Dawson White - The Complex Evolutionary History of Coca
19:27 Lamarck described Erythroxylum coca in 1786:
See Encyclopédie méthodique. Botanique:44:26 There seems to be another possible progenitor of the cultivated species, Erythroxylum cataractarum see Wade Davis' report of collecting a specimen of this "coca monte" from an 8m tall tree in 1976 at 1:14:25. See Crime Pays But Botany Doesn't - Erythroxylum gracilipes:The Mother of Coca, but there were possibly two (or three: 53:47) different lines of domesticated coca, one in the North (Trujillo and Colombia) and the other in the South (Yungas). He hasn't mentioned the possibility of cross-pollination between different cultivars subsequently brought together. At 1:07:00 he talks about the modern hybrids created for Cocaine production.
