Batis argillicola P. Royen occurs along the coasts of southern New Guinea and northern Australia. It differs from B. maritima in being monoecious and having solitary flowers, shorter leaves, tepals of staminate flowers each with one vascular bundle and a tapered base, and winged filaments. Wood anatomy and habit of the two species are similar. There was an earlier dubious chromosome count of x = 9.
