GPSed. Was very windy making it difficult to get good pics. Flowers ~ 25mm across? Plant heights say 40-50cm. Basal leaves very hairy. Seems to be the dominant Wahlenbergia in this part of the site. Guesstimate at least 1000 plants, within say 60m+ radius of GPS point, in this part of the "south" paddock. I note free lobes of the flower look like they are less than 4 times as long as the tube as opposed to the characteristic >4x length - so my other guess would be W. graniticola.
I'm pretty happy with W. planiflora, it matches that species well to me, this doesn't look right for W. graniticola to me either, I don't get the vibe that this is the right habitat for it either. Wait to see what Ciaran has to say.
Thanks guys. Good to know that it's W. stricta and to have another Wahlenbergia species added to the list for this site. Note the style/stigma appears to protrude just above the flower tube (see 2nd & 3rd pics) which from LUCID factsheet (https://apps.lucidcentral.org/plants_se_nsw/text/entities/wahlenbergia_stricta.htm) is more common with subsp. alterna?
