Euc. Tereticornis vs. Camaldulensis - are they different?

[Ces]

Hello Ausbonsai community,

I have a fairly obscure question that I hope some people on the forum may be able to help me answer. The more I read on this topic, the more confused I get.

I would like to know if there is a difference between Eucalyptus Tereticornis and Eucalyptus Camaldulensis species?

I have read (In several different documents and stated different ways) that either Camaldulensis was previously called Tereticornis or that the two species were recently differentiated. I'm intertested because I have 20 'Tereticornis' tubers that I have grow on plans for. The reason I got them however is that the most beautiful gum in nature that I know was identified to me as a Tereticornis.

Would love to hear anyone's thoughts on this.

Cheers,

Ces.

The short answer is "Yes", according to what I've read. In taxonomic analysis there is no talk of E. camaldulensis when describing E. tereticornis, and vice versa. See good old Wikipedia: http://en.wikipedia.org/wiki/Eucalyptus_tereticornis
What may be confusing is the fact that in forestry E. tereticornis has been hybridised with E. camaldulensis "to remediate saline and sodic soils". See http://www.florabank.org.au/lucid/key/s ... cornis.htm

They are not synonymous.

Thanks for the clarity guys andthe links LLK.

Educating yourself is the only way to learn in this craft but you've got to be careful about what you read on the 'interweb'.

They are not the same taxon - similar looking yes - but pretty much always regarded as two different entities. There is an article somewhere in the journal Australian Systematic Botany within the last decade that covers this topic. Good luck with your trees, Ash

Hi guys,

It was at some stage considered to be a subspecies of E. camaldulensis by some botanists. APNI is a website that lists all the suggested names for a taxa and the author. http://www.anbg.gov.au/cgi-bin/apni Search for Eucalyptus tereticornis and you will find an amazing number of suggestions. The genus Eucalypt is still very widely debated.

A botanical description of every plant native to NSW can be found at PlantNet.
Eucalyptus tereticornis: http://plantnet.rbgsyd.nsw.gov.au/cgi-b ... reticornis
Eucalyptus camaldulensis: http://plantnet.rbgsyd.nsw.gov.au/cgi-b ... aldulensis
Key to identifying species in the genus Eucalyptus: http://plantnet.rbgsyd.nsw.gov.au/cgi-b ... Eucalyptus

The two appear to be quite different from the descriptions.

Also, just a quick note; the species is never capitalised i.e. Daphne odora, Banksia serrata, Pinus radiata, Ulmus parvifolia etc.
