  • There is a plant whose flowers bloom almost underground--and that might be how it lures in its favorite pollinators, mushroom-eating flies. The cast-iron plant (Aspidistra elatior) has drab flowers that are often buried in leaf litter. Biologists have long been puzzled about how these subterranean flowers are pollinated. Slugs, small crustaceans and insect-like springtails have all been named as possible candidates. To find out Kenji Suetsugu at Kobe University and Masahiro Sueyoshi at the Forestry and Forest Products Research Institute in Tsukuba studied wild cast-iron plants. While many species visited, fungus gnats were the best pollinators. These small, mushroom-eating flies adeptly navigated the flower's petals and the flowers they visited made the most fruit
