Enations are scaly leaflike structures, differing from leaves in their lack of vascular tissue. They are created by some leaf diseases[citation needed] and occur normally on Psilotum. Enations are also found on some early plants such as Rhynia, where they are hypothesized to have aided in photosynthesis.[1]
