Morphology
The phrase is fully compositional: 'cuneate' (wedge-shaped, narrowing toward the base) modifies 'leaf' (a plant organ), so the meaning 'a wedge-shaped leaf' follows directly from the constituents. Although 'cuneate' is a low-frequency, technical adjective, the adjective+noun structure is regular and therefore immediately interpretable by a learner who knows both words.
Etymology
Cuneate leaf comes from an old word for 'wedge', so cuneate tells you the shape. It means a leaf with a narrow, pointed base that looks like a small wedge fitting into the stem, so the name now means 'a leaf shaped like a wedge'.
