The Sapotaceae are a significant component of the humid forests of the Neotropics and have many species of economic interest. Chrysophyllum gonocarpum is one of them and its edible fruits have currently acquired a high commercial value. Since there are no studies that cover its floral anatomy and elucidate its sexual system, the objective of the present study is to describe these aspects based on field observations and a detailed anatomical analysis of their flowers. Conventional techniques of plant anatomy are implemented. The results indicate that the species presents cryptic dioecy, showing specimens with morphologically and functionally pistillate flowers (with reduced staminodes), and trees with morphologically hermaphrodite and functionally staminate flowers. In addition, data on floral nectaries and laticiferous are provided.
山榄科是新热带地区湿润森林的重要组成部分，具有许多具有经济价值的物种。厚皮树就是其中之一，其可食用的果实目前具有很高的商业价值。由于目前还没有研究涵盖其花部解剖结构并阐明其性系统，因此本研究的目的是基于野外观察和对其花部的详细解剖分析来描述这些方面。采用了植物解剖学的常规技术。结果表明，该物种表现出隐蔽的雌雄异株现象，表现出形态和功能上为雌蕊的标本（具退化雄蕊），以及形态上为两性花和功能上为雄花的树木。此外，还提供了花部蜜腺和乳汁管的数据。
