BeyondGenera Palmarum: progress and prospects in palm systematics

The systematic biology of the palm family (Arecaceae) is probably better known than that of any other tropical plant family of comparable size. As a result, the palms are now regarded as a model group for tropical rain forest research. Ten years ago, the first phylogenetic classification of palms was established as a foundation for the second edition of the palm systematic synthesis, Genera Palmarum (GP2), which was published in 2008. Here, we review progress in palm systematics since GP2, summarizing the latest developments in an updated palm classification and schematic phylogenetic tree. To date, the palms comprise 181 genera and c. 2600 species. In just 8 years, six new genera and 200 new species have been described, whereas eight genera have been sunk into synonymy. This reflects the highly dynamic nature of systematic discovery of palms at both forest and phylogenetic frontiers. Palm phylogenetics is a vibrant field, with new trees being generated and utilized in increasingly innovative and ambitious ways. Existing understanding of relationships among the five subfamilies has been confirmed and deep nodes in the subfamilies are crystallizing, especially in subfamilies Arecoideae and Coryphoideae. We conclude that palm systematic knowledge is far from complete and that tools, such as GP2, only stimulate further scientific research and discovery. Despite recent advances, however, many aspects of the palm Tree of Life still remain scarcely known. The vast datasets that the phylogenomic revolution is now bringing to bear on palms promise to elucidate many of these unknowns. The ultimate goal, a species-level phylogenetic tree for palms, is now coming within reach.

“…In spite of the completion of a monograph of the betel nut palm genus Areca (Arecaceae) in East Malesia (Heatubun et al 2012), new species Areca within this area are still being discovered (Heatubun et al 2013). During two recent expeditions to Yamor Lake, Kaimana, West Papua Province, Indonesia, a further new species was found, which is described here.…”

For practical use and as aid in identification of species of Areca in western New Guinea, an updated identification key is provided, based on the key produced for species of Areca in East Malesia (Heatubun et al 2012) with some modification to accommodate the two species described since that account, A. unipa (Heatubun et al 2013) and A. jokowi.…”

“…The discovery of another distinctive new species closely related to the domesticated betel nut palm, Areca catechu, draws further attention to western New Guinea as a potential area of origin of this economically important and widespread species (Heatubun et al 2012, Heatubun et al 2013. The most immediate concern, however, is the need to protect these important crop wild relative species from extinction risk and threats of habitat loss, due to landuse change, deforestation and forest degradation, over harvesting and even climate change.…”

A new species of betel nut palm, Areca jokowi, is described and illustrated here. This is the third species of Areca to have been described recently from New Guinea that is closely related to the widespread, economically important species A. catechu, the cultivated betel nut palm. A discussion of its morphological characters, distribution, ecology, habitat, uses and conservation status is provided, as well as a new identification key for western New Guinean Areca.

The palm genus Areca is widespread in tropical Asia and includes the economically important betel nut palm, A. catechu. The genus has three centres of high species diversity: the Sunda Region, the Philippines and East Malesia (to the east of Wallace's line). The taxonomy of the genus in East Malesia has been neglected. Prior to this study, 19 species were accepted for this area, all but one endemic, but their limits and differences were not understood. Here, we provide a taxonomic monograph of East Malesian Areca spp., based on an extensive study of the genus in herbaria and in the field. We recognize six species of Areca in East Malesia, including the widespread cultivated A. catechu. Five wild species are accepted, namely A. macrocalyx, A. mandacanii, A. novohibernica, A. oxycarpa and A. vestiaria. We place 12 of the previously accepted species into synonymy, and provide additional new synonymy in A. catechu. © 2011 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 168, 147–173.
