Abstract

Telmatoblechnum, with the species Telmatoblechnum serrulatum (Blechnaceae), is recorded for the first time for the Uruguayan flora. The species, so far known from southern Brazil and Northeastern Argentina as its southernmost distribution limit, was collected for the first time in crevices between rocks of basalt and sandstone in a small hill in Uruguay (Rivera). Its morphological characteristics and the novel habitat for the species are included; photographs, a map with the location of the new record, as well as a key to the genera of Blechnaceae in Uruguay are provided.
