P. C. Standley (1916b) erected Ammocodon to accommodate this primarily morning-blooming species, based on its shorter perianth, fewer stamens, and umbellate inflorescences. B. A. Fowler and B. L. Turner (1977) maintained the genus separate from Selinocarpus. A. Heimerl (1934c) included the species in Selinocarpus, as did V. Bittrich and U. Kühn (1993). R. A. Levin (2000) presented evidence to support the inclusion of this species within a Selinocarpus clade within Acleisanthes, most closely allied to A. somalensis (Chiovenda) R. A. Levin.
