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
