Leaf specimens from Late Paleocene sediments in New South Wales are assigned to a new species of Banksieaephyllum, B. taylorii. In gross morphology the leaves are indistinguishable from those of extant Dryandra formosa, and similar to a few other species of Dryandra and Banksia. The fossil specimens demonstrate that subtribe Banksiinae had differentiated by the Late Paleocene and represent the earliest record of angiosperm scleromorphy in Australia to date. The superficial placement of the stomates compared with most modern Banksiinae supports the hypothesis that xeromorphy in this group generally increased in response to the development of less mesic climates in the Late Tertiary.
