Abstract

Begonia tamoiana is a new species endemic to Brazilian Atlantic Rainforest, a biome rich in endemism and species diversity, and it is described and illustrated herein. Begonia tamoiana is morphologically similar to B. magdalenensis but differs in having abaxial leaf blades with simple trichomes throughout (vs. 2-branched trichomes throughout) and ovate wings capsule (vs. triangular). A description, ecological comments, illustrations, color photographs, and a provisional IUCN conservation assessment of this species are provided. Begonia tamoiana is preliminarily classified as Vulnerable (VU) due to its very small populations and restricted distribution.
