摘要有关保护行动和物种分布的信息是基于科学收藏和分类研究中收集和保存的标本。在热带地区，这些数据可能有几个原因。即使在已被充分探索的地区，如大西洋森林，仍然有很多关于属和物种的分布和进化的知识。在过去的15年里，在大西洋中部森林的密集采样工作，导致了6个新种的描述Bertolonia（Mendriataceae）。狭瓣波托洛尼亚Bertolonia angustipetala、狭瓣波托洛尼亚B. cuspidata，B. linearifolia，B. reginatoi和B. vitoriana为巴伊亚南部特有种，B. kollmannii也发生在米纳斯吉拉斯，靠近两个州的边界。最近在Bertolonia的这些和其他发现将该属的多样性中心从大西洋森林的南部转移到中部地区，并为了解该属内的形态和地理变异提供了新的背景。
Abstract Information regarding conservation actions and species distribution are based on specimens collected and deposited in scientific collections and taxonomic studies. In the tropics, these data might be biased for several reasons. Even in well-explored regions, such as the Atlantic Forest, there is still a lot to learn regarding distribution and evolution of genera and species. Intense sampling effort during the last 15 yr in the central Atlantic Forest has led to the description of six new species of Bertolonia (Melastomataceae). Bertolonia angustipetala, B. cuspidata, B. linearifolia, B. reginatoi, and B. vitoriana are endemic to southern Bahia, and B. kollmannii also occurs in Minas Gerais, near the border between both states. These and other recent discoveries in Bertolonia shift the diversity center of the genus from the southern to the central region of the Atlantic Forest, and provide a new context to understand morphological and biogeographical variation within the genus.
