Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

Plant Biology, EarlyView.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...
