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 In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have ...

of the species of this tribe is the presence, in the endocarp, of three or more "eyes" or pores of germination.

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.

Systematics

The Cocoseae in the sense of Dransfield et al. (2008) are identified as natural relatives (Monophylum) in most studies. Their systematic position within the Arecoideae is still unclear. Different studies see them as a sister group of the Reinhardtieae, as a sister group of the group from Reinhardtieae and Roystoneeae, or as a sister group of the Oranieae. The Tribe is divided into three sub-tribes. All three are monophyletic. Bactridinae and Elaeidinae are sister groups
