Abstract This study comprehend the floristic treatment of Chrysobalanaceae from the state of Rio de Janeiro. Twenty-eight species, arranged into seven genera, are recorded. Two species, Licania arianeae and L. belemii, are herein first reported for the state. Descriptions, photographs, illustrations, identification keys, distribution maps and comments are provided based on fieldwork and analysis of herbarium specimens. Among the 92 municipalities in the state of Rio de Janeiro, three stand out for the diversity of Chrysobalanaceae (Rio de Janeiro, Mangaratiba and Petrópolis), while in 47 of them, there are no records of Chrysobalanaceae. The Metropolitan Region has the largest number of specimens collected, as opposed to the Northwestern Region with the smallest number.

摘要 本研究针对里约热内卢州（Rio de Janeiro）的可可李科（Chrysobalanaceae）开展植物区系处理。本次共记录该科下7个属共计28个物种。本文首次在该州报道了腺蕊花属（Licania）的两个物种：L. arianeae与L. belemii。本研究基于野外考察与标本馆标本分析，为该科物种提供了形态描述、照片、分类图解、鉴定检索表、分布地图及物种评述。在里约热内卢州的92个市镇中，有3个市镇的可可李科物种多样性最为突出，分别为里约热内卢市、曼加拉蒂巴（Mangaratiba）与佩特罗波利斯（Petrópolis）；另有47个市镇尚未有可可李科的分布记录。该州都会区的标本采集量最多，而西北部区域的标本采集量最少。
