Morphology and ultrastructure of stigma, transmitting tissue and pollen were examined inGrevillea banksiiR. Br. (Proteaceae), a bird-pollinated shrub with stylar presentation of pollen. Stigmatic cells are not cuticularised and secrete copious lipidic exudate. Intercellular material of the thick primary walls of transmitting tissue cells stains positively for protein. The pollen exine is cavate and foveolate, but labile protein could be detected only in the thickened intine below germ pores. Self and non-self pollen ofG. banksii, germinated on the stigma, both show normal protein mobilisation and synthesis of wall material. Ectexine of germinated grains consistently appears saccate. Intra- and interspecific pollinations using five other species ofGrevilleaand one ofPersooniaas ‘foreign’ pollen sources, showed no pollen rejection at the stigma or in the upper transmitting tissue. Sporophytic control in compatibility regulation, believed most usual with stylar presentation, is inferred to be absent.
