Sarcomphalus mistol

About

Sarcomphalus mistol or mistol is a species of spiniferous shrub or tree of the family Rhamnaceae. It is native to Peru, Bolivia, Paraguay, and northern Argentina in South America, and very abundant in parts of the Gran Chaco of northern Argentina and Paraguay. The word "mistol" derives from colonial era Spanish, from the word "mixture" (mezcla) since it was believed that mistol was a hybrid between species of genus Schinopsis because of the likely color of its wood to Spaniard colonists' perception.
