Biology: Not Applicable

Taxonomic notes: Hitherto, since Bentham, invariably placed in a distinct genus, Polypompholyx, with 1 other species in. W.Aust. However, for several reasons, especially the recent discovery of a species which is in some ways intermediate between the 2 genera it seems desirable to unite them.
