The butterfly shaped keel flowers are among the most successful pollination syndromes in angiosperms. These flowers steer the mechanical interaction with bees and thus are hypothesized to accelerate pollinator driven diversification. The highly labile evolution of keel flowers in Papilionoideae (Fabaceae) provides a suitable system to test this hyp...
Background
The "Serra da Concórdia" is part of the Atlantic Forest phytogeographical domain in the Brazilian state of Rio de Janeiro and it has a predominant phytophysiognomy of Semideciduous Seasonal Forest. This region underwent intense habitat loss and fragmentation during the 19th century, due to coffee plantations and later pastures. With the...
Background
The Atlantic Forest is one of the most diverse and threatened phytogeographical domains in the world. Despite that, it includes regions with poor floristic knowledge, even in protected areas. Although the importance of protected areas in conserving the Atlantic Forest hotspot is undisputed, it is necessary to recognise the floristic rich...
The Reserva Biológica do Tinguá (REBIO Tinguá) is a protected area in the state of Rio de Janeiro comprising around 26,000 ha of Brazilian Atlantic Forest. We present an updated floristic inventory of Leguminosae tree species in the REBIO Tinguá. Pre-existing herbarium collections and field expeditions carried out in 2021 and 2022 were used as the...
The adaptations of plants to different environments are closely related to their wood anatomical traits. This study investigated the wood anatomy of a montane forest community and compared it with anatomical data from three other areas in the Atlantic Forest biome (montane and lowland forest). Samples from 23 montane forest species were processed a...
Despite recent advances in revealing the evolutionary history of speciose tropical plant clades, many species radiations are still poorly understood phylogenetically. One of these is the species-rich neotropical genus Tachigali (~ 90 spp.), a caesalpinioid legume lineage of mostly ant-housing canopy trees that has diversified in the tropical rainfo...

Molecular phylogenetic studies focused on the early-branching papilionoid legumes have revealed many new clades and supported several generic realignments, yet the monophyly of some of the constituent genera has remained unassessed. This is the case for the Amazonian genus Clathrotropis of the tribe Ormosieae. The genus, as traditionally circumscri...
Monopteryx is a florally divergent genus of Dipterygeae, an early-branching papilionoid legume clade largely marked by winged papilionate floral architecture, expanded upper calyx lobes often assuming a wing-shaped orientation, and petals differentiated into standard, wings, and a keel enclosing the basally connate stamens. In contrast to the remai...
The early-branching clades of Fabaceae subfamily Papilionoideae are characterized by their remarkable lability in floral architecture. In contrast, more derived papilionoid lineages are marked by evolutionary conservatism towards strongly bilateral, papilionate flowers. Here, we show an unexpected example of conservatism of a unique floral architec...

We present a taxonomic synopsis of Aldina (Leguminosae, Papilionoideae), a poorly known Neotropical genus of predominantly Amazonian trees with unusual, non-papilionate flowers. Aldina is characterized by the combination of odd-foliolate leaves and flowers with radial symmetry, free and undifferentiated petals, an entire calyx, and free, numerous s...
Sucupira-branca is a popular name for the papilionoid legume tree genus Pterodon (Leguminosae, Papilionoideae), which is amply distributed across South American savannas and seasonally dry tropical forests. Pterodon has been strongly supported as monophyletic in all molecular phylogenetic analyses and stands out within the Dipterygeae clade by the...
The Brazilian Atlantic Forest domain has one of the highest levels of plant species endemism, but the intense historical fragmentation across the coastal Atlantic tropical rain forest has reduced the original vegetation to < 10% and an island-like, patchy landscape. Despite such unprecedented vegetation loss, biogeographically and phylogenetically...
