Similar to O. japonica Blume, but distinguished from the latter by the terete, densely hirtellous stems (vs. stems subterete to slightly compressed, glabrous or with 2 hirtellous or pilosulous lines), the usually persistent and ciliate stipules (vs. caducous glabrescent stipules), the well-developed colleters inside the base of stipule (vs. without colleters), the shorter corolla tubes (8 - 9 mm vs. 9 - 14 mm) and the shorter stamens and styles (longistylous flower: 2.5 - 2.7 mm and 7 - 8 mm vs. 4.5 - 5.5 mm and 9 - 11 mm; brevistylous flower: 3.6 - 4.2 mm and ca. 2.5 mm vs. 4.5 - 5 mm and ca. 3 mm).	en	Yang, Chuan-Dong, He, Xuan-Ze, Gou, Guang-Qian (2018): Ophiorrhiza guizhouensis (Rubiaceae), a new species from Guizhou Province, southwestern China.
