Phylloclade

Phylloclades and cladodes are flattened, photosynthetic shoots, which are usually considered to be modified branches. The two terms are used either differently or interchangeably by different authors. Phyllocladus, a genus of conifer, is named after these structures. Phylloclades/cladodes have been identified in fossils dating from as early as the Permian.

Not to be confused with Cladophyll.
