Irenodendron M.H.Alford & Dement 2015
plant genus in the salicaceae family
Irenodendron is a genus of flowering plants in the family Salicaceae native to northern South America. These species were previously treated as a section of the genus Laetia in the family Flacourtiaceae, but the genus Laetia and its relatives were moved to the Salicaceae based on analyses of DNA data. Irenodendron was later hypothesized to be more closely related to the genera Ryania, Trichostephanus, and Piparea due to the presence of an apically divided style, and wood with dark heartwood and large rays; it differs from those genera in having cup-shaped bracts under the flowers and in

Macrothumia M.H.Alford 2006
plant genus in the salicaceae family
Macrothumia is a genus in the willow family Salicaceae with a single species Macrothumia kuhlmannii. It is a tree native to the states of Bahia, Espírito Santo, and Minas Gerais in Brazil. Formerly classified in the genus Banara in the family Flacourtiaceae, phylogenetic analyses based on DNA data indicate that this species, along with its close relatives in Ahernia, Hasseltia, and Pleuranthodendron are better placed in a broadly circumscribed Salicaceae. Macrothumia differs from its close relatives in having a congested fascicle- or umbel-like inflorescence and a large (>3 cm diameter)
