Fruits enclosed in the persistent, papery, calyx lobes. Seeds small, about 1.5 x 2 mm. Embryo U-shaped.

At the tenth leaf stage: leaf blade ovate to cordate, apex acute, base truncate or cuneate, margins usually with a few coarse teeth. Upper surface of the leaf blade and margin clothed in pale septate hairs but very few on the underside of the leaf blade. Stem longitudinally ridged or channelled.
