APC Comment:Possible hybridisation occurs between C. lenziana and C. eremaea and between C. lenziana and C. terminalis ('C. opaca'). Eucalyptus symonii is sometimes included within C. lenziana and sometimes within C. eremaea. Records from NT and SA of E. symonii are included here. However, if E. symonii is considered synonymous with C. eremaea then C. lenziana is from WA only.
