Leaves.
Byophylum are also known as air plants. In Bryophylum, reproduction occurs through asexual means, specifically, through vegetative propagation of leaves. The leaves of Bryophylum are broad possessing notches at its margins, these are the locations from which buds(notches) arise. The buds are termed as epiphyllous buds which have the potential to produce new plants having shoots, small leaves and adventitious roots. The newly formed plants can then detach from teh leaves to grow into a mature plant once it touches the soil.
This is very helpful for me
