User's notes

a group of unknown young eucalyptus. In the past years, Callitris endlicherii, Kunzea ericoides and several unknown Eucalyptuys have been planted by unknown person in this 10Ha Fair rehab site. I don't think these are a local species; they may have been planted or they may be recruits of non local Eucalyptus planted in the close by Valour Park area.

https://canberra.naturemapr.org/users/22862, the leaves to me look different to those of the eucs id-ed at the gully; all leaves including those of the smaller saplings are of ovate shape and none opposite - in the young E. aggregata of approx 1.5m height close to the gully there were still opposite leaves present.

says " juvenile leaves opposite at first but soon alternate, petiolate, ovate to elliptical or lanceolate, 4–7 cm long, 1.5–3 cm wide, margin entire or crenulate, green. Juvenile leaf shape may vary considerably...."
So we wait for flowers..

Not sure how long it will take for flowering; it took the local eucs that we planted about 8 years to the first flowers. Will someone be around to remember and check? I wonder to take samples of each of the 5 saplings as well as samples of the E. aggregata growing at the gully.

Ten years ago this issue was discussed in Eucalyptus aggregata (Black Gum) and there were flower buds at this time of year in the trees along the gully line.
So now is a good time to revisit, and I have to visit Helen Kennedy at the herbarium soon (to take in a pressed weed sample) so I could take any samples.
