WIND POLLINATION OF NEOTROPICAL DIOECIOUS TREES

Anemophily may be frequent in neotropical dioecious trees, of diverse taxonomic affinity, as shown here for 19 species in 13 families at one locality, on the basis of floral morphology and pollen presentation. Flower-visiting bees often are not pollinators but commensal or parasitic. The perceived scarcity of anemophily in tropical trees is brought into question by a reconsideration of the evidence regarding pollen type, nectar, weather, insect visitors, and tree density.
