Foxtail pine cones at different stages of development
Foxtail pine cones at different stages of developmentThis photo shows foxtail pine cones in different stages of development. The small, tightly closed purplish cones are the most recently formed, the ones on the right older but not yet opened, and the one in the center of the image has already opened and dropped its seeds, which are tucked at the base of the scales.
