豆科植物系统学家在了解豆科植物（开花植物的第三大科）的进化关系方面取得了很大进展。随着系统发育的图景变得更加清晰，对这个科的重新分类的需求也越来越大。将家族划分为三个亚家族和42个部落是过时的，并且在进化上具有误导性。传统上公认的三个亚科，沙蝇亚科，拟蝇亚科和凤蝶亚科，并不能充分代表科内的关系。2013年1月在南非约翰内斯堡举行的第六届国际豆科会议以“建立新的豆科植物分类体系”为主题，为制定新的分类提供了动力。根据目前的系统发育结果和一套原则和准则，在会议之前编写了一份分类草案，作为讨论的基础。在会议上提出并讨论了原则、指导方针和分类草案。讨论的目标是就指导分类发展的原则达成共识，讨论分类草案的优点和缺点并提出修订建议，确定在分类出版之前必须解决的系统发育缺陷并确定其优先次序。本文描述了一大批豆科系统学家的合作过程，以豆科系统发育工作组的名义发表，以开发一个新的豆科系统发育分类系统。本文的目的是告知更广泛的豆科社区和其他人，需要修订分类，并清楚地阐明该科的新分类系统的替代方案和挑战。(c) 2013年萨博。Elsevier B.V.版权所有。
Legume systematists have been making great progress in understanding evolutionary relationships within the Leguminosae (Fabaceae), the third largest family of flowering plants. As the phylogenetic picture has become clearer, so too has the need for a revised classification of the family. The organization of the family into three subfamilies and 42 tribes is outdated and evolutionarily misleading. The three traditionally recognized subfamilies, Caesalpinioideae, Mimosoideae, and Papilionoideae, do not adequately represent relationships within the family. The occasion of the Sixth International Legume Conference in Johannesburg, South Africa in January 2013, with its theme "Towards a new classification system for legumes," provided the impetus to move forward with developing a new classification. A draft classification, based on current phylogenetic results and a set of principles and guidelines, was prepared in advance of the conference as the basis for discussion. The principles, guidelines, and draft classification were presented and debated at the conference. The objectives of the discussion were to develop consensus on the principles that should guide the development of the classification, to discuss the draft classification's strengths and weaknesses and make proposals for its revision, and identify and prioritize phylogenetic deficiencies that must be resolved before the classification could be published. This paper describes the collaborative process by a large group of legume systematists, publishing under the name Legume Phylogeny Working Group, to develop a new phylogenetic classification system for the Leguminosae. The goals of this paper are to inform the broader legume community, and others, of the need for a revised classification, and spell out clearly what the alternatives and challenges are for a new classification system for the family.
