ⓘ Banksia undata var. undata

Banksia undata var. undata is a shrub endemic to Western Australia.

It was known as Dryandra praemorsa VAR. praemorsa until 2007, when all Dryandra species were transferred to Banksia by Austin mast and Kevin Thiele. Since there was already a plant named Banksia praemorsa cut leaf banksia, mast and Thiele were forced to choose a new specific epithet, their choice, "undata", comes from the Latin undatus "in waves", in connection with corrugated sheets. As the autonymic variety, the varietal name was changed along with a specific name.

It grows in laterite and granite soils between Clackline and Dwellingup in the South-West of Western Australia. It blooms from August to October.

It is probably the most progressive of all dryandras.
