YANO, Olga  and  BORDIN, Juçara. Ampliação do conhecimento sobre adistribuição geográficade espécies de Briófitas no Brasil. Bol. Soc. Argent. Bot. [online]. 2017, vol.52, n.2, pp.383-392. ISSN 1851-2372.

About 1.524 species of bryophytes are known in Brazil, distributed throughout the national territory. Floristic studies always reveal new occurrences, increasing the geographic distribution of several species. The aim of this work is to increase the knowledge of the geographical distribution of fifteen species of bryophytes for the states of Amazonas, Goiás, Rio de Janeiro and Rio Grande do Sul. Thirty samples were analyzed and nine species of mosses (Bryophyta) and six species of hepatic (Marchantiophyta) were identified. Two species were identified as new occurrences for the state of Rio Grande do Sul, one for the state of Amazonas and one for the state of Goiás. Eleven species have their geographical distribution expanded, being cited for the second time to the states of Amazonas, Rio de Janeiro and Rio Grande do Sul, increasing the knowledge of the geographic distribution of these taxa.

Keywords : Bryophyta; Marchantiophyta; New occurrences.
