2022, the year that was

The Doc’s main theme for images in 2022 was barks and then flowers as Spring arrived. Over 6,000 images were posted to the Atlas of Living Australia in 2022. Consulting work prevented any travel, even after many of the lock downs stopped.

The first trip for 2023 is booked, Foray with Friends at Dorrigo on the mid north Coast of NSW. The theme will be fungi’s and slime molds. There is some consulting work to finish at the end of January then The Doc has more flexibility, once the final work on the Patrol is finished in mid-January.

Eucalyptus kessellii subsp kessellii – bark

It was harder to find the common name for this tree than the previous one. Mt Annan Botanic Gardens called it Eucalyptus inversa, The Doc finally found other names including Eucalyptus inversa, Eucalyptus irritans, Eucalyptus israelitica, Eucalyptus kessellii subsp kessellii, Eucalyptus goniantha or the Jerdacuttup Mallee. The Doc chose the Brooker taxon of Eucalyptus kessellii subsp kessellii.

Bark rough, very hard and grey-brown to blackish over lower part of trunk, or smooth throughout on smaller mallees, smooth bark grey-brown and pale brown to pink-orange. EUCLID 4th Ed https://apps.lucidcentral.org/euclid/text/entities/eucalyptus_kessellii_subsp._kessellii.htm

Corymbia hendersonii – bark

Mt Annan Botanic Gardens referred to this as Corymbia cafie, a little used name. It took The Doc some time to find the more commonly used name of Corymbia hendersonii or Henderson’s bloodwood.

Bark rough over trunk and branches to ca 2 cm diameter, coarsely tessellated, grey to dark brown. EUCLID 4th ed https://apps.lucidcentral.org/euclid/text/entities/corymbia_hendersonii.htm?zoom_highlight=Corymbia+hendersonii

Syncarpia hillii – bark

Bark of the Fraser Island Turpentine, which is heavily textured with deep furrows and hills on the trunk. This tree was 10.51 metres high. Bark varies greatly on each specimen.

Wollemia nobilis – bark

Arguably the rarest tree in the world, at least in the wild, the Wollemi Pine. There is a handful of specimens still alive, all genetically identical. Zero genetic variation in the population means they all come from the same tree.

You can buy them in a nursery, because after its discovery in 1996 the NSW Botanic Gardens set about growing it in quantity through nurseries, to reduce the risk of people looking for the few trees in the wild. It was only previously known from the fossil record.

This is the bark on an immature tree 3.93 metres high, from the NSW Botanic Gardens.
