Margonska, H. B. 2003: Materials towards a revision of the genus Pseudoliparis (Orchidaceae, Malaxidinae), 1. — Ann. Bot. Fennici 40: 63–66.

One new combination at the section level and nine combinations at the species level are proposed in the genus Pseudoliparis (Orchidaceae, Malaxidinae).

Keywords: Malaxidinae, nomenclature, Orchidaceae, Pseudoliparis, taxonomy
