Almost finished flowering. Where the trunk had been damaged at ground level, there were some shoots. Photos show leaf edge, which is a feature distinguishing Manchurian Pear from Callery Pear. These trees probably planted in the 1960s.
@Mike I went to this location because it is listed in https://www.woodcraftguild.org.au/wp-content/uploads/2012/10/ACT-STREET-TREES.pdf which covers plantings up to early 2001, and it is close by! The leaves are not fully expanded yet, but the measurements of the biggest ones are OK and the shape is also right. The leaf lamina has no hairs, front or back. The only "hairs" are the bristles on the edge serrations. There are 203 streets with plantings of this species, sure to be one not too far away. Only 21 streets with P. calleryana, mostly Red Spire, and only one Bradford, at Anzac Park, Reid. I wonder if it is still there?
@Mike I've had a look at several of the Callery pear trees near the reserve in north Watson, and they do have a few hairs along the leaf edges, but not at the tip - and not nearly as many as in this Manchurian Pear. But it is not an all or nothing situation, unfortunately. So the only other thing is the persistence of the calyx on the ripe fruit in Manchurian.
