Die vorliegende Studie stellt mit Mitteln der klassischen
morphologisch-anatomischen Merkmalsanalyse an 77 Gattungen eine
phylogenetische Rekonstruktion der Jubulineae mit Schwerpunkt bei den
Lejeuneaceae und Jubulaceae dar.
Erstmalig wurden 20 Sporophyten-Merkmale neu für die Wissenschaft
erhoben, l2 bei einigen Gattungen bereits beobachtete Strukturen als
Merkmale kodiert und 9 bereits in der Phylogenie verwendete Merkmale
ausgeweitet und im Kontext bereits vorhandener Daten diskutiert. Die
Sporophyten von 21 Gattungen wurden erstmalig bearbeitet, von l4
Gattungen wurden die Sporophyten fast vollständig neu bearbeitet, da
nur zu maximal drei Merkmalen Literaturangaben vorhanden waren. Bei
weiteren 42 Gattungen wurden bis über 70% der Merkmale neu erarbeitet
oder mit umfangreichen neuen Daten ergänzt.
Die Sporophyten-Merkmale können systematisch verwendet werden und
tragen zu einer natürlicheren Einteilung der untersuchten Gruppe bei.
In einer kladistischen Analyse konnte gezeigt werden, daß in allen
Untersuchungen mit kombinierten Sporophyten- und
Gametophyten-Merkmalen Goebeliella (Goebeliellaceae) separat in
der Nähe der Außengruppe Porella steht. Die Jubulaceae bilden
die Schwestergruppe zu den monophyletischen Lejeuneaceae. Innerhalb
der Lejeuneaceae steht Nipponolejeunea (Subfam.
Nipponolejeunoideae) als Schwestergruppe zur Kerngruppe. In dieser
Gruppe befinden sich basal die Ptychantheae als paraphyletische
Schwestergruppe zu den monophyletischen Lejeuneoideae, diese bestehen
aus den Stictolejeuninae, den monophyletischen Brachiolejeuninae und
den monophyletischen Lejeuneae s.l.. Innerhalb der Lejeuneae bilden
die „Cololejeuneen“ und die „Omphalantheen“ monophyletische
Gruppen. Die „Tuyamaelleen“ erwiesen sich jedoch als polyphyletisch
durch die Sonderstellung von Haplolejeunea.
This study presents a phylogenetic analysis of 77 genera of Jubulaceae
and Lejeuneaceae (Jubulineae) and related groups, using morphological
and anatomical characters of gametophytes and sporophytes.
The sporophytes of 21 genera were examined for the first time, those
of 14 other ones were almost completely newly described. For
additional 42 genera more than 60% of the characters were either
re-examined or complemented with more comprehensive new data.
The study shows that sporophytic characters are important to provide a
natural classification of the investigated group.
The phylogenetic analysis showed that Goebeliellaceae are the sister
group of the Porellaceae and Jubulaceae of the (monophyletic)
Lejeuneaceae.
Within Lejeuneaceae the Nipponolejeunea (subfam. Nipponolejeunoideae)
form a sister group to the core group, based on the paraphyletic
Ptychanthoideae and the monophyletic Lejeuneoideae. Within the
Lejeuneae the “Cololejeunoideae” and the “Omphalanthus-complex” form
monophyletic groups, the “Tuyamaelloideae” however, turn out to be
polyphyletic when Hapolejeunea is included.

The study presents the relationship of species of 77 genera of
Jubulaceae and Lejeuneaceae and related groups, based on morphological
and anatomical characters.
The author shows that sporophytic characters are most
important. Beside this,sporophytes of 21 genera were examined for the
first time. Due to the systematic the Goebeliellaceae are placed near
Porella, and the Jubulaceae are a sister group of
theLejeuneaceae. Most valuable is the presentation of new
morphological and anatomical dates.

Morphologically, the Lejouneaceae are one of the most diverse bryophyte
families in existence. Hepaticologists continue trying to understanding how
this startling display of variability can be used to unlock the evolutionary
history of the family. Perhaps due to the conspicuousness and aesthetic allure
of the gametophyte, its characters have been consistently over-represented
relative to those of the more ephemeral sporophyte in systematic studies of
the Lejouneaceae. In this book, Gabriele Weis demonstrates that the neglected
diploid generation offers a viable source of data for reconstructing
evolutionary relationships both within the family, and among other closely
allied Jungermannalian taxa. The book includes a large phylogenetic analysis
based on sporophytic features, and offers a refreshing taxonomic alternative
in an era where morphology-based phylogenies too consistently take a back seat
to gene-genealogies.
Weis has organized her book into four sections:
1) an introduction detailing the taxa used in her survey, and including a
45-word glossary of salient anatomical terms, as well as an historical review
(1838 to the present) of research previously conducted on sporophytes of the
Lejouneaceae and Jubulaceae;
2) a conspectus of written descriptions and SEM photographs of sporophyte
features (e.g., foot, seta, inner and outer capsule structure, elator, and
spore surface) from 231 species in 77 genera representing four families;
3) a phylogenetic analysis based on 36 coded sporophyte features from more
than 70 taxa; and
4) a summary of previously published broad-scale systematic research on the
Jungermanniales,
I found Weis's concise summaries of earlier hypotheses on the phylogeny of the
Jungermanniales not only place her new results in an historical context, but
also offer the reader insight into the myriad phylogenetic hypotheses
generated over nearly two centuries of taxonomic research. Her quantitative
(e.g., cladistic) approach to her analyses demonstrates strong support of many
traditionally accepted sub-familial relationships within the Lejouneaceae. In
my opinion, one of the more interesting results is the discovery of
Cololejeunioideae (e.g., facultative epiphyllous taxa) as a well-supported
monophyletic clade sister to the sprawling Lejeunioideae complex.
The historical summary ends with a treatment of sub-familial taxonomy within
the Lejouneaceae differing only marginally from other recent treatments.
Although we have a long road ahead to understanding the full extent of
evolutionary relationships within the Lejeunaceae, Gabriele Weis has
convincingly demonstrated that patterns in sporophyte morphology are important
pieces of the large taxonomic puzzle presented by this fascinating family of
hepatics. For hepaticologists who truly understand the anonymous quote on the
book's title page ("Small things mean nothing, till you see them"), her book
is a necessity.
