Bract size affects resource availability and fruit set in a hummingbird‐pollinated plant with distyly polymorphism

Plant Biology, EarlyView.
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The
