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.

Emilia fosbergii is a tropical Asian weed that has become established in the flora; it may be expected elsewhere as an occasional escape. It is the more frequently collected Emilia in the flora. Names misapplied to plants of E. fosbergii include E. javanica (Burman f.) C. B. Robinson and E. sagittata Willdenow. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
