Rubiaceae Juss. of caatinga of the APA Serra Branca/Raso da Catarina, Bahia, Brazil

The paper presents a survey of the species found in the APA Serra Branca/ Raso da Catarina, where were cataloged 21 species in eleven genera: Mitracarpus is the richest genus with four species (M. baturitensis, M. longicalyx, M. robustus, M. salzmannianus), followed by Staelia (S. aurea, S. galioides, S. virgata), Diodella (D. gardneri, D. radula, D. teres), Borreria (B. spinosa, B. verticillata), Cordiera (C. rigida, Cordiera sp.) and Guettarda (G. angelica, G. sericea). The other genera are represented by one species each, Emmeorhiza umbellata, Leptoscela ruellioides, Margaritopsis carrascoana, Richardia grandiflora e Tocoyena formosa. Were recorded three species endemic to the caatinga: G. angelica, G. sericea e M. longicalyx. In addition, M. carrascoana is the first record for the state of Bahia. Key for identification, descriptions, illustrations and comments about geographic distribution and phenology of the species are presented.

本论文对塞拉布兰卡/拉索达卡塔里纳环境保护区（APA Serra Branca/ Raso da Catarina）内的物种开展了系统性分类调研，共编目收录隶属于11个属的21个物种：其中墨帽草属（Mitracarpus）为物种多样性最丰富的属，包含4个物种（M. baturitensis、M. longicalyx、M. robustus、M. salzmannianus）；次之的类群依次为斯泰利草属（Staelia，含S. aurea、S. galioides、S. virgata）、迪奥草属（Diodella，含D. gardneri、D. radula、D. teres）、博雷利亚草属（Borreria，含B. spinosa、B. verticillata）、科迪耶拉属（Cordiera，含C. rigida、Cordiera sp.）以及盖塔达草属（Guettarda，含G. angelica、G. sericea）。其余各属均仅含1个物种，分别为伞花埃莫里奥草（Emmeorhiza umbellata）、类芦叶细茎草（Leptoscela ruellioides）、卡拉斯科珍珠草（Margaritopsis carrascoana）、大花理查德草（Richardia grandiflora）以及美丽托科伊纳草（Tocoyena formosa）。本次调研共记录了3种卡廷加（caatinga）特有物种：G. angelica、G. sericea与M. longicalyx。此外，卡拉斯科珍珠草（Margaritopsis carrascoana）为巴伊亚州（Bahia）的首次分布记录。本文同时提供了物种鉴定检索表、形态描述、物种插图，以及针对各物种地理分布与物候的相关评述。
