Banksia microphylla is an extinct species of shrub known from leaf fossils in Western Australia.[1] The leaf fossils are the first known in the genus Banksia to show extreme narrowness, at less than 1.5 mm wide.[1] They were collected from samples in the Zanthus-11 borehole, at about 38 metres (125 ft) deep, on the western margin of the Eucla Basin. It was described to the subgenus Spathulatae because of its diffusely placed stomata.[1]
