Phymaspermum Less. (I.v.) was originally described with a single species indicated: "Ph. junceum *= Osteospermum junceum Thunb. fl. cap. p. 714", but has since been expanded to include ca. 18 species, all endemic to southern Africa.

Bot. 5: 535-538. 1985; Germishuizen & al., Checklist S. African PL: 243. 2006) and distinctfrom Osteospermum junceum P.J. Bergius (Descr. PI. Cap.: 334.1767), an accepted species of Osteospermum L. (Sp. PI.: 923. 1753). Lessing's inclusion of O. junceum Thunb. as a synonym, however, effectively links P. junceum via Thun-berg (Fl. Cap., ed. 2:
