Prostrate Flowering Pea, Red and Yellow blooms about 2-3cm, leaves ovate, up to 1.5cm long and about 1cm wide, growing in dry litter below scribbly and Yellow gums, Grassy Woodland, along Clancy's track. Each 'bush' is sprawling, variable in surface area from 0.5 to 3sq m. Occurs only at one relatively small site along Clancy's track (here). Inconspicuous, unless flowering.
Max I think Bossiaea is correct; perhaps B buxifolia. We have one record of B buxifolia and a couple of B prostrata for Mt Majura. If you can find it again please collect a sample; I think the leaves of the 2 species can be distinguished.
