Morphology
bijugous + leaf
The adjective 'bijugous' etymologically signals 'two-paired' (bi- = two + jugous ≈ paired), so combined with 'leaf' the phrase literally denotes a leaf with two pairs of leaflets, giving a compositional clue. However, 'bijugous' is a low-frequency, technical botanical term and the element 'jugous' is not familiar to B1 learners, so the meaning is only partially predictable without specialist knowledge.
Etymology
Bijugous leaf comes from parts that mean bi ('two') and jugous ('pairs'). Imagine a short central stem with two pairs of small leaflets, one pair above the other, and that picture explains why it means 'a leaf with two pairs of leaflets'.
