"Ascarina" trees produce elliptic leaves with varying size and vascular structures. The leaf margins are lightly serrated, and the petiole of the leaf is quite short. These leaves also have the highest vein order of four to five, in a combination of brochidodromous (where secondary veins do not terminate at leaf margin, and instead form joined arches along the margin) and craspedodomous (where secondary veins terminate at leaf margins) venations. The structures on leaf margins of "Ascarina" share general shape, size and with the other genera of "Chloranthaceae". They differ from the other genera in the festooned craspedodomous venation, which is a unique feature of "Ascarina".
