Abstract

Eleven plants of Asplenium platyneuron (ebony spleenwort) were found in disturbed serpentine woodland in south-central Slovakia (Central Europe). This find represents a new addition to the fern flora of Europe. It is probably the result of long-distance spore dispersal. The nearest known sites for this species are those in eastern North America, about 6500 km away. The important determination characters of A. platyneuron are described, the Slovakian locality characterized and an overview of the ecology and a map of the worldwide distribution of this species provided.
