Some of the Cassinopsis ilicifolia leaves in picture appear to have entire margins, while others show scattered, sharp-tipped teeth. There are sometimes teeth present that are not seen by being rolled under, while margins may also be entire.

The opposite, simple leaves are narrowly ovate and hairless, growing on petioles of up to 8 mm long that are sometimes hairy. The leaf apex tapers to an acute point or drip-tip, the base being rounded to broadly tapering.

There is a slight, but distinct fold along the leaf’s recessed midrib. The faint lateral veins angle upwards to the margins without visibly reaching them by joining each other in forward curves.

The lower surfaces of the thinly textured leaves are dull, lacking the fresh green to glossy green shine of the upper ones. Leaf dimensions are 4 mm to 6 mm by 2 mm to 2,5 mm (Coates Palgrave, 2002; Schmidt, et al, 2002).
