Salix planifolia is a species of willow known by the common names planeleaf willow, diamondleaf willow, and tea-leafed willow.

Description.
"Salix planifolia" is a shrub varying in size from low and bushy, to long thickets, to a treelike form in height. The leaves are generally oval in shape with pointed tips, measuring up to 6.5 cm long. They are smooth-edged or serrated, glossy on the upper surface, and sometimes with silky hairs. The inflorescence is a catkin of flowers a few centimeters long.
"Salix pulchra", also commonly called diamondleaf or tealeaf willow and sometimes treated as a subspecies of "S. planifolia" ("S. planifolia" ssp. "pulchra"), is now treated as a distinct species.
