In the first photograph no appearance of hairs along the scape below the lowest flower (–though not fully in the focus view-field ) – :
If checked in the field, together with measuring the scape diameter and checking the leaves match then consider as a candidate : Stylidium montanum.
Or if the leaves don't match, and hairs do grow along the scape below the lowest flower, then the more likely candidate : Stylidium graminifolium.
Genes of all three related grassy trigger plants species : • Stylidium graminifolium <–> Stylidium montanum, • Stylidium graminifolium <–> Stylidium armeria have partly introgressed in populations' habitats' ecotones according to published information by Raulings and Ladiges (2001) and Wege (2017) – but in published evidences i read : not introgession between, genetically isolated species, co-occuring : Stylidium montanum |–| Stylidium armeria .
