Pinnatifid is a botanical term used to describe leaves or lobes that are deeply divided, with the smaller divisions arranged along the main vein. Some synonyms for pinnatifid include pinnatisect, which describes leaves that are deeply cut into numerous segments attached to the central axis; pinnately lobed, which indicates a leaf that is divided into several lobes along the central axis; and pinnate, which is used more broadly to describe any leaf that has numerous leaflets attached along the central axis. Other related terms include palmately lobed (for leaves divided into several lobes diverging from a central point), bipinnatifid (for twice-divided leaves), and tripinnatifid (for three times divided leaves).
