Description
The fruit of the Cocoseae is a modified drupe, with a sclerenchymatous epicarp and a highly developed mesocarp, formed mainly by parenchyma . The endocarp is generally sclerenchymatous and protects the seeds from predation and drying. The most obvious synapomorphy of the species of this tribe is the presence, in the endocarp, of three or more "eyes" or pores of germination.[1]
Distribution
The Cocoseae are distributed mainly in the Neotropical regions, with two genera endemic to Africa (Jubaeopsis and Elaeis) and Madagascar ( Beccariophoenix and Voanioala ), respectively.
