User's notes

Growing near the edge of a swampy drainage line. The flower colour and some leaf characteristics seem to place this close to Stylidium montanum if several papers on the Victorian flora are followed.

If you now have your collecting permit, you should press this and give it to the Australian National Herbarium. Dave Mallinson is the contact. It looks like another sighting that does not easily fit into the three species in the Stylidium paper.

Perhaps we need a separate listing for a Stylidium graminifolium complex for specimens such as this. I will see what I can do about making a collection.

Looks fitting well into Stylidium montanum to me, according to the diagnostic features available in the further studying of the original sources I am doing at the moment.
Please refer to more information i have added to the species pages, including here : Stylidium montanum

The plant went to Dave Albrecht at the herbarium, he showed it to Juliet Wege visiting from Western Australia who was/is working on a Stylidium monograph. She acknowledges that there are still problems in the S.graminifolium complex and that it needs quite a lot more work. Having said that she was happy that this specimen fits S.graminifolium in the strict sense. We were concerned about the flower colour being too dark, but she says flower colour is pretty irrelevant in that group. Since the plant is with the herbarium and I sent the jpg images in as well I thought I would just wait to see what in time eventuated. I don't travel much beyond the ACT borders these days and even within the ACT borders I give the severely burnt areas a miss for at least a decade. I have no wish to risk introducing pathogens and weeds into severely disturbed ecosystems simply for a few photos. Such an approach does limit my understanding of species variability.

Well that's wonderful information to learn more from – I read Juliet Wege's wonderful published works .
I really appreciate David Albrecht's work – he was one of my mentors in the occasional mid. 1980s–early 1990s times when i was in the MEL herbarium and he was there too until he moved on .
I really appreciate Juliet Wege's work .

Thanks @KenT – please refer for more information to the publications' quotations by Juliet Wege (2017) and by Raulings, E. J. and Pauline Y. Ladiges (2001) which i previously shared in the species pages, also here : Stylidium graminifolium
.

I had already looked closely at these three of your photographs – now i'm looking even more closely,
at the scape hairs below the lowest flower (though the scape bottom above the leaves seems glabrous),
and at the undersides of the leaves, including their undersides' midribs whether prominent or not .

So as to learn more and working to see more of the diagnostic features which Juliet Wege and David Albrecht probably checked in the herbarium specimen of this plant which you lodged .

Hence, i can now see scape hairs below the lowest flower, which i did not see looking closely last time, but I was not looking as much so closely at that scape part . Stylidium montanum has one of the diagnostic features of glabrous scapes below the bottom flower –according to the botanical literature .
Yet still haven't found any published botanical literature reading particularly clarifying of where the threshold is in the degree of prominence of the leaves' undersides' midribs .

The date and location on this site are correct there seems to have been a transcription error in some of what has made it into the AVH

Okay !
Here is the specimen in the Au Nat. herbarium specimens database directly : https://www.canbr.gov.au/cgi-bin/herb-detail?FORMAT=TABLE&0060=Thomas%25&1040=Stylidium&4020=ACT
