Spinning Gum is only known from three general locations in the ACT. There was concern that the populations may have been impacted by the 2003 fires. This record confirms a healthy population at this location

The two Eucs with round blue opposite juvenile leaves and long adult leaves in ACT tall forest in Meredith Cosgrove's new book are Eucalyptus delegatensus, and (much less likely) Eucalyptus rubida. Eucalyptus perriniana is, however, noted as rare in the Mt Coronet area in Flora of the ACT. The juvenile leaves are definitely fused together. Those in photo 4 are not fused.

Hi Betty and Don,
Some of the juvenile leaves are fused including the one in the first photo. Flora of NSW states the juveniles are "usually" fused which indicates sometimes they are not and on the sample I have only the most basal leaves are fused with those further along the branches becoming separated. The trees are all around 3 metres high with the distinct copper coloured bark you can see in the second photo. The trees are at around 1400m elevation, generally too high for E. rubida and grow in heath on granite outcrops on an exposed SW face (233degrees), not really the habitat for E. delegatensis and the trees are far too small with the wrong bark for E. delegatensis. Given the fused juveniles I am pretty sure it is E. perriniana BUT it could be E. glaucescens. I will send a sample off to the herbarium for id. I no longer have your email address but if you send me an email I will send through some more photo's. Thanks, Greg.

Yes, it is not E. delegatensis. I am still not happy with it being E. perriniana when most of the juvenile leaves are not joined at the base. The common name of E. perriniana is Spinning Gum because the dead juvenile leaves stay on the stem and spin in the breeze. For a sighting as important as this one, you really need to have s specimen of atd least buds in situ, and preferably of buds and nuts. The herbarium will not accept material from the ground under the tree. The Plantnet key leads to Eucalyptus perriniana rather than E. glaucescens on the basis of the adult leaves being mostly opposite each other. Vicflora comments that these two species are differentiared by the juvenile leaves of E. perriniana being joined at the base and those of E. glaucescens not. It might even be E. saxatilis. To add to the confusion, Flora of the ACT states that the local E. perriniana does not redden.
