Cladode
A cladode is a specialised branch that has the appearance of, and functions of, a leaf: wide, flat and photosynthetic.
The racquets of the prickly pear (Opuntia ficus-indica) or the leaves of the butcher's broom (Ruscus aculeatus) are in fact cladodes.
What seem to be the leaves of this Semele androgyna are actually branches. There is a clue to be certain: only branches produce flowers, never leaves! © Scott Zona, Wikimedia CC by 2.0
