simple or slightly branched. Leaves 2 to 5 inches long, 
with the lobes at the base truncate, but more approximate than 
those of C. arvensis. Peduncles longer than the leaf-stalks, but 
generally no1 exceeding the leaves, and with a pair of large green 
bracteoles tinged with pink at the apex. Flowers 2 inches across, 
pure-white, randy rose-colour, longer in proportion to their breadth 
than in 0. arvensis. Capsule sub-globular, acuminated, about \ inch
