Bull. Sci. Soc. Philom. Paris1817: 68. 1817
Introduced; chiefly Old World tropics, some weedy in New World tropics.
Species 50–100 (2 in the flora).
D. H. Nicolson (1980) pointed out that Emilia is taxonomically complicated with poorly defined, weedy species and an involved nomenclatural history. Emilia coccinea (Sims) G. Don is occasionally cultivated as an ornamental; it is not known to escape and persist in the flora. It keys here to E. fosbergii, from which it differs in having involucres 6–9 mm (lengths typically 1.5 times diameters). In cultivation, it has bright red to dark orange corollas. Nicolson provided drawings that illustrate the distinctions.
|1||Leaves mostly in proximal 1/2, usually petiolate, blades ovate to obovate or oblanceolate, mostly 5–12 × 1.5–4.5 cm, margins often deeply lobed to lyrate-pinnatifid; involucres mostly urceolate to campanulate, relatively slender, lengths mostly 3–4 times diams.; florets 15–30[–40]||Emilia sonchifolia|
|1||Leaves ± equally distributed, sessile and auriculate to winged-petiolate and clasping, blades oblanceolate to pandurate, mostly 5–10 × 3–5 cm, margins entire, toothed, or weakly lobed; involucres mostly campanulate to cylindric, relatively thick, lengths 1.5–2(–3) times diams.; florets usually 50–60+||Emilia fosbergii|
