User's notes

The parent tree of these King William Pines was planted here about 40 years ago, and its long-dead trunk & limbs are still standing (photo 1, far RHS). Photo 1 shows the oldest specimen now growing, as well as a younger one leaning into it on the RHS of the photo. Photo 2 focuses on the canopy, and photo 3 on part of the very upper trunk and seed cones. This tree has both rough furrowed and dark bark on its trunk and oldest branches (photo 4), but smooth, lighter coloured and partly mottled bark on younger specimens’ trunks (photo 3). Photo 4 shows the rough barked mid trunk section of the oldest tree with younger smoother and lighter coloured branches emanating from it. Photo 5 is of a much younger specimen in an attempt to get some clarity on the leaves. All are growing in poor sandy soil and get full sun most of the day in Summer.

The foliage you've shown here does not match that of a King Billy Pine - it looks more like a Callitris. Are you sure the photos are all of the same species? If so, these are not King Billy Pines (Arthrotaxis selaginoides).

Thanks for that info & suggestion @CSteele, I'll check it out more closely, when I can get back there, with Callitris & consistency between them in mind. Anything I should particularly focus on that might be more useful?

In the fifth photograph we can see the leaves quite well enough for partial identification,
according to the Flora of NSW online PlantNet botanical key of:

Note, these fresh leaves shown in photograph 5 appear acutely angled in would be cross section and
the keels shown on each leaves' dorsal surface appear acutely keeled.

Please clarify whether or not,
these fresh leaves really do have cross sections acutely angled ?
[and]
the keels shown on each leaves' dorsal surface have acute keels ?

• _Callitris baileyi_ – i suggest based on other features shown here such as the white (glaucous) smaller branches.
[or]
• does not really look like _Callitris macleayana_ and the cones do not fit.
.

The cones, how long ?
• < 15mm ?
[or]
• > 15 mm ?

Thanks for this info, & questions to follow-up @JasonPStewartNMsnc2016. As with @Csteele4, I will get back to you once I get back to the site. Hopefully this week, didn't make it when I last thought I would. Cheers, MazzV
