Erythroxylum

Erythroxylum ("Erythroxylon") is a genus of tropical flowering plants in the family Erythroxylaceae. Many of the approximately 200 species contain the drug cocaine; "Erythroxylum coca", a native of South America, is the main commercial source of cocaine and of the mild stimulant coca tea. Another species, "Erythroxylum vaccinifolium" (also known as catuaba) is used as an aphrodisiac in Brazilian drinks and herbal medicine.
"Erythroxylum" species are food sources for the larvae of some butterflies and moths, including several "Morpho" species and "Dalcera abrasa", which has been recorded on "E. deciduum", and the species of "Agrias".
