An erect plant about a foot high with thin dichotomous branches. The flowers were very small, about 5 mm wide with bright yellow petals. Leaves were small, lanceolate and some had indented margins.
Spotted growing amongst other vegetation like dandelion, sorrel and grass by a walking track, in a national park. It was difficult to see this plant separate to the others growing in the area but the bright yellow flowers looked like little stars suspended amongst tall grass.
Paropsisterna semifumata. This small beetle is a riparian species and feeds only on white Callistemon spp.? growing in creeks and rivers along the eastern coast of Australia up to Brisbane. I've seen it both times that I've looked at this reserve but its probably common enough along Jacksons Creek wherever you find Callistemon. Semi + fumata translates in Latin to half + smokey.
