1960 Palaeontol. 3 84 In miospores possessing air sacs, the mode of attachment of the ‘central body’ to the membrane constituting the air sac has been recognized as a fundamental distinction between genera.

1976 Nature 29 July 372/1 Samples suitable for palynological analysis, taken from two localities 125 km apart, yielded identifiable Permian miospores.

1992 M. Ingrouille Diversity & Evol. Land Plants 279 Spores and pollen grains <200 μm in diameter are called collectively miospores.
