XVI International Botanical Congess
This study was conducted in the Andean Southwest of Colombia including some life zones of the West, and central mountains. The altitudinal range begins at 650 m, tropical dry forest (b-ST) and 3100 m (paramune zone). Viscaceae represents the widest distribution in life zones sampled. Loranthaceae were localized between 1650 m premountain humid forest (bh-PM) and 3100 m. Cuscutaceae was collected at 3100. Viscaceae and Loranthaceae were distributed in premountain wet forest (bmh-PM) as well. Hemiparasite plants colonize primary and secondary forests and agro-eco-systems, preferentially in woody plants. The economical importance of some genus is related to infections in fruit trees and crops.
