Dense vegetation buffers the wind so most Amazon plants are animal-pollinated. Most species such as
orchids, are visited by insects, but a significant proportion are pollinated by bats (e.g., cocoa)
or hummingbirds (e.g., heliconias). Trees pollinated by animals often have their flowers growing
directly from the trunk—a phenomenon known as "cauliflory." This tree is a species in the genus
Carpotroche (possibly C. mollis) a member of a widespread tropical family, the Flacourtiaceae.
Variation in pollination strategies is an important factor contributing to plant species diversity.
