Seed separator

From Wikipedia, the free encyclopedia
Seed separator of Banksia marginata, with winged seeds still cohering

A seed separator is a woody structure which forms the basal ovule in the follicles of some Proteaceae.[1] In some serotinous species, this structure helps to insulate against extreme heat from fires, and allows the plant to subsequently germinate after the fire has passed.[2]
