最初是從, Bolivia, Peru
Known from the Andes in Bolivia (La Paz, Cochabamba, Santa Cruz and Chuquisaca) and Southeastern Andes of Peru (regions Cuzco and Puno), at 1285-2800 m, on slopes in patches of cloud, semi-deciduous, or deciduous forest (in the Yungas humid forest, the deciduous mountain Chaco forest, and the Tucumano-Boliviano forest). It is often observed along with Parajubea in cloud forests disturbed by grazing, or in transitional forests between cloud forest and dry forests, mixed with Podocarpus sp., above limits of subtropical deciduous dry forests with Dictyocaryum lamarckianum, but never in dry forest. It can form populations of over several hundred trees along ridgetops, but is mostly seen as scattered sub-canopy individuals. In Peru, it is conserved in cultivated plots and favored in shade coffee plantations, where it can be more abundant than in natural conditions. Nevertheless, most of the natural habitat is being rapidly converted to pastures and cultivation.
