The mature seeds of P ovata have a deep scar on the ventral side for this species we suggest that it is more appropriate to describe the mechanism as an expansion rather than an extrusion similar to the extension of a concertina where the mucilage starts to expand into the aqueous environment as it hydrates from the wrinkled appressed
