Abstract
A phylogenetic analysis was performed including 46 species in all six genera of the Neotropical palm tribe Geonomeae (subfamily Arecoideae) and an outgroup composed of 14 species from the Arecoideae, two Ceroxyloideae, and one Phytelephantoideae. The analysis was based on two low-copy nuclear DNA sequences from the genes phosphoribulokinase and RNA polymerase II. The two data sets were analyzed separately and in combination. Our results added support to the previously reported monophyly of the tribe. The basal node of the tribe was polytomous containing the genera Welfia and Pholidostachys. Pholidostachys formed a monophyletic group. The currently accepted genera Calyptronoma and Calyptrogyne formed a well-supported clade with Calyptronoma resolved as paraphyletic with respect to Calyptrogyne. Geonoma formed a monophyletic assemblage and two main clades within this genus were resolved, which are ideal for future phylogenetic studies. Geonoma section Taenianthera was not monophyletic and a group of three high-elevation Geonoma species was resolved. We conclude that the two low-copy nuclear regions provided an independent and non-conflicting source of characters. Future simultaneous analysis of these and other ongoing molecular as well as morphological data will allow a discussion of morphological character state evolution and a formal infrageneric reclassification of the Geonomeae.
