Enation
Scaly leaflike structures, differing from leaves in their lack of vascular tissue
From Wikipedia, the free encyclopedia
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]
