A new species of Ceratolejeunea (Marchantiophyta, Lejeuneaceae) from Cuba

Abstract
A new species of Ceratolejeunea (Spruce) J.B.Jack et Steph. from Baracoa, Cuba is described and illustrated. The diagnostic characters of Ceratolejeunea baracoensis are its combination of moniliate and seriate ocelli on single leaves, leaf and underleaf margins with weak denticulations formed by the projecting corners of two adjacent cells (Allorgella-type denticulations), underleaves bifid to 2/3, underleaf lobes lanceolate, 4 cells wide at base and 6-7 cells long.
