A. albispathus is most similar to A longituberosus (Engl.) Engl. & Gehrm. They share the general inflorescence morphology, the short, hairlike papillae in the spathe-base, the large, helmet-shaped connective with lateral pores, the anise-like scent and elongate tuber. However, the leaf-blade of A. albispathus is much less strongly divided and the leaflets are much larger, the petiole is much sturdier and the tuber is much shorter and branched.
