One of the quite wonderful Lycopods (as they used to get called before much more work on their classification happened which re-arranged many spp. in different genera. These do remain still in the botanical family: Lycopodiaceae. ).

I need to look into the botanical key (again), and check the latest botanical name .

_Selaginella uliginosa_ has less tall, less clustered branches, with not so densely packed leaves..

And does not identify to _Pseudolycopodium densum_ (synonym: _Lycopodium deuterodensum_ ) .

Austrolycopodium fastigiatum

one of the two Azolla: but can't tell which without a close-up.

Azolla sp.

Many years ago Max Gray in CSIRO told me that A. trichomanes almost always was associated with limestone. So I went out to the Cotter Cave, a local limestone outcrop, and sure enough, the area was 'infested" with the fern. Might be interesting for someone to check if it is still growing there (I no longer live in Canberra). The 2003 bushfires might have had some effect on it.

Asplenium trichomanes
