 The leaves of "B. plagiocarpa" (Dallachy's Banksia) are similar in form, shape and robustness, but differ strongly in structure.Leaves of "B. saxicola" (Grampians Banksia) are structurally the most similar to "B. kingii", but have a different shape.There also appear to be some affinities with "B. marginata" (Silver Banksia) and "B. canei" (Mountain Banksia), but insufficient to warrant the fossil's ascription to those species.
