The circumscription of species and subsequent classification into genera were reassessed for Ophiobotrys, Osmelia, and Pseudosmelia, three closely related genera of Old World Samydaceae (Salicaceae sensu lato). Phylogenetic analyses of plastid DNA data were performed and affirm the placement of these genera in Samydaceae, and a phylogenetic analysis of morphological data indicates that Pseudosmelia is nested within Osmelia. Pseudosmelia is also very similar vegetatively to one species of Osmelia and differs significantly only in the size and shape of fruit and the number of seeds per fruit. Thus, the one species of Pseudosmelia is transferred to Osmelia as O. moluccana. Ophiobotrys and Osmelia are maintained as separate genera, as there are several qualitative and quantitative differences in reproductive characters, and they occur on different continents. The number of species of Osmelia sensu stricto and their general circumscriptions concur with the assessment of Sleumer in Flora Malesiana. Keys to the genera and species are presented, as well as distributional data and lectotypifications for 13 names.

品种和随后分类到属的界限进行了重新评估Ophiobotrys，Osmelia和Pseudosmelia，旧世界Samydaceae的三个密切相关的属（杨柳意义上拉托）。进行质体DNA的数据的系统发育分析，并确认这些属中Samydaceae的位置，和形态数据的系统发生分析表明Pseudosmelia嵌套在Osmelia。Pseudosmelia也很相似无性一个物种的Osmelia并且仅在尺寸和水果的形状和每果种子数显著不同。因此，Pseudosmelia的一种作为O. moluccana转移到Osmelia。Ophiobotrys和Osmelia作为单独的属进行维护，因为它们在不同的大陆上出现在生殖特征上存在一些质和量上的差异。Osmelia sensu stricto的种类数量及其一般范围与Flora Malesiana中 Sleumer 的评估一致。提供了属和种的关键信息，以及 13 个名称的分布数据和选型分类。
