User's notes
Many single flower stems located in a stock excluded pasture. Have emerged on drought affected pastures that have recently received 260+mm. Stalks all emerged and flowered at roughly the same time after the first significant downpour - long lived flower stalks with buds gradually flowering up the stem, no new examples following more recent rain.
Leaves at base not hairy (?)
[This type of trigger plant encountered (not flowering) in first Sth Talaganda survey in the mid 1980s, along road reserves, but not sighted for some time.]

Stylidium graminifolium generally grows on sand/sandstone. It has white to pink or mauve flowers, and leaves 1-3 mm wide, with the midrib clearly visible on the lower suface. The last character is hard to photograph and a comment to say so is best unless you have a good camera and some luck.
Stylidium armeria subsp. armeria lives on other types of soil, has bright pink to magenta flowers, and leaves 3-15 mm wide, the midrib not obvious.

Thanks BettyDonWood, i have added some additional pictures isolating one of about 80 plants observed. The b&w scale on the field sheet in the 2nd and 3rd pics are in cm, so leaf width was 2-3mm. The 5th picture is a close up of top and back of leaves - the front leaf in the picture is the back of the leaf. It seems to have a midrib - at this magnification it also shows small hairs/spines along the leading edges of the leaf.
Thanks for your patience :)
