Abstract

In connection with studies on the fog oasis or lomas formations at Alto Patache near Iquique, Chile, the first author encountered several Nolana species, including one new to science described here, N. patachensis J. Hepp & M. O. Dillon (Solanaceae-Nolaneae). The new species is diagnosed, described, illustrated with photographs, and compared to nearest geographic neighbors in northern Chile. To an aid in recognition, a key to Nolana species reported from region of Tarapacá is provided. Putative relationships between the various Nolana species encountered at the type locality are discussed. Conservation efforts at the type locality are highlighted, including its unique environmental conditions, biota and potential threats.
