Four taxa of the plant genus Erythroxylum; Erythroxylum coca var. coca (Ecc), Erythroxylum coca var. ipadu (Eci), Erythroxylum novogranatense var. novogranatense (Enn) and Erythroxylum novogranatense var. truxillense (Ent) are cultivated primarily for the illicit extraction and processing of cocaine. Despite their economic and medical importance, the evolutionary history of these species remains unknown in a modern phylogenetic framework. The aims of this study were to: (a) investigate the… 

The Origins of Coca: Museum Genomics Reveals Multiple Independent Domestications from Progenitor Erythroxylum gracilipes

This chronology of coca domestication reveals different Holocene peoples in South America were able to independently transform the same natural resource to serve their needs; in this case, a workaday stimulant.

Three new species in Brazilian Erythroxylum (Erythroxylaceae)

Three new species of Erythroxylum (Erythyroxylaceae) from the Atlantic Forest of Northeastern Brazil are described and illustrated and provisionally considered as Critically Endangered (CR) or Data Deficient (DD).

Erythroxylum in Focus: An Interdisciplinary Review of an Overlooked Genus

The genus Erythroxylum contains species used by indigenous people of South America long before the domestication of plants and contain untapped resources for the benefit of mankind in the form of foods, pharmaceuticals, phytotherapeutic products, and other high-value plant-derived metabolites.

Phylogenetic inference in section Archerythroxylum informs taxonomy, biogeography, and the domestication of coca (Erythroxylum species).

It is shown that neotropical Erythroxylum are monophyletic within the paleotropical lineages, yet Archerythroxylum and all of the other taxonomic sections from which the authors sampled multiple species lack monophyly.

Genome Size and Descriptors of Leaf Morphology as Indicators of Hybridization in Colombian cultigens of coca Erythroxylum spp

The current hypothesis is that hybrids must show intermediate morphologies and genome sizes of the parental varieties, and that these variables could be correlated, and genome size and leaf morphology could be used as indicators of hybridization in cultivated coca populations.

Ancient Use of Coca Leaves in the Peruvian Central Highlands

Coca, of the genus Erythroxylum, is a stimulant and painkiller that played key roles within the Inka state. As reported by the early Spanish chroniclers, coca was the most important plant offering

Coca leaves in the context of the central Andean Wari state

Introduction The central Andean Middle Horizon (ca. 550 – 1100 CE) was a period during which the Wari State emerged in the Peruvian central highland valley of Ayacucho and established political and

Erythroxylum en el foco: revisión interdisciplinaria de un género ignorado (Erythroxylum in Focus: An Interdisciplinary Review of an Overlooked Genus)

El genero Erythroxylum contiene especies utilizadas por los pueblos indigenas de America del Sur desde antes de la domesticacion de las plantas. Dos especies, la E. coca y E. novogranatense, han sido



Biosystematics and Evolution of Cultivated Coca (Erythroxylaceae)

Evidence from artificial hybridizations, leaf flavonoid chemistry, and breeding system studies was used to clarify the taxonomic and evolutionary relationships of these plants, and evidence suggests that E. truxillense is intermediate between E. coca and E. novogranatense but it is not a hybrid between them.

Inter- and intra-specific variation among five Erythroxylum taxa assessed by AFLP.

There is a heterogeneous genetic structure among the cultivated Erythroxylum taxa where E. coca and E. novogranatense are two independent species and a founder effect may have occurred as E. ipadu moved from the eastern Andes in Peru and Bolivia into the lowland Amazonian basin.
