Notes. – Lejeunea rotundifolia is a robust Andean species with orbicular leaves, very large and suborbicular underleaves with a short-bifid apex and strongly auriculate bases, and stems with 4–6 cell wide ventral merophytes (REINER-DREHWALD, 2005). Taxilejeunea auriculata is identical to L. rotundifolia and a synonym. The specimen collected by Allioni is chosen here as the lectotype of T. auriculata as it was illustrated in STEPHANI (1985: tab. 9997).
