Introduction 
Work in progress towards an account of Olearia Moench for the "Flora of Australia" has 
revealed many new taxa. It will be some years before this project is completed. This paper 
provides descriptions of seven distinctive new species in order to make their names available lor use 
in the interim. All of these taxa arc endemic to Western Australia, and five of them are considered 
rare and/or endangered. 
It is worthy of note that O. fluvialis and O.mucronata bring the number of endemic plant 
species recorded in the Fortescue District from 65 (Sandcll et al. 1988) to 67 and the number of 
these restricted to the Hamersley Range National Park to 12.
