The Philippine species of the genus Timonius present numerous taxonomic problems resulting from poorly defined species boundaries, misinterpretation of the origin of type specimens, and historical collections that often bear residual reproductive structures. Based on field observations and examination of herbarium materials, the following taxonomic amendments are proposed: conspecificity of T. philippinensis with T. finlaysonianus, and T. panayensis with T. valetonii, and transfer of T. quadrasii to Ridsdalea. This study also describes six new species from the archipelago: T. alejandroanus, T. dumagat, T. pseudoarboreus, T. ridsdalei, T. spes‐vitarum and T. stevendarwinii. Finally, T. nitidus is excluded from the Philippine flora.

菲律宾蒂莫尼乌斯（芸香科，瓜塔迪科）的分类学新颖性和变化

蒂莫尼乌斯（Timonius）属的菲律宾物种由于种质边界不明确，类型标本来源的误解以及经常带有残留生殖结构的历史收藏品而导致许多分类学问题。基于实地观察和标本馆材料的检查，以下分类提出修正案：中conspecificity T. philippinensis与T. finlaysonianus和T. panayensis与T. valetonii，并转移T. quadrasii到Ridsdalea。这项研究还描述了来自该群岛的六个新物种：T. alejandroanus，T. dumagat，T. pseudoarboreus，T。ridsdalei，T。spes-vitarum和T. stevendarwinii。最后，T。nitidus被排除在菲律宾菌群之外。
