In Mark Clements considered opinion we only have C. montana in the ACT. Without definitive DNA analysis to the contra it is difficult to split what is possibly just natural variation. C. fitzgeraldi has been previously considered and been subsequently been abandoned.
That’s a fair call. I am still very sceptical about the differences (as you know) but thought I thought it fit for fitzgeraldii based on our previous discussions. If we are using DNA to split, then I will confirm as C. montana.
