Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations
Biotropica, Volume 57, Issue 6, November 2025.In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.
