Abstract
Corydalis pumila is a species rarely observed in Poland, only in north-west part of the
land. It was known only from 11 localities in 2001 and in the Polish Red Data Book of Plants the
species was recognized as vulnerable in the country. The paper presents 20 new localities of
Corydalis pumila in Western Pomerania. The species has very rich populations in the Parsęta
river basin. It was observed also on new locality on the Krąpiel river. Survival of the species is
dependent on preservation of natural or semi-natural oak-hornbeam forests on the slopes of the
valleys. Prospects of such habitat in Western Pomerania may be pretty good thanks to Natura
2000 network.
