Myrsine (Myrsinoideae- Primulaceae) in Southeastern and Southern Brazil

This work consists of the taxonomic treatment of Myrsine, Primulaceae, from the southeastern and southern regions of Brazil. All species described as Rapanea. are treated here as Myrsine. since the former has been placed in the synonymy with the latter. The genus is represented by dioecious shrubs and trees, with umbelliform inflorescences and globose, drupaceous fruits. Analysis of materials from herbaria and expeditions to collect specimens were performed. Analytical key, descriptions, notes on geographic distribution and illustrations are presented to identify the twenty three species of Myrsine found in the studied area.本研究针对巴西东南部与南部区域内的报春花科（Primulaceae）铁仔属（Myrsine）类群开展分类学处理。所有曾被发表为莱木属（Rapanea）的物种，现均被归入铁仔属，因莱木属已被处理为铁仔属的异名。该属植物多为雌雄异株的灌木或乔木，具伞形花序与球状核果。本研究通过分析标本馆馆藏材料及野外采集的标本完成相关工作，并提供了分类检索表、物种形态描述、地理分布注释及形态图解，用于识别研究区域内已发现的23种铁仔属植物。
