DunT, GGr, Wim. Also SA. Confined in Victoria to the Grampians where found in dry rocky soils.

This species has been confused with Gonocarpus teucrioides but can be distinguished by its less robust habit, thinner subcaudate leaves with coarser teeth, reddish-brown toothed bracteoles and the flowers all alternate. Hybrids with Gonocarpus elatus have been observed.
