The outcrossing rate was estimated for single populations of Banksia attenuata and B. menziesii by the use of allozyme polymorphisms in the endosperm. Of the 13 enzymes examined in each species, two possessed variable isozyme patterns in B. attenuata while three were variable in B. menziesii. Both species are apparently completely outcrossing. This implies that both species require the transfer of pollen between trees for successful seed set.
