Studies in the genus Livistona (Coryphoideae: Arecaceae)

TL;DRAbstract

This thesis provides new insights into the genus Livistona based on taxonomy, cladistic analyses, molecular investigation, historical biogeography, and gender function. The taxonomic treatment recognises 35 currently accepted taxa. Four new species, Livistona chocolatina, L. concinna, L. surru and L. tothur, are described as part of this treatment. They will be formally published elsewhere. Literature research revealed that 92 names have used Livistona as part of the binomial. Of these, 68 are typified by extant herbarium specimens. Five names are typified by illustrations. Of the remaining 19 names, types were never designated. It is proposed that eleven names require typification, including Livistona saribus, Chamaerops biroo, Corypha decora, Corypha minor, Livistona altissima, Livistona hoogendorpii, Livistona jenkinsiana, Livistona spectabilis, Livistona tonkinensis, Saribus olivaeformis and Saribus subglobosus. New names are proposed for L. decipiens, which becomes L. decora, and
