Morphology Leaves
Leaflets elliptic or obovate, cuneate at the base, usually emarginate at the tip, the teeth small (up to 0·2 mm. long) and not ending in a subulate tip; main nerves 11–17 on each side at an angle of 50°–60° to the midrib.
Morphology Reproductive morphology Inflorescences
Inflorescences ±12 mm. across; peduncle up to 4 cm. long; pedicels 1·5–2 mm. long, as long as the calyx-tube.
Morphology Reproductive morphology Flowers Calyx
Calyx-tube pointed at the base, ±1·5 mm. long, the commissural nerves often divided low down or at least well below the tip; teeth 2–3 mm. long, tapering gradually.
