"Banksia prionotes" × "hookeriana" hybrids have characteristics intermediate between the two parents. For example, the first putative hybrids studied had a habit "like that of gigantic "B. hookerana" ", having inherited the size of "B. prionotes", together with "B. hookeriana"s tendency to branch from near the base of the trunk. Similarly, the infructescences were like "B. prionotes" in size, but had persistent flowers like "B. hookeriana". Inflorescences and leaves were intermediate in size and shape, and bark was like that of "B. prionotes".
