Peltanthera is a genus of flowering plants containing a single species, Peltanthera floribunda. The genus was originally placed in family Loganiaceae[3] and has since been variously placed in Buddlejaceae,[4] Scrophulariaceae,[5] Gesneriaceae,[6] or in its own family Peltantheraceae.[5][7] As of 2016, it is considered by the Angiosperm Phylogeny Group to be unplaced in any family, but within the order Lamiales,[1] while Christenhusz et al (2017) placed it in family Gesneriaceae as subfamily Peltantheroideae.[8]

The plant is a tree with opposite leaf arrangement.[3] The leaves are large and elliptic in shape. It has white fragrant flowers in a cymose inflorescence with trichotomous branches. The calyx and corolla each have five lobes, and there are five stamens. The two locules of the ovary each contain many seeds.[3]
