Differs from the European plant only by having the faces of the fruit 
usually concave. 
In this plant the usual joint in the pedicels is placed quite close to the 
flower; in P. dumetorum the joint is very near the base of the pedicel, i. e. 
the base of the flower is prolonged so as apparently to form the greater part 
of the footstalk ; in P. pterocarpum the joint is placed at about the middle.

Stem twining, branched, with scabrous ribs. Leaves stalked, cordate, with a 
lengthened acute point. Stipules short, blunt. Flowers in rather small 
axillary racemes, or 2 or 3 together in the axils of the upper leaves, the 
segments of the calyx blunt and winged, pedicels elongated; when in 
fruit recurved and jointed about the middle. Fruit triangular, its faces 
elliptical, acute at both ends, its angles blunt, opake, minutely granulated 
throughout, quite covered by the enlarged calyx, each segment of which
