Petal

Petals are considered by botanists to be leaves, albeit highly modified leaves. They comprise the corolla of a flower. 

Petals that are completely separate from each other are termed "distinct". (Figure A)

Petals that are completely attached to each other to form a different-shaped entity are thought to be "fused".  (Figure B)

Petals that are partially attached to each other may be considered to have "lobes".  (Figure C)
