Present and persistent

A bracteole, or bracteoles, are present (although they may be minute) beyond anthesis.

Present but caducous

Bracteole(s) are present, but are early deciduous (generally not persisting until anthesis), sometimes leaving a scar (may also appear to be entirely absent).

Entirely absent

Bracteoles are entirely absent, or are very readily deciduous and appear to be absent.
