Definition
'Bipinnatifid' describes a leaf that is both bipinnate and deeply lobed or cleft. Picture a feather where the leaflets are themselves deeply cut into smaller lobes. It's similar to bipinnate, but with even more intricate divisions. This describes a complex and finely dissected leaf structure. The distinction is that the divisions are closer to the central vein. The key is both the feather-like structure and the deep lobes.
