Huang & Cheng (Fl. Taiwan 4: 465. 1978) stated that Gomphostemma formosana differs from G. callicarpoides only by leaf margin with coarsely serrate teeth 2-5 mm and that they may prove to be inseparable from each other. The illustration labeled G. formosana in that work is Leucosceptrum stellipilum (Miquel) Kitamura & Murata var. formosanum (Ohwi) Kitamura & Murata.
