Pedilanthus diazlunanus (Euphorbiaceae): pollination by hymenopterans in a bird-pollinated genus
1997
Sahagun-Godinez, E. | Lomeli-Sencion, J.A.
Pollination in the genus Pedilanthus is commonly effected by hummingbirds. Pollination by vespid wasps in Pedilanthus is documented for the first time based on observations of Pachodynerus nasidens and Eumenes americanus pollinating Pedilanthus diazlunanus. An hypothesis concerning the mechanism by which hummingbird pollination was replaced by insect pollination in Pedilanthus is advanced based on observations of insects on P. bracteatus.
