Along with two native species of lettuce on the Beach, there is an alien one, considered weedy even in its native Europe. This curious plant is called 'compass lettuce,' as its leaves are always oriented in a vertical plane and pointing in the north-south direction. This is an adaptation providing for cooling leaves, so the plant is not overheated in open habitats like this one. — Photo Alexey Zinovjev [41.96593 -70.64314] [acme mapper]
