SummaryContrary to views that cassava (Manihot esculenta) is only known in cultivation an argument is made that wild accessions of the species grow over much of the American neotropics, in Brazil, Bolivia, Peru, Venezuela, Guyana, and Surinam. Three subspecies are recognized. M. esculenta subsp. esculenta is the domesticate and includes all cultivars known in cultivation. The wild M. esculenta subsp. peruviana occurs in eastern Peru and western Brazil. The wild M. esculenta subsp. flabellifolia shows a wider distribution and ranges from the central Brazilian state of Goiás northward to Venezuelan Amazonia. The large area of distribution of the two wild subspecies makes it difficult to assign a place of initial domestication.

- Screening of Starch Quality Traits in Cassava (Manihot esculenta Crantz) (2009, background): “Among the materials evaluated there were 12 genotypes representing four different wild Manihot species (M. chlorosticta, M. carthaginensis, M. esc. flabellifolia and M. filamentosa).”
- Domestication and Diversity in Manioc (Manihot esculenta Crantz ssp. esculenta, Euphorbiaceae) (2008, background): “As delimited by Allem (1994), this taxon is distributed on an arc partly encircling the Amazon basin, from eastern Bolivia and Peru eastward to northeastern Brazil, northward to the Guianas, and then westward to Venezuela.”
- Molecular differentiation, diversity, and folk classification of “sweet” and “bitter” cassava (Manihot esculenta) in Caiçara and Caboclo management systems (Brazil) (2007, background): “esculenta) was domesticated at the South America lowlands 7,000 years ago at least, and it has been still considered as one of the main crops for the Amerindians and a traditional species in Brazil ( Allem 1994; Olsen and Schall 1999).”
- Origin and domestication of native Amazonian crops. (2010, background): “Allem also speculated that manioc was domesticated somewhere on the Central Brazilian Plateau, the main center of diversity in South America, where 53 Manihot species occur.”
