Abstract
A revision of the Australian taxa of the genus Spergularia (Caryophyllaceae) on the basis of herbarium material, field studies and analysis of morphological characters necessitates realignment of some taxa and application of some neglected names, clarifying circumscription and understanding of the species of this genus. Eleven species are here recognised, with five considered indigenous, Spergularia nesophila and S. diandroides described as new and S. tasmanica transferred to Spergularia from Lepigonum. Fruits and seeds provide compelling diagnostic characters in this genus and are used in supplementary dichotomous and tabular diagnostic keys. Scanning electron micrographs (SEMs) illustrate key seed shape and surface features.

For access to specimens we thank the Directors and staff of the following Australian and European herbaria: AD, BRI, DNA, HO, MEL, NE, NSW, PERTH, BM, CHR, G, K, LD, LINN, P and UPS. The scanning electron micrographs were prepared by Cathy Miller, with some supplementary images by Rosemary White; and Andrew Whiting assisted with generation of the maps. Richard Rabeler and an anonymous referee made helpful and encouraging comments that improved an earlier version of the paper.
