A moderately well-preserved miospore flora has been obtained from the type section of the Late Devonian Buttons beds in the southwestern Bonaparte Gulf Basin, Western Australia. It is characterised by relatively abundant specimens of Retispora lepidophyta (Kedo) Playford, 1976 and by other trilete miospore species that collectively constitute the R. lepidophyta Assemblage as defined from the lower part of the Fairfield Group of the Canning Basin, Western Australia. On this basis, the Buttons beds are datable as latest Devonian, probably within the interval Fa2d to Tn1a or early Tn1b of Belgian terminology. This palynological age determination is somewhat younger than previous, faunally based age assessments of the Buttons beds, which have suggested, not altogether unequivocally, an earlier Famennian age (i.e., doIIß-doIII, Falc-Fa2b). One new species of trilete cingulate miospores - Lophozono-triletes varionodosus - is instituted herein.
