Pod dehiscence and shattering
For the majority of 20 randomly sampled pods at dry maturity (Fig 3)
Legend:
Leathery podded: no dehiscence (pods will not spontanously open)
Minor shattering: weakly, tardily dehiscent, Pods will open along suture but will not twist
Excessive shattering: explosive dehiscent, Pods will suddenly twist, ejecting seeds
