Pentaphylax euryoides (Chinese: 五列木; pinyin: wu lie mu) is a species of flowering plant in the Pentaphylacaceae family.

It is a shrub or small tree native to southern China, Vietnam, Laos, Peninsular Malaysia, and northern Sumatra.

[1] In China, it is found in Guangdong, Guangxi, Guizhou, Hainan, and Yunnan provinces, and in southern parts of Fujian, Hunan, and Jiangxi.

[3] Pentaphylax has often been placed in its own family, the Pentaphylacaceae, separated from the Theaceae or Ternstroemiaceae based on the structure of the anthers and, arguably, the ovules.

[4][5] The taxonomic placement of this species and the family has varied, due mostly to a shortage of information.
