Matoniaceae A family of ferns, whose fronds, which are borne on rhizomes, have a characteristic dichotomous branching which produces a fan-like form. The sori are gradate, superficial, rounded, and on the underside of the pinnae; unlike the related Gleicheniaceae, they have rounded indusia. The anatomy of the rhizome is a complex solenostele, with several concentric cylinders of vascular tissue. There are 2 genera, with 4 species, found in Malesia.
