摘要：

This paper provides descriptions and illustrations of two new species of Pouteria from the Atlantic forest of Bahia, Brazil (P. atlantica and P. trifida). In addition, distribution maps and a table with main characters to distinguish the new species from related taxa are also included. Pouteria atlantica is characterized by large trichomes that cover the corolla lobes, anther's outer surface, and form tufts on the apex of anthers. Pouteria trifida is distinguished by its long petioles and trifid staminodes. Due to intense deforestation in the Atlantic forest, preliminary IUCN red list assessments are provided. Pouteria atlantica is proposed in the IUCN status critically endangered (CR), while the data for P. trifida are still insufficient.
