Redefinition of the orchid genus Pseudoliparis Finet, with descriptions of new species

The genus Pseudoliparis Finet is characterised by subsimilar sepals and petals, by unlobed or obscurely 3-lobed lip, auriculate basally, and by the gynostemium structure, especially by narrowly triangular, acute rostellum, subequal in length to the anther, and horn or ridge on the dorsal surface of the column part. Three new species are described and illustrated: P. curviauriculata Szlach. & Marg., sp. nov., P. raciborskii Szlach. & Marg., sp. nov. and P. van-royenii Szlach. & Marg., sp. nov. Their taxonomic affinities are briefly discussed. Additionally, 19 new combinations are proposed.
