Abstract

ABSTRACT We present novelties on the occurrence of species belonging to the tribes Marcetieae, Melastomateae and Pyxidantheae (Melastomataceae) derived from revision of herbarium material and recent collections in the Brazilian Amazon. We report the rediscovery of the type species of Comolia, known only from the original material, the first records of Appendicularia, Dicrananthera and Blakea in the states of Pará, Roraima and Rondônia, respectively, and the first record of Pterogastra in Brazil. We provide maps with the updated geographical distribution for each species based on the revision of herbarium collections available in online databases followed by manual data cleaning. Geographic location coordinates were obtained after reviewing the identities and locality information of all herbarium specimens. Most distribution records result from recent botanical expeditions within protected areas in the Brazilian Amazon. The first records of Pterogastra in Brazil expand the diversity of Melastomataceae in Brazilian flora to 59 genera. These novelties reinforce the importance of botanical expeditions throughout the Brazilian Amazon to cover the extensive spatial gaps in taxonomic knowledge in the region which should be prioritized as the focus of botanical fieldwork.

标题巴西亚马逊地区褐花蕨科不同谱系的新记录

摘要通过对巴西亚马逊地区植物标本室资料和近期采集资料的修订，介绍了在巴西亚马逊地区发生的新物种，这些物种属于Marcetieae、Melastomateae和Pyxidantheae (Melastomataceae)。报告了在原始资料中发现的Comolia模式种，分别在paraima州、paraima州和Rondônia州发现了Appendicularia、Dicrananthera和Blakea的首次记录，在巴西发现了Pterogastra的首次记录。我们根据在线数据库中现有的植物标本馆资料进行修订，然后进行人工数据清理，从而为每个物种提供最新的地理分布地图。对所有标本馆标本的身份和地点信息进行分析，得到地理位置坐标。大多数分布记录是最近在巴西亚马逊保护区内进行的植物考察得出的。在巴西首次发现的Pterogastra，使巴西植物区系的Melastomataceae的多样性扩大到59属。这些新发现加强了整个巴西亚马逊地区的植物考察的重要性，以弥补该地区分类知识的广泛空间空白，这应成为植物野外工作的重点。
