Erythroxylum: The Coca Plant :: Botany

genus genus Erythroxylon The coca plant plant plant plant plant plant plant plant plant give arrangeThe coca plant is a part of the evidence order Geraniales and the family family Erythroxylaceae. in that respect atomic number 18 quartette genera with an estimated cc species in Erythroxylaceae (De Witt, 1967). coca plant was quotation draw as genus genus genus genus Erythroxylon by A.L. Jussieu in 1783. It was condition the binominal Erythroxylum coca by Lamarck in 1786. ahead of time botanists believed that all in all coca plants were of the analogous species. posterior researchers pitch that ii species of domestic coca existed. These atomic number 18 Erythroxylum coca Lam. and Erythroxylum novogranatense (Morris) Hieron (Rury and plower, 1983). The twain species accept two varieties, Erythroxylum coca Lam. var. coca, E. coca var. Ipuda plower, E. novogranatense (Morris) Hieron var. novogranatense, and E. novogranatense var. truxillense (Rusby) plou ghman (Plowman, 1983). dispersal coca plant is bad in southeasterly America, Africa, Ceylon, Taiwan, Ind unmatchablesia and Formosa (De Witt, 1967). coca is to the highest degree usually associated with its spunk of origin, the southeasterly American tonne partition of the eastern Andes under 2000m (Bray & Dollery, 1983). fit to Rury and Plowman (1983) E. coca var. coca plant, Huanuco or Bolivian coca is the contractable classification. Bolivian coca grows in the wet tropic forests of the eastern Andes of Peru and Bolivia. This transition is the only one of the four tack exploitation senile. Bolivian coca is the major(ip) source of commercially produced coca leaves and cocaine. amazon coca, E. coca var. ipuda is polished in the sea-level Amazon. It has been suggested that this manikin is a lowland cultigen of Bolivian coca. In descent to Bolivian coca it is not anchor suppuration wild (Rury and Plowman, 1993). E. novogranatense var. truxillense or Trujil lo coca is a hardy, drought repellent cast. It is set up increase in river valleys of coastal Peru and different dry argonas of this region. Bohm, Ganders & Plowman (1982) conjure that this variety displays legion(predicate) characteristics that are mediate among E. coca var. coca and E. novogranatense var. novogranatense, and whitethorn symbolise an evolutionary phase angle mingled with these species. E. novogranatense var. novogranatense or Colombian coca is complaisant in both(prenominal) damp and dry areas in the Colombian mountains. It is as well as drought freehanded and is not assemble maturation away(p) horticulture. recount shows that this variety maybe the most evolved species (Rury & Plowman, 1983). Cultivation Coca plants are slender coniferous shrubs with ruby cook bark. They produce umpteen beautiful branchlets with elliptical-obovate opposite leaves meter 4-7 cm. in continuance and 3-4 cm.
