Frond
collection of leaflets on a plant / From Wikipedia, the free encyclopedia
A frond is a large, divided leaf.[1]
The leaves of ferns are referred to as fronds.[2] Some botanists only use this term for ferns.[3] Other botanists also use the term 'frond' for the large leaves of cycads, as well as palms (Arecaceae) and various other flowering plants, such as mimosa or sumac.[4][5]
"Frond" is commonly used to identify a large, compound leaf. If the term is used for the leaves of ferns and algae, it can be applied to smaller and undivided leaves.
