A revision of Lanonia (Arecaceae, Coryphoideae, Livistoninae)

A revision of Lanonia was carried out based on morphological data. Two hundred and eighteen herbarium specimens were<br> examined and scored for 30 quantitative and 24 qualitative variables. Application of the Phylogenetic Species Concept to<br> 13 preliminary species of Lanonia resulted in recognition of 19 phylogenetic species. Of these, six are recognized as new<br> (L. honbaensis, L. honheoensis, L. kontumensis, L. montana, L. nuichuaensis, L. tenuisecta). Nomenclature, descriptions,<br> and distribution maps are provided for all species. Images of the type specimens of all new species are provided as well as<br> images of most qualitative variables.<br>
