Abstract

OSTROSKI, Piera; SAITER, Felipe Zamborlini; AMORIM, André Márcio  and  FIASCHI, Pedro. Endemic angiosperms in Bahia Coastal Forests, Brazil: an update using a newly delimited area. Biota Neotrop. [online]. 2018, vol.18, n.4, e20180544.  Epub Aug 16, 2018. ISSN 1806-129X.  http://dx.doi.org/10.1590/1676-0611-bn-2018-0544.

The forest along the coast of Bahia state, in northeastern Brazil, has been acknowledged as an area of endemism for several groups of organisms. The first study concerning endemic angiosperm species in this region, through which 395 taxa were registered, was conducted 15 years ago. However, this number is probably underrated. In this article, we present an updated checklist of angiosperm taxa in Bahia Coastal Forests (BCF) based on geographic distribution data available from the Brazilian Plant List (Flora do Brasil 2020). The records were checked in herbaria, recent taxonomic literature, and, when necessary, reviewed by experts. The final checklist consists of 547 taxa endemic to BCF, distributed in 69 families, with seven endemic genera: Bahiella (Apocynaceae), Santosia (Asteraceae), Harleyodendron (Fabaceae), Cubitanthus (Linderniaceae), Anomochloa and Parianella (Poaceae), and Andreadoxa (Rutaceae). The families with highest richness in endemic taxa were Bromeliaceae (108 spp.), Fabaceae (41 spp.) and Myrtaceae (32 spp.). This updated checklist shares only 143 taxa with a previous list published about 15 years ago. Those two lists differ mostly due to slightly different area limits, and to the large number of additional endemic species described since then. We hope our list will be used as a resource in future studies and contributes to the conservation of the highly diverse Bahia Coastal Forest.
