It grows as a prostrate aromatic annual, with hairy stems that branch from its base. Leaves are oval in shape, about fifteen millimetres long. Flowers occur in dense clusters located in the axils.[1]
It was first published in 1922 by John McConnell Black, as a variety of C. carinatum,[2] and promoted to species rank by him in 1934. Two forms have been published, although these are only recognised in South Australia and Western Australia; they are C. melanocarpum f. melanocarpum and C. melanocarpum f. leucocarpum.[3] In 2008, Sergei L. Mosyakin & Steven E. Clemants grouped this taxon in genus Dysphania. [4]
It occurs in arid and semi-arid areas of Australia, usually in well-drained soils.[1]
