Bipinnate
/by-PIN-ayt/🍃 Leaf Shapes●● Intermediate
Also known as: twice-pinnate, doubly compound, twice-compound
A leaf that is doubly compound — the primary leaflets are themselves pinnately divided into secondary leaflets. Bipinnate leaves create a fine, feathery texture and are characteristic of many legumes (Fabaceae), including honey locust, mimosa, and jacaranda. The overall effect is a delicate, fern-like appearance that provides dappled shade.
Etymology
Latin bi (two, double) + pinnatus (feathered, winged)
