Abstract

Begonia is the world’s fastest-growing genus and a focus of intense taxonomic research. To support this, a stable and useful sectional classification is needed. This paper reviews the feasibility and challenges of creating an infrageneric classification for Begonia based on phylogenetic data, and how to overcome phylogenetic and taxonomic conflict. In particular, it (i) tests genus-wide patterns of incongruence between phylogenies based on the nuclear, chloroplast and mitochondrial genomes; (ii) explains organelle inheritance and its contribution to phylogenetic incongruence, and (iii) presents a manifesto for a workable and stable subgeneric classification in light of the above and lays the foundation for a collaborative Begonia Phylogeny Group.

秋海棠系统发育与分类学冲突的解决

海棠是世界上生长最快的属，也是分类学研究的热点。为了支持这一点，需要一个稳定和有用的分段分类。本文综述了基于系统发育数据建立海棠非属分类的可行性和挑战，以及如何克服系统发育和分类冲突。特别是，它(i)测试基于核、叶绿体和线粒体基因组的系统发育之间的全属不一致模式;(ii)解释了细胞器遗传及其对系统发育不一致的贡献，(iii)在上述基础上提出了一个可行且稳定的亚属分类宣言，并为合作建立海棠系统发育组奠定了基础。

期刊介绍： Edinburgh Journal of Botany is an international journal of plant systematics covering related aspects of biodiversity, conservation science and phytogeography for plants and fungi. The journal is a particularly valued forum for research on South East and South West Asian, Sino-Himalayan and Brazilian biodiversity. The journal also publishes important work on European, Central American and African biodiversity and encourages submissions from throughout the world. Commissioned book reviews are also included. All papers are peer reviewed and an international editorial board provides a body of expertise to reflect the wide range of work published and the geographical spread of the journal’s authors and readers.
