The proliferation of "species" – often placed in the "wrong" genus, has impacted all taxonamic work in 20th Century hepaticology. The same species may have been described under 3-4, or more, genera; under a single genus, such as Lepidolejeunea, species have been described in some 10-12 genera. The greatest outstanding need is for a synthesis that attempts to critically define families and, in particular, genera and subgenera. For more than a century nobody has attempted such a synthesis. This work attempts to answer this need by providing a modern synthesis of what we have learned, mostly in the second half of the twentieth century, about the families and genera of liverworts. It deals primarily with the conceptual bases that underlie a modern classification of the Hepaticae: the boundaries of suborders, families and genera are drawn by evaluating modern criteria. In such an evaluation emphasis is on features largely unused prior to 1950: ramification patterns and branch origins; capsule wall anatomy; seta and stem anatomy; oil-bodies and cell wall criteria.
This volume contains 211 figures, drawn by the author, which illustrate these features and also show many taxa in drawings illustrating basic aspects of each genus. Almost all larger groups were studied from living plants and emphasis is on liverworts as living organisms. The larger genera of Hepaticae are each illustrated with several plates and emphasis is on "key" genera which occupy critical phylogenetic positions, such as Lepidozia, Pseudocephalozia and Paracromastigum. No attempt is made at species diagnoses but generic boundaries, in larger genera, are defined by illustrating several species per genus. Except for genera with numerous species, keys to species are provided. In numbered annotations diverse problems, such as generic relationships and boundaries, are discussed; key species are often treated at length. As noted in the Introduction, since all taxa cannot be illustrated and/or described, for all larger genera the "type" method is used: boundaries are established by treating (and illustrating) key taxa so as to draw logical boundaries for each genus – and family.

Now part 1 of Austral Hepaticae is published. It's one of these typical projects of Schuster, nearly nobody else can do it or will be able to do it in future. The now published volume and two more planned volumes will cover the Hepatic flora of landmasses which were once united to form Gondwanaland. But the treatment is heavily "biased" towards a treatment of South American and Australasian-Pacific hepatic floras, mostly on taxa which are of Gondwanan origin.
Part 1 covers the Calobryales (Haplomitrium) and Jungermanniales (Vetaformaceae, Lepicoleaceae, Herbertaceae, Grolleaceae, Trichocoleaceae, Trichotemnomaceae, Antheliaceae, Lepidoziaceae, Phycolepidoziaceae, Calypogeiaceae). Excellent line drawings, combined with full descriptions and keys are most valuable and useful for everybody working on this item. The study is filling a huge gap since there is no overall survey of austral Hepatics. Till now everybody has to look on a widely scattered literature, which often is hardly accessible. If there will be published the relevant literature in part 3, a broad bibliography on this item is available. Also very informative is the chapter on the classification of the Hepaticae (pp. 10-14), a general statement of the author's "own" bryophyte group.
This Austral Hepaticae should be available in any botanical library, as every botanist or bryologist dealing with Southern Hemisphere hepatics must contact this book."
