Cover design: WMXDesign, Heidelberg, Germany Typesetting and production: LE-TEX Jelonek, Schmidt & Vöckler GbR, Leipzig, Germany Printed on acid-free paper 31/3150/YL – 5 4 3 2 1 0 Preface The present volume contains treatments of various eudicot orders which all are strongly supported in molecular analyses. A first group comprises Proteales, Buxales and the enigmatic Sabiaceae which, together with Ranunculales and Trochodendrales, treated earlier in Vol. II of this series, represent the basal grade of early-diverging eudicots. Al- though all of them have clearly tri-orate pollen, making them eudicots, they otherwise lack the strict eudicot floral organisation, particularly with regard to flower merosity, phyllotaxis and perianth structure. The same is true for the order Gunnerales which, however, according to findings of molecular systematics, forms part of the strongly sup- ported core eudicots. All these orders to some extent bridge the morphological gap be- tween basal angiosperms and typical core eudicots. Plesiomorphic floral traits, although less pronounced, are also found among the isolated but clearly core eudicotyledonous Saxifragales, treated in this volume, and particularly in the early-diverging woody fam- ilies of this order. Some of these latter families were included in Vol. II, which followed a classification used prior to the discovery of the modern concept of Saxifragales. The exact interrelationships among the early-diverging eudicot orders still remain largely unresolved. This is even more true for many of the core eudicot orders included in the present volume, i.e. Vitales, Crossosomatales, Geraniales, Zygophyllales and Myrtales, and also for two of the families not assigned to order, i.e. Huaceae and Picramniaceae. A possible relationship between Dilleniaceae and woody Caryophyllales, as suggested by recent studies, opens an interesting new perspective on the evolution of this family. Included in this volume are two subclades of the vast Malpighiales. These are Passi- floraceae with two satellite families, and Clusiaceae/Hypericaceae with Podostemaceae, which recently have been identified as very close relatives. My deep thanks go to all authors of this volume, who have provided such highly in- teresting and scholarly contributions, and to all those who have freely shared additional information and/or have commented on earlier drafts of the contributions.

    Well-Known Plants in Each Angiosperm Order

    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers.

    Outline of Angiosperm Phylogeny

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report.

    Full of Beans: a Study on the Alignment of Two Flowering Plants Classification Systems

    Full of beans: a study on the alignment of two flowering plants classification systems Yi-Yun Cheng and Bertram Ludäscher School of Information Sciences, University of Illinois at Urbana-Champaign, USA {yiyunyc2,ludaesch}@illinois.edu Abstract. Advancements in technologies such as DNA analysis have given rise to new ways in organizing organisms in biodiversity classification systems. In this paper, we examine the feasibility of aligning two classification systems for flowering plants using a logic-based, Region Connection Calculus (RCC-5) ap- proach. The older “Cronquist system” (1981) classifies plants using their mor- phological features, while the more recent Angiosperm Phylogeny Group IV (APG IV) (2016) system classifies based on many new methods including ge- nome-level analysis. In our approach, we align pairwise concepts X and Y from two taxonomies using five basic set relations: congruence (X=Y), inclusion (X>Y), inverse inclusion (X<Y), overlap (X><Y), and disjointness (X!Y). With some of the RCC-5 relationships among the Fabaceae family (beans family) and the Sapindaceae family (maple family) uncertain, we anticipate that the merging of the two classification systems will lead to numerous merged solutions, so- called possible worlds. Our research demonstrates how logic-based alignment with ambiguities can lead to multiple merged solutions, which would not have been feasible when aligning taxonomies, classifications, or other knowledge or- ganization systems (KOS) manually. We believe that this work can introduce a novel approach for aligning KOS, where merged possible worlds can serve as a minimum viable product for engaging domain experts in the loop. Keywords: taxonomy alignment, KOS alignment, interoperability 1 Introduction With the advent of large-scale technologies and datasets, it has become increasingly difficult to organize information using a stable unitary classification scheme over time.

Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

The University of British Columbia Vancouver, Canada http://www.library.ubc.ca/spcoll/thesauth.html ABSTRACT Dioecy, the breeding system with male and female function on separate individuals, may affect the ability of a lineage to avoid extinction or speciate. Dioecy is a rare breeding system among the angiosperms (approximately 6% of all flowering plants) while hermaphroditism (having male and female function present within each flower) is predominant. Dioecious angiosperms may be rare because the transitions to dioecy have been recent or because dioecious angiosperms experience decreased diversification rates (speciation minus extinction) compared to plants with other breeding systems.

Their study presented a set of new fossils within the order, generated a chronogram for Geraniales and other rosid orders using fossil-based priors on five nodes, demonstrated an Eocene radiation of Geraniales (and other rosid orders), and argued for more recent (Pliocene–Pleistocene) and climate-linked diversification of genera in the five recognized families relative to previous studies. As a result of very young ages for the crown of Geraniales and other rosid orders, unusual relationships of Geraniales to other rosids, and apparent nucleotide substitution saturation of the two gene regions, we conducted a broad series of BEAST analyses that incorporated additional rosid fossil priors, used more accepted rosid ordinal
