Meanwhile, German botanist Karl Friedrich von Gaertner had coined the name Pentadactylon angustifolium in 1807 from a specimen in the collection of Joseph Banks to describe what turned out to be the same species [REF].
The genus was reviewed by Peter Weston for the Flora of Australia treatment in 1995, and P. linearis was placed in the Lanceolata group,[REF] a group of 54 closely related species with similar flowers but very different foliage.
