TL;DR
This study describes the pollen features of 12 endemic plant species from Brazil's Atlantic Forest, highlighting their diversity and ecological importance.
Contribution
The study provides new morphological data on pollen grains of 12 endemic eudicots from the FLORAS Botanical Garden in southern Bahia.
Findings
Pollen grains showed variations in shape, size, and exine ornamentation.
The study contributes to understanding the morphopalynological diversity of the Central Atlantic Forest Ecological Corridor.
Diagnostic pollen features can aid in the identification and conservation of threatened species.
Abstract
The Atlantic Forest is home to about 40% of Brazil's flora. Approximately 50% of the 17,975 species occurring in this biome are endemic, and many are threatened with extinction, such as brazilwood, Paubrasilia echinata (Lam.) Gagnon, H.C.Lima, & G.P.Lewis. Despite such importance, studies to characterize the pollen morphology of this rich flora have been unevenly distributed throughout this phytogeographic domain. Therefore, we aimed to describe the pollen morphology of 12 selected endemic species of eudicots from the FLORAS Botanical Garden, a remnant of the Atlantic Forest at intermediate stages of natural regeneration in southern Bahia State, Brazil. The analyzed species were Andira fraxinifolia Benth., Cranocarpus mezii Taub., Desmodium juruenense Hoehne, Eschweilera ovata (Cambess.) Mart. ex Miers, Himatanthus bracteatus (A.DC.) Woodson, Lantana undulata Schrank, Lundia longa…
