Abstract : The second volume of this work treats a large number of 'critical' taxa in four of the most complex and difficult of the families of Jungermanniales: the Lepidoziaceae and Calypogeiaceae (comprising the Suborder Lepidoziinae) and the Lophoziaceae and Jungermanniaceae (comprising the two largest and most difficult families of the Suborder Jungermanniinae). Each taxon is illustrated by numerous individual figures and certain particularly difficult species are analyzed in detail, in order that the possible perimeters of variability be established for certain highly technical taxa. It is hoped that, by extrapolation from such treatments, a sane and genetically well-defined taxonomic treatment of the various groups will result.
