Acomastylis elata var. elata is similar to Coluria longifolia, but differs in having a persistent style; the latter species has a filiform style evenly thickened throughout its length and deciduous in fruit. The indumemtum of the achene is variable, even in one individual, and var. leiocarpa cannot be distinguished on the basis of having a glabrous or sparsely pilose achene.
