A new species of symphyogyna (pallaviciniaceae, marchantiophyta) from the northern andes of Ecuador notes on the bryophytes of Ecuador IV

Abstract:

A new species of Symphyogyna, S. caduciloba, is described, based on the combination of ascending growth form, deeply lobate thallus, variable lobe tips with a small, 1-2-celled apical tooth which is sometimes replaced by a slime papilla, and caducous thallus lobes. Relations with similar species are discussed and a key to the lobate species of Symphyogyna in Ecuador is presented.
