The phylloclade is the special modified photosynthetic stem in xerophytes. It is a green flattened or cylindrical structure that has distinct nodes and internodes. To check the rate of transpiration stems get modified and become flattened to carry out photosynthesis as leaves convert into spines thorns, a lesser number of stomata, etc. Phylloclades retain water in the form of mucilage. Examples: -Opuntia, Ruscus, etc.
