Pseudo pores help fling spores

A thick, soft plant expels its progeny in an unexpected way

Botanists have had the moss pulled over their eyes for more than a century when it comes to explosive spore discharge in a thick, soft plant that thrives in soggy places. Sphagnum’s spores don’t eject from their capsule because of the dramatic buildup of several atmospheres of pressure, but instead eject when the capsule cell walls dry and buckle, researchers report online and in an upcoming New Phytologist.
