Yes. Interesting. I notice here: • glandular hairs below the lowest flower on the scape, a little bit fine scape narrow diameter . • not so many flowers at least yet compared to usual in: Stylidium graminifolium and Stylidium armeria subsp. armeria . • the leaves have pale colour, more upright (not horizontal nor a rosette), • the leaves' serrations as said above and notice the serrations do not continue all the way to the leaves bases along the margins of these leaves – more like averaging 3/4s or 4/5s the way down showing here in some of the leaves in photograph 3 .
Hence in currently available published names, IMHO seems partly closer to *Stylidium montanum* and yet seems to have some genes' introgression from *Stylidium graminifolium* (in the strict narrow sense) .
Please see more information in the publications in the species pages, including links to, citations of and summary part quotations of, most relevant scholarly published botanical articles, here : Stylidium montanum .
Also how about callling this Stylidium armeria according to Raulings and Ladiges (2001) – levity for a moment for all reading here (not serious) .
Seriously in professional botany ways, I temporarily label this: " Stylidium cf. montanum et cf. graminifolium? (Crookwell district) " according to taxa concepts in Elisa Raulings and Pauline Y. Ladiges (2001) and subsequent clarifications by Juliet Wege (2009, 2017) – see here : Stylidium montanum .
