Abstract
A new species of Chrysosplenium (Saxifragaceae), C. fallax (ser. Pilosa), is described and illustrated from Primorsky Krai, the Far East of Russia. Chrysosplenium fallax forms specialized underground stolons during budding and early flowering. The largest leaves are located at the top of vegetative shoot and have a cuneate base and pubescence on the abaxial side. The top of vegetative shoot does not take roots. The distinguishing morphological features and the differences in the seasonal development of C. fallax from the closely related C. pilosum and C. villosum (ser. Pilosa) are listed.
