Move over, Sherlock Holmes. There is a new master of disguise—and it’s a plant. Camouflage and mimicry are usually reserved for the animal realm. The hawk moth caterpillar scares away predators by resembling a snake. Myrmarachne jumping spiders imitate ants as they creep up on unsuspecting insects—fangs ready. Fewer examples of mimicry—or crypsis—are known for plants. But as in some mistletoe species in Australia, all of these imposters copy only one other species. That’s not the case with the woody vine Boquila trifoliolata, which transforms its leaves to copy a variety of host trees. Native to Chile and Argentina, B. trifoliolata is the first plant shown to imitate several hosts. It is a rare quality—known as a mimetic polymorphism—that was previously observed only in butterflies, according to this study, published today in Current Biology. When the vine climbs onto a tree’s branches, its versatile leaves (inset) can change their size, shape, color, orientation, and even the vein patterns to match the surrounding foliage (middle panel; the red arrow points to the vine, while the blue arrow indicates the host plant). If the vine crosses over to a second tree, it changes, even if the new host leaves are 10 times bigger with a contrasting shape (right panel). The deceit serves as a defense against plant-eating herbivores like weevils and leaf beetles, according the researchers. They compared the charlatan leaves hanging on branches with the leaves on vines still crawling on the forest floor in search of a tree or scaling leafless trunks. Herbivory was 33% and 100% worse for the vines on the ground and on tree trunks, respectively. It is unclear how B. trifoliolata vines discern the identity of individual trees and shape-shift accordingly. The vines could read cues hidden in odors, or chemicals secreted by trees or microbes may transport gene-activating signals between the fraud and the host, the researchers say.

Wow thats just mind blowing. To me discoveries like this realy support the idea of a plant consciousness. I know alot if folks would see that as far reaching but it just resonates as true to my life experience. Thanks for posting
