Hi Thomas @thebeachcomber , I am a little confused by the combining of Corymbia henryi with Corymbia maculata. I can understand the splitting of C. citriodora, but lumping C, henryi in with C. maculata does not make sense to me. We get both here in SEQ, occasionally together, but for the most part they grow on different country.

Do you have any background to the move to combine the two?
Thanks, Peter.

Hey Peter,

This swap was based on Dean Nicolle's current eucalypt taxonomy, which you can see here: https://www.dn.com.au/Classification-of-the-Eucalypts.html
He currently has henryi as a synonym (see page 7 of the PDF).

As to the actual reasoning behind the synonymy, I'm unsure, I was just implementing the change

hopefully @dnicolle can weigh in and explain his reasoning for you

Hi Peter and Thomas @thebeachcomber,

I agree that there are two 'spotted gum' species is south-east Queensland (SEQ). And there is no question that the 'large-leaved' spotted gum in the Brisbane to Glenreagh area is distinct from the more widespread and common C. variegata from SEQ, it is just of question of what name to put to the large-leaved spotted gum.

One of the two 'spotted gum' species in SEQ is the widespread Corymbia variegata (syn. C. citriodora subsp. variegata), which more broadly grows from the Coffs Harbour area in NSW northwards to the Carnarvon Range in Qld, northwards of which it is geographically replaced by the lemon-scented C. citriodora.

The other of the two 'spotted gum' species in SEQ is the more restricted 'large-leaved' spotted gum from the Brisbane area, inland to Helidon, and extending southwards to the Glenreagh area in NSW, that was previously called C. henryi. These populations differ from C. variegata in their larger leaves, flower and fruits, and have different habitat preferences, but they are morphologically identical to populations of spotted gums from further south in NSW (from the Manning River Valley southwards to Bega, and also in Vic), which have always been known as C. maculata. Because the name C. maculata was published before the name C. henryi, the former name takes priority (it is the one that should be used), with the latter-named species regarded as the synonym.

Note that C. variegata was, previous to 1995, included in a broader concept of C. maculata, which may confuse things with regard to the names. More recently C. variegata was included in C. citriodora (as C. citriodora subsp. variegata), but these are now recognised at species rank.

I hope that helps explain the situation. Let me know if you have other questions.

Regards,
Dean.

Righto. Thanks to you both.

I think I may have added to my own confusion by incorrectly thinking that Corymbia citriodora subsp. variegata had changed to C. maculata.
So to summarise, in SEQ, the former C. citriodora subsp. variegata is now C. variegata, and the former C. henryi is now C. maculata, yes? 😄
Cheers, Peter.
