Again, tricky. Could be B. gregsonii, B ambiguum, or (less likely) B. minus or B watsii. Fertile fronds would assist in ID

Tricky, given the location . Could be B maximum. Doesn't look like B. cartilagineum, but just possibly could be B minus. Might not be in the ACT++ list

Blechnum sp.

I reckon *Psilotum nudum* too,
yet systematically following the botanical keys i read at the time says *Psilotum nudum* usually does not have as flattened stems as this sighting's and pointing somewhat towards *P. complanatum* genes (one of the motivations for sharing this sighting here, as i have other clearly *Psilotum nudum* sightings not in here) .

Introgressions happen a lot in plants especially in edge areas or disturbed areas .

At this location this small area of street tree, is surrounded by largely treeless suburbia, so in evolutionary time scale terms quite unusual habitat for this species and we anticipate unusual interactions .

Clearly detecting introgression and evidencing it sufficiently to publish is a whole 'nother level of work (of course).

It looks more like what I know of P.nudum to me just at a glance. Were you unsure or?
