Enations are scaly leaflike structures, differing from leaves in their lack of vascular tissue. They are created by some leaf diseases{{citation needed|date=February 2022}} 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.{{cite web|url=https://www.britannica.com/plant/lower-vascular-plant|title=Lower vascular plant - botany|author=|date=|website=Encyclopedia Britannica|accessdate=8 May 2019}}
