This has a milky, succulent, and extensively creeping 
rhizoma, branching into several aerial stems, which 
either twine in a left-handed spiral round the stems 
of any plant which cornes in their way, or else trail 
upon the ground. The leaves are alternate, with long 
pétioles, and their limbs between hastate and sagit- 
tate. From the axils of the leaves proceed single 
peduncles, bearing about two small bracts, and gene- 
rally one, but occasionally two or three, flowers. The 
calyx is monosepalous, but deeply divided into five 
segments, and persistent. The corolla monopetalous, 
bell-shaped, with five plaits. There are five stamens 
with awl-shaped filaments attached to the base of the
