Morphology

odd-pinnate + leaf

The phrase is directly compositional: 'odd-pinnate' (having a single terminal leaflet / an odd number of leaflets) modifies 'leaf', so the overall meaning — a leaf with a terminal leaflet producing an odd number of leaflets — follows immediately from the parts. Although botanical terms are specialised, the adjective+noun structure and literal semantics make this immediately derivable for learners who know the constituent meanings.

Etymology

Odd-pinnate leaf names a leaf that has many small leaflets along a central stem and one extra leaflet at the tip. Pinnate means the leaflets line up like a feather, and odd shows the leaf has an 'odd number' of leaflets because of that single tip leaflet.
