Seed Dispersal

  1. Water; Floating in saltwater currents; Method not stated; (Murray, 1986); Diaspore=seed. The diaspore is buoyant.
  2. Unassisted; Seeds drop to the ground close to or beneath the parent plant; Method not stated; (Moreno-Casasola et al., 1994); Diaspore=seed. Pods are dehiscent.
