Phylloclades:
(i) They are flattened (e.g., Opuntia, Euphorbia), or cylindrical green stems of unlimited growth which have taken over the function of photosynthesis.
(ii) True leaves are caducous.
(iii) Formation of phylloclades helps the plant to grow, the in dry habitats because transpiration is little from stem.
Cladodes (Cladophylls):
(i) They are green stems of limited growth which have taken over the function of photosynthesis from the leaves.
(İİ) The true leaves are. reduced to scale or spines.
(İİİ) Cladodes are a modification to reduce transpiration. e.g., Asparagus, Ruscus.
