Irenodendron is a genus of flowering plants in the family Salicaceae native to northern South America.[1]
These species were previously treated as a section of the genus Laetia in the family Flacourtiaceae,[2] but the genus Laetia and its relatives were moved to the Salicaceae based on analyses of DNA data.[3] 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 lacking staminodes.[1]
