New series, subseries, species and subspecies of Eucalyptus (Myrtaceae) from Western Australia and from South Australia
BROOKER, M.I.H. AND HOPPER, STEPHEN D.
Three new series, six new subseries, twenty-two new species and twenty new subspecies of Eucalyptus are described. New taxa are treated in the order and nomenclature of the Flora of Australia Volume 19 (1988) from which we deviate only when we consider an updated treatment necessary. The new series Falcatae is erected and divided into two subseries, Falcatae and Decipientes. The series Micrantherae s.s. is expanded to include the new subseries Bakerianae, and a new series Balladonienses is erected. E. lane-poolei of series Curviptera is segregated in the new E. subseries Inflexae, E. caesia in the new E. series Caesiae, while E. series Orbifoliae comprises the remaining Minni Ritchi species. A new subseries Cupreanae is erected in E. series Lucasianae. Diagnostic notes on each taxonomic series are given at the head of the relevant groups of species throughout the paper. The new taxa are illustrated, except for E. ebbanoensis subsp. photina and E. marginata subsp. thalassica for which leaf colour and leaf gloss are the diagnostic characters, E. marginata subsp. elegantella and E. macrocarpa subsp. elachantha for which habit, bark characters and leaf, bud and fruit dimensions are the diagnostic characters and E. decipiens subspp. chalara and adesmophloia for which bark characters only are diagnostic. Distribution maps are provided. All the new taxa are endemic to Western Australia except for E. glomerosa and E. kingsmillii subsp. alatissima, both of which extend into the desert region of South Australia.
