Origin and Habitat: Miqueliopuntia miquelii is widely distributed in the Chilean coast from the Elqui Valley north to Copiapo (regions of Coquimbo and Atacama).
Altitude range: 0 to 1,500 metres above sea level.
Habitat and Ecology: The species is confined to the deserts of northern Chile, in a wide array of soils. Guanacos disperse the segments and seeds. Miqueliopuntia miquelii, Opuntia berterii and Eulychnia acida are often the most characteristic elements of the bush in their range. Miqueliopuntia miquelii is very abundant, the population is increasing, and there are no major threats.

Common Names include:
SPANISH (Español): Tunilla, Tuna de Miguel

Leaves: Minute, 2 to 3 mm long, early deciduous.
