Abstract

Lejeunea pocsiana, a new species from Fiji, is described and illustrated. It is characterized by its large size, robust stems, ventral merophyte 4-8 cells wide, broadly ovate to triangular-ovate leaves with a rounded leaf apex, subquadrate and almost flat lobules with two distinctly differentiated teeth, bifid underleaves with cordate to slightly auriculate bases, and leaf cells with smooth cuticle and poorly developed trigones. A key to Lejeunea species that have robust stems with a (3-)4-8-cell-wide ventral merophyte is presented.
