Discussion | Emilia sonchifolia is a pantropical weed of Asiatic origin and should be expected as an occasional escape in the flora. D. H. Nicolson (1980) treated the eastern Asian representatives of E. sonchifolia, which have corolla lobes 1.1–1.5 mm, as E. sonchifolia var. javanica (Burman f.) Mattfeld. In the flora, plants of E. sonchifolia have corolla lobes 0.5–0.8 mm and are treated as var. sonchifolia. See Nicolson (p. 398) for discussion of nomenclatural attribution.
