According to the Plantnet key, the key difference between Callitris muelleri and the more widespread Callitris endlicheri (or any other Callitris in the area covered by the Budawang Nature Map) is that the leaves are are mostly more than 5 mm long, and the leaves of the other species usually 2-4 mm long. Please comment.

'BettyDonWood': I've uploaded 2 more images with ruler for scale. Most seem to be greater than 5mm long. I have an image from another nearby tree with possible flower buds/pods if needed.
Cheers Ry

Hi Ry What you are looking at are branchlets, not leaves. The actual leaves are the tiny swellings that tightly cling to the branchlets. In addition, the cone in the photo does not have the small point near the tips of the woody cone scales when it is right way up. Betty
I think someone should have a look at this in the hand. I have tried keying it out and decided that it is not Callitris muelleri and probably not rhomboidea.

Sorry. I live in Canberra and have difficulty walking 100 metres. It will have to be one of the local moderators.

Hi, I've uploaded photos of the 'leaves'. Most are more than 5mm long.
Does this confirm Callitris muelleri?
   14 Aug 2019
What you are measuring appears to be immature male cones. The leaves are green, tiny, and mostly pressed tightly to the branchlets. The only Callitris in south eastern NSW that has single male cones is Callitris glaucophylla. However, it usually sheds its mature cones shortly after the seeds are shed. Also there are no records for it this far east south of Sydney.

Ok, thank you Betty. Let me know if there are any other specific photos that would help ID.
cheers,

Ry, I am sorry about confusing you about the leaves. I had forgotten that they are pressed closely to the stems.
The characters in the Plantnet key that distinguish muelleri from all other species of Callitris in the area are: stems more or less triangular with rounded-obtuse angles to +/- three-lobed in cross-section (photo difficult but it is easy to feel - a comment will be fine); cone scales with a distinct dorsal (on the back) protuberance or apical (at the tip) point. Again, a comment will do, though a photo showing these characters eg a side-on and a head-on photo of the mature cone, would be good.
I have just read Joy Thompson’s paper in Telopea that created the name Callitris glaucophylla. In the key in that paper, she stated that what separates the Callitris glaucophylla group from all other species of Callitris in Australia is that the cones are solitary, the cone scales separating almost to the base in mature cones. That appears to be the case in your photo, but is much easier to see in the hand. Again, a comment is fine.
