Novel type of bird pollination mechanism discovered in South America
Date:7/10/2014

The genus Axinaea belongs to the large, mainly tropical flowering plant family Melastomataceae (Meadow Beauty Family). Most of the ca. 5000 species in the family rely on bees for their pollination. Only about 100 are known to be pollinated by other insects or vertebrates. The flowers of Axinaea appear in clusters of few to more than twenty flowers and the petals of the different species are pink, yellow, orange or red. The stamens (male reproductive organs) stand out based on the contrasting colours of their bulbous appendages. The pollination mechanism of Axinaea had never been studied before and the researchers (Agnes Dellinger, Yannick Staedler, Jrg Schnenberger (Department of Botany and Biodiversity Research), Lena Fragner, Wolfram Weckwerth (Department of Ecogenomics and Systems Biology) from the University of Vienna, and the California Academy of Sciences (Darin Penneys) were very surprised to find that the flowers of this genus are visited by birds (mainly tanagers).

Complex "bellows" organ

Even more surprising was the finding that the birds do not feed on nectar as in most other bird-pollinated plants but consume the male reproductive organs (the stamens) while visiting the flowers. It turns out that the birds are attracted to the flowers by the conspicuous and sugar-rich stamen-appendages of Axinaea. As the birds seize a stamen, they are blasted with pollen by the stamen's complex "bellows" organ. And as the birds forage on, they deposit some of the pollen on a female floral organ (the stigma) and thus pollinate the flower.

Nutritious, sugar-rich food bodies as reward

Combining video monitoring and pollination experiments in the field with lab-based analyses of stamen structure and chemical composition, the researchers could describe the unique and highly complex pollination mechanism of Axinaea in detail. What they found is completely new to science and differs disti
