Bipinnate - English Definition & Meaning

Definition

'Bipinnate' describes a compound leaf where each leaflet is further divided in a pinnate manner. Imagine a feather, then imagine each of the barbs of the feather also being a smaller feather. It's a highly divided and intricate leaf structure. This occurs in plants that require complex structural supports. 'Bi-' indicates two levels of division and 'pinnate' refers to the feather-like arrangement. It's like a compound leaf on top of another compound leaf.

Etymology

The word 'bipinnate' combines 'bi-' (two) and 'pinnate' (feather-like). 'Pinnate' comes from the Latin 'pinna,' meaning 'feather' or 'wing.' This etymology directly reflects the word's meaning: twice-divided in a feather-like pattern. The roots clearly indicate the structure being described. Knowing this helps visualize the complex leaf structure.
