Understanding Bipinnatifid Leaves: A Guide to Botany
Bipinnatifid is a term used in botany to describe a leaf that has two distinct pinnae (leaflets) attached to a common rachis (midrib). The word "bipinnatifid" comes from the Latin words "bi-" meaning "two," "pinna" meaning "wing," and "-tid" meaning "having."
In other words, a bipinnatifid leaf is one that has two pairs of leaflets attached to a central stem. Each pair of leaflets is called a pinna, and they are arranged in an opposite or alternate pattern along the rachis. This type of leaf structure is commonly found in plants of the family Asteraceae, such as daisies and sunflowers.
