Coelospermum reticulatum is a species of flowering plant in the family Rubiaceae. It is native to New Guinea, the Northern Territory, and Queensland. Its natural habitat is dry rainforest and moister Eucalyptus woodland. The plant is an important source of dye for Aboriginal people. The former genus Pogonolobus with its sole species, Pogonolobus reticulatus, has been synonymised with this species.[1]
