Rare fossil twig with attached leaves and flowers of Pseudosalix handleyi, a newly recognized genus and species of the Salicaceae from the Eocene Green River Formation of northeastern Utah. Although similar to Salix in leaf architecture, unisexual flowers, and capsular fruits, this plant differs by its branched inflorescences and well-developed perianth. The fossil is interpreted to belong within the family Salicaceae s.l., as the immediate sister group to the clade containing extant Salix and Populus.
