中国番荔枝科暗罗属及相关类群概述

Synopsis of Polyalthia Blume and Related Genera (Annonaceae) in China

摘要:

广义暗罗属(Polyalthia Blume)是热带亚热带森林的重要成分之一，同时也是一个分类极为困难的木本大属。《中国植物志》和Flora of China曾收录该属17种。基于最新分子系统学与分类学研究结果，对中国分布的番荔枝科(Annonaceae)广义暗罗属在属级水平的归属进行了系统梳理，结果表明，中国所有记录的暗罗属物种应置于狭义暗罗属、异萼花属(Disepalum Hook.f.)、细基丸属(Huberantha Chaowasku)、弯瓣木属(Marsypopetalum Scheff.)、单籽暗罗属(Monoon Miq.)、文采木属(Wangia X. Guo & R.M.K. Saunders)、征镒木属(Wuodendron B. Xue, Y.H. Tan & Chaowasku)、疣叶木属(Polyalthiopsis Chaowasku)和海岛木属(Trivalvaria Miq.)等9属中；提供了中国曾有记载的广义暗罗属物种名称与最新接受名的对照表，以及上述9属间的系统发生关系图，并提供了这9属及其国产物种的物种水平检索表。对中国暗罗属及相关类群的系统整理有助于深化对中国番荔枝科属级水平多样性的认识与理解。

Abstract:

Polyalthia s.l. is an important component of tropical and subtropical forests. Meanwhile, it’s a large taxonomically difficult genus of trees or shrubs in Annonaceae. There are 17 Polyalthia species in China according to Flora Reipublicae Popularis Sinicae and Flora of China. The most updated phylogenetic and taxonomic studies of Polyalthia were reviewed and summarized, and it was confirmed that the Polyalthia species previously recorded in China belong to nine genera, viz. Polyalthia s.s., Disepalum, Huberantha, Marsypopetalum, Monoon, Wangia, Wuodendron, Polyalthiopsis and Trivalvaria. An updated list of Polyalthia species recorded in China was provided with their accepted names. An illustrated phylogeny was provided to show the phylogenetic relationship of the nine genera. An identification key to the nine genera and related species in China was also provided. This synoposis of Polyalthia and related taxa in China would be helpful to deepen the understanding on the generic diversity of Annonaceae in China.
