The tribe includes more than 115 species, and it has a disjunct distribution with four genera in Central and South America and one genus in the Mascarene Islands. While the placement of this tribe within the palm classification has been controversial, the monophyly of the tribe is well supported by plastid DNA sequence data. All the genera in Chamaedoreeae are resolved as monophyletic with high support, but the relationships among genera are not fully resolved. The placement of the genus Hyophorbe and the monotypic genus Wendlandiella as sisters to the remaining genera gives new insight into the study of the evolution of solitary flowers and the dioecism within this palm tribe. Although a low substitution rate of palm plastid DNA has been widely mentioned, the results of this study show high resolution at species level, especially within the largest genus, Chamaedorea, indicating that plastid DNA is useful for the inference of relationships at low taxonomical level in some groups of palms.} }
