I am pretty sure this is Leionema. It is not Pheblium, which is covered in obvious scales. I cannot key it out to species and suspect it might be an unnamed species. Someone with a collecting permit needs to take a specimen to the herbarium while it is still flowering.

I will go back and try to find the shrub in the next week or so. It was in an area with lots of boulders so may be hard to find. The photo was taken on 22 Sept so may be past flowering by now.

Thanks Michael let me know how you go - I may be out that way searching for Little Eagles in the next two weeks

Michael M - do you agree with Betty that it may be an unnamed species?

Just adding Greg Baines comments to Michael M: "It looks like Rutaceae to me but it can be Philotheca because the stems and leaves aren’t warty. Betty has ruled out Phebalium and the petals are the wrong colour for Crowea which seems to leave Leionema. Is doesn’t look like any of the Leionema in NSW flora so maybe it is undescribed?"

Dave Albrecht of the CSIRO Herbarium identified this as Box Micrantheum, which is a new one for me. The atlas of Living Australia has about 40 records of this plant in the Act, where it is near its inland limit. There is a 1955 collection by Moore from about the same location at this record

If you look carefully at the leaves in photo 1, you can see that the leaves are in threes, typical of this species. Plantnet states that male flowers have 6 or 9 segments. The flowers in the photos have 6 segments, three large and 3 small, There are no female flowers in the photos. I can see these details now, but did not pick them up on the first go.
