Notes

Eucalyptus tereticornis is a redgum. There are many redgums in Australia and they are discussed in Euclid 4th Ed., please see link below. The taxa most demanded in revegetation work anywhere are those which are widespread or locally abundant or both. Among redgums within Queensland these are mostly Eucalyptus tereticornis subsp. tereticornis, Eucalyptus camaldulensis, and Eucalyptus exserta. Within NSW, Eucalyptus blakelyi and Eucalyptus chloroclada are often utilised.

Our areas of operation have been from north of Mackay to northern NSW and here we've interacted with Eucalyptus tereticornis subsp. tereticornis on sands to shallow, skeletal soils to heavy cracking clays and deep alluviums, and on many geologies including basalt, andesite, metamorphics such as mudstones, and on granites etc. We observe morphological and behavioural variation in E.tereticornis which is of importance to seed collectors. The taxon may vary greatly in height and form making it easier or harder to work with, it may hold ripe seed for six weeks in some settings or for over a twelve months in others, it may set fruit in correlation with local edaphic factors (rock units, soil types) or in correlation with elevation and soil type despite seperation by hundreds of kilometres. Seed setting may be correlated with particular drainage systems as years and fruiting seasons pass. We also note variability in seed morphology, not yet described, and this variability may be erratic over small distances. In some places where the range of E.camaldulensis and E.tereticornis become close or overlap there may be intergradation occuring which could be confusing.

Historical Notes

Distribution

"Widespread along the coast and adjacent hills and plains of eastern Australia from south coastal New South Wales to Queensland where it occurs inland almost to Roma, Alpha, Charters Towers and Mt Surprise although not north of Cooktown; also in New Guinea." (Brooker, M.I.H., and Kleinig, D.A., 2004)
