Taxonomic notes:
Didymotheca cupressiformis is based on an early collection from Lake Eyre. This is the only record from S.Aust. and has not been confirmed by modem collections. The fact that one is dealing in this species with a reduced inflorescence is often only shown by the jointed stalk on which the individual flowers are borne.
