Answer :

Ans: Leaves which have epiphyllous buds help in vegetative reproduction. Such leaves are called as reproductive leaves. In Bryophyllum, notches of leaf margins have epiphyllous buds which upon shedding strike adventitious roots and develop into new plants. In Scilla, epiphyllous buds arise at the leaf tip and in Begonia from the wounded regions of leaf.
