The genera Apuleia, Dimorphandra, Tachigali (Caesalpinioideae), Bauhinia, Schnella (Cercidoideae), Copaifera, Hymenaea e Peltogyne (Detarioideae) (Leguminosae) in the Serra Dourada State Park, Goiás, Brazil

Abstract A taxonomic survey of the genera Apuleia, Bauhinia, Copaifera, Dimorphandra, Hymenaea, Peltogyne, Schnella and Tachigali in the Serra Dourada State Park (SDSP) was carried out in order to contribute to the knowledge of the Leguminosae present in the Central West region of Brazil, where studies on the family are scarce. Fifteen species were found. Bauhinia was the most numerous genus with six species, followed by Hymenaea and Tachigali with two species each. Apuleia, Copaifera, Dimorphandra, Schnella and Peltogyne were represented by only one species each. An identifcation key, illustration to the taxa, and comments on their geographical distribution are provided.

摘要 本研究针对巴西中西部地区杜拉达山州立公园（Serra Dourada State Park, SDSP）内的阿普利豆属（Apuleia）、羊蹄甲属（Bauhinia）、愈创木属（Copaifera）、双荚豆属（Dimorphandra）、孪叶豆属（Hymenaea）、紫心木属（Peltogyne）、施内尔藤属（Schnella）以及球花豆属（Tachigali）开展分类学调查；鉴于该区域内豆科（Leguminosae）类群的相关研究较为匮乏，本研究旨在为该区域豆科植物的认知积累研究数据。本次调查共记录到15个物种，其中羊蹄甲属的物种数量最多，共计6种；其次为孪叶豆属与球花豆属，各含2个物种；阿普利豆属、愈创木属、双荚豆属、施内尔藤属及紫心木属各仅包含1个物种。本研究同时提供了对应类群的分类检索表、类群插图以及地理分布相关说明。
