Eschweilera alvimii is a species of canopy tree belonging to the family Lecythidaceae. It is endemic to the Atlantic Forest (Mata Atlântica) of eastern Brazil, specifically recorded in the states of Bahia and Espírito Santo.
Taxonomy and Description
The species was formally described by the American botanist Scott A. Mori in 1981. Taxonomically, it is situated within the genus Eschweilera, which is one of the most diverse and widely distributed genera in the Brazil nut family.
Eschweilera alvimii typically grows as a medium to large tree in moist, lowland forests. Characteristic of its genus, the tree produces zygomorphic flowers and woody, capsule-like fruits known as pyxidia. These fruits open by a lid (circumscissile dehiscence) to release seeds, which are often sought after by local wildlife.
Distribution and Habitat
The geographic range of Eschweilera alvimii is highly restricted. It is found exclusively in the coastal rain forests of eastern Brazil. This region is known for high levels of biodiversity but has been subject to extensive fragmentation and deforestation. The species is generally found in primary forest environments and is sensitive to significant habitat disturbance.
Conservation Status
Eschweilera alvimii is classified as "Vulnerable" (VU) by the IUCN Red List of Threatened Species. Its primary threat is habitat loss driven by agricultural expansion, urban development, and logging within the Atlantic Forest biome. Because of its limited distribution and the continuing decline in the quality of its habitat, it is a subject of concern for regional conservation efforts in Brazil.
