To test this hypothesis, we used the model dynamics of a single valve to obtain the ballistic trajectories of seeds explosively dispersed away from the parent plant. Webtheir seeds, in a manner similar to some genera in the Euphorbieae (Forster 2007). These descriptions obscure the actual mechanism by which capsules of many Viola species open and how the seeds are subsequently dispersed. Other workers describe how seeds are released from the capsule, e.g., "explosively ejected", "ballistically dispersed", or
