| For most families of plants, the
small leaflets that comprise the involucre are called "bracts". With
regard to composite family species, the distinction is made between the
leaflets comprising the involucre (i.e., "phyllaries") and the leaflets attached
to the peduncle (i. e., "bracts").
(Note that some scholars use the term "involucral bracts" to
refer to phyllaries.) Bract: (A) A small leaflet at the base of a flower or attached to the peduncle. Bracteal: (A) Pertaining to bracts. Phyllary: (B) The small bracteal leaflets comprising the involucre of a composite flower head. Shown below, left:
