Distribution and habitat.

Glochidion philippicum is distributed in China (only in Taiwan), Malaysia, and the Philippines. The species usually occurs beside a gravelly road, forest margins, and roadsides, at low and medium altitudes. In Taiwan, the species is widely distributed from Ilan, Taichung, Changhua and Chiayi, to Hualian, Kaohsiung, Pingtung, Tainan and Taitung.

Taxonomic discussion.

Glochidion philippicum differs from all other Glochidion species in Taiwan by its sub-hemispherical or sub-conical styles (Figure 2I ), capsules that are deeply 10-16-grooved, and persistent sub-hemispheric styles (Figure 2K ).
