ABSTRACT. Pseudotaxiphyllum subfalcatum, a species previously known only from North and South America, is found in herbarium collections from Asiatic Russia. Its identity is confirmed by molecular markers, and sequence data from GenBank also indicate the occurrence of this species in Japan. The description and illustration of Russian specimens are provided and a comparison of the three Pseudotaxiphyllum species currently known in Russia is given. Pseudotaxiphyllum elegans occurs in NW European Russia, Caucasus, Yakutia, and the Northern and Southern Far East; P. distichaceum grows in the Kuril Islands, and P. subfalcatum is found in Iturup Island (South Kuril Islands) and in the Baikal area of southern Siberia.
