Studies in the liverwort family Aneuraceae (Metzgeriales) from southern Africa. 5. Riccardia amazonica

Abstract

Riccardia amazonica (Spruce) Schiffn. ex Gradst. is described and illustrated, as fresh material from southern Africa has recently come to hand. Several tropical African species of the genus had previously been placed in synonymy with this South American species; their type specimens have now also been studied.
