Hasseltia is unique among Salicaceae in that the species have pseudo-axile placentation, compound umbellate inflorescences, and a pair of glands embedded in the base of the leaf blades.^[1] Formerly placed in the heterogeneous family Flacourtiaceae,^[2] Hasseltia is now classified in Salicaceae, along with close relatives Pleuranthodendron and Macrothumia, with which they are commonly confused.^[1][3][4]
