The genus Polyalthia (Annonaceae) has undergone dramatic taxonomic changes in recent years. Nine Polyalthia species have historically been recognized in Fiji, all of which have subsequently been transferred to three different genera, viz. Goniothalamus, Huberantha and Meiogyne. The transfer of six of these species has received strong molecular phylogenetic support, although the other three species, Polyalthia amoena, P. capillata and P. loriformis [all transferred to Huberantha], have never previously been sampled in a phylogenetic study. We address this shortfall by sampling available herbarium specimens of all three species and integrating the data in a molecular phylogenetic analysis. The resultant phylogeny provides strong support for the transfer of these species to Huberantha. The taxonomic realignment of all nine Fijian species formerly classified in Polyalthia is also clearly demonstrated and supported by the resultant phylogeny. The updated taxonomic treatments of the nine species, a key to the three genera and a key to the Fijian Huberantha species are provided.

斐济“ Polyalthia”的系统发生关系

近年来，Polyalthia（Annonaceae）属发生了重大的分类学变化。斐济历史上已经认识到9种波利西亚物种，所有这些物种后来都转移到了3个不同的属中，即。鹅膏菌，Huberantha和Meiogyne。尽管其他三个物种，Polyalthia amoena，P。capillata和P. loriformis [都转移到Huberantha]，以前从未在系统发育研究中进行过采样，但其中六个物种的转移获得了强大的分子系统发育支持。我们通过采样所有三个物种的标本馆标本并将数据整合到分子系统发育分析中来解决这一不足。最终的系统发育为这些物种向Huberantha的转移提供了有力的支持。先前归类为Polyalthia的所有九种斐济物种的分类学重新排列也得到了清晰的证明，并得到了系统发育的支持。提供了这9个物种的更新分类学处理方法，这是3个属的关键物种，也是Fijian Huberantha物种的关键物种。
