Occurrence

Emilia coccinea is native to tropical Africa . It grows there in forest clearings and along roadsides. In Mexico, Central and South America, on islands in the Caribbean, on Mauritius, Hawaii, Madeira and New Caledonia it is a neophyte . In the mountains, Emilia coccinea can be found up to an altitude of 4000 meters.

Taxonomy

The first publication took place in 1802 under the name ( Basionym ) Cacalia coccinea by John Sims . The new combination to Emilia coccinea (Sims) G.Don was published by George Don . The generic name Emilia was probably created in honor of the French natural scientist Émilie du Châtelet, b. Gabrielle Émilie Le Tonnelier de Breteuil, Marquise du Châtelet-Laumont (1706–1749). The accepted name might be Emilia fosbergii Nicolson.
