Phylloclades::
(a)They are flattened (e.g., Opuntia, Euphorbia).
(b)They are green stems of unlimited growth which have taken over the function of photosynthesis.
©True leaves are caducous.
(d)Formation of phyllodades helps the plant to grow in dry habitats because transpiration is little from the stem.
Cladodes(Cladophylls):
(a)They are green stems of limited growth which have taken over the function of photosynthesis from the leaves.
(b)The true leaves are reduced to scale or spines.
©In’Asparagus, the cladodes are slightly flattened, fleshy, straight or curved pointed structures which develop in clusters in the axils of scale leaves.
(d)The main stem possesses leaf spines.
(e)Cladodes are a modification to reduce transpiration.
e.g., Asparagus, Ruscus.
