Definition:
(n.) A leaf, usually smaller than the true leaves of a plant, from the axil of which a flower stalk arises.
(n.) Any modified leaf, or scale, on a flower stalk or at the base of a flower.
Example Sentences:

(3) Cotton bract tannin is a potent stimulus for platelet aggregation and secretion.
(4) Byssinosis, COPD, cotton fever and cotton pneumoconiosis may be different types of responses due to the different duration of exposure, the different parts of bronchial tree (upper respiratory tract, small airway, and respiratory part) where deposition occurs, and the different components of cotton dust (broken cotton fibers, bracts, pericarps, bacteria, and fungi).

(15) The provenance of bristles and bracts suggests that the bristle cells move into their final positions.
(16) Mill workers are exposed to bract which has weathered in the field, but it is not known whether biologic effects of bract are due to intrinsic plant compound(s) or to contamination occurring during field weathering.
