This is the best known and most widely distributed species of the genus, much collected in the West Indies and in Central America as well as in eastern South America. It is the common Myrciaria from Venezuela through the Guianas to eastern Brazil. Its range extends inland along the Orinoco and its tributaries, but on the upper Orinoco it seems mostly to be replaced by M . dubia. Apparently it does not occur on the middle and lower Amazon in Brazil, where M . dubia is common, but it is now reported for the first time from Peru.

The name Eugenia floribunda has often been attributed to West, but he pubhshed the name as a nomen nudum, without botanical description, stating merely that the fruit are aromatic, red or yehow, used by the Negroes in making rum (West, H. Bidr. Ste. Croix 290. 1793). Willdenow supplied a description, attributing the name to West but giving the page as 216. The plant in the Wihdenow herbarium may be taken as the type (No. 9524!, labelled "Eugenia floribunda," "in Insula St. Crucis " and "Vahl"). It is an ample flowering specimen of a nearly glabrous plant. P E R U . Loreto: San Antonio, alto Rio Itaya, elev 145 m, 7 Oct 1929 (fr), Williams 3469 (F).
