Morphology

compound + leaf

The meaning 'a leaf consisting of several distinct leaflets' is directly and transparently derived from combining 'compound' (composed of several parts) with 'leaf' (the plant organ). This is a straightforward compositional botanical term and similar constructions exist across languages, so a B1 learner who knows both words would readily infer the meaning.

Etymology

Compound leaf names a plant leaf that is compound — made of several small leaflets joined to a single stalk. Imagine many little parts attached to one stem so they act as 'one leaf', and that is why the phrase means a single leaf divided into joined parts.
