Cheilolejeunea lamyi sp. nov., a Fossil Lejeuneaceae from Miocene Dominican Amber

Abstract An inclusion in Miocene Dominican amber is described as Cheilolejeunea lamyi, sp. nov. The fossil resembles the extant Cheilolejeunea rigidula but differs in the partly subacute leaf lobes, often apiculate underleaf lobes, and the slightly more acute lobes of the bracteole. The two other Cheilolejeunea species in Dominican amber, Cheilolejeunea antiqua and C. suzannensis, have entire rather than bifid underleaves.
