Explanation

A small bract is called a bracteole or bractlet. Technically this is any bract that arises on a pedicel instead of subtending it as in Adhantoda. Bracts that appear in a whorl subtending an inflorescence are collectively called an involucre. An involucre is a common feature beneath the inflorescences of many Apiaceae, Asteraceae, Dipsacaceae and Polygonaceae.
