In the early 2010s, Ernesto Gianoli, a plant ecologist with the University of La Serena in Chile, realized that what appeared to be a strange-looking stem from a tree was in fact a B. trifoliata vine, the leaves of which perfectly blended in with the tree’s actual leaves. Once he saw that, he spotted the vine mimicking all sorts of plants—more than 20 species so far—by tweaking the size, shape, and color of its ...
