Scaevola amblyanthera was first formally described in 1859 by Ferdinand von Mueller in his Fragmenta Phytographiae Australiae, from specimens collected near the Nicholson River in the Gulf of Carpentaria. The specific epithet means 'a blunt anther'.In 1992, Roger Carolin described two varieties of S. amblyanthera in the Flora of Australia, and the names are accepted by the Australian Plant Census.Scaevola amblyanthera F.Muell. var. amblyanthera has no, or very sparse glandular hairs, and curled or tangled simple hairs, often so dense as to almost hide the leaf surface.Scaevola amblyanthera var. centralis Carolin has many glandular hairs and simple leaves not usually dense or tangled, the leaf surface visible beneath the hairs.
