All the leaves are ternate (meaning in threes) and obovate (broadest nearer the end) tapering to a point at the tip. The flowers are between 9 and 12mm long. There might be the beginnings of seed pods in the lower left - the densely hairy objects.

The leaves are hairy and on short stalks. The non-woody stems are ribbed/grooved (whichever is your pleasure).

Flowers pea-type. The seed pods are 15-25mm long, are densely hairy and contain between 3 and 6 seeds. The pods burst open when the seeds are ripe with some force, flinging the few seeds a few metres. A mature plant can produce up to 10,000 seeds every season.
