Part II of Austral Hepaticae treats two of the largest and most complex suborders of the order Jungermanniales. The first suborder, the Cephaloziineae, includes some four families, of which the largest and most complex, the Cephaleziaceae, contains five subfamilies, with some 12 genera. The second suborder, the Jungermannlineae, includes some six families, ten subfamilies, and 40 genera. In total, some 69 genera are studied. As in Part I, each genus/ subgenus is illustrated with both gametophytic and sporophytic details, and usually cytological details (drawn from the living plant). Over 2700 individual figures on 224 plates, drawn (with isolated exceptions) by the author, often from living plants, have been prepared for this volume. The work thus is a summation of what the author has learned in over four decades, in field and in laboratory studies, in all areas of the Southern Hemisphere. Much of the technical data are relegated to Annotations, in which a mass of data is presented, sing specific species to round out our comprehension of the verse genera. As in Part I of this work, synoptic keys for smaller genera keys are usually presented.
