The east-facing flowers of Drosera tracyi

Drosera tracyi, like its sister taxon Drosera filiformis, has inflorescences that face toward the morning sun. When inflorescences were manipulated to face W vs. E, direction had no effect on pollen removal from anthers or pollen deposition on stigmas. Facing the sun, in this case, is best interpreted as an evolutionary anachronism that no longer has a function, at least not for the enhancement of pollination where D. tracyi now grows in the Panhandle of Florida and adjacent states.
