Morphology

decompound + leaf

The meaning is directly compositional: 'decompound' (divided into smaller compound parts) modifies 'leaf' (a plant leaf), so the phrase denotes a leaf with multiple levels of subdivision. Although botanical and somewhat technical, the sense follows transparent morphological logic and would be derivable by a B1 learner who knows the constituent words.

Etymology

Decompound leaf comes from the idea of a compound leaf whose parts are divided again, like a feather made of smaller feathers. So, it means 'a leaf divided into parts that are themselves compound'.
