brown wooden signage on green plants

While many culturally important plants, such as sagebrush and pinyon, are common across the landscape, at least 31 species, including the Four Corners potato (Solanum jamseii), are common at the sites, yet rare elsewhere, according to the study, posted Monday by the Proceedings of the National Academy of Science. Other such plants included goosefoot, wolfberry and sumac, which produce edible grains or berries.
