The cones of the jack pine (pinus banksiana) are serotinous, only opening when exposed to intense heat. this is an example of Serotiny.  Serotiny is an adaptation of some plants to release seeds in response to an environmental trigger, in this case, fire. The most common form of serotiny is pyriscence, that is, when the release of seeds is contingent upon the presence of heat, or fire.
