Herendeen1,* and Fabiany Herrera* *Chicago Botanic Garden, 1000 Lake Cook Road, Glencoe, Illinois 60022, USA Editor: Michael T. Dunn Premise of research. Fossil leaves from the early Eocene Green River Formation of Wyoming and late Eo- cene Florissant Formation of Colorado have been studied and described here as two species in the monospe- cific extant genus Arcoa (Leguminosae, subfamily Caesalpinioideae). The single living species of Arcoa is en- demic to the Caribbean island of Hispaniola. The species from Florissant has been known since the late 1800s but has been incorrectly treated as several different legume genera. Methodology. The compression fossils were studied using standard methods of specimen preparation and microscopy. Fossils were compared with extant taxa using herbarium collections at the Field Museum and Smithsonian Institution. Pivotal results. The fossil bipinnate leaves exhibit an unusual morphological feature of the primary rachis, which terminates in a triad of pinnae, one terminal flanked by two lateral pinnae, all of which arise from the same point at the apex of the rachis. This feature, combined with other features that are diagnostic of the family Leguminosae or subgroups within it, allows the taxonomic affinities of the fossil leaves to be definitively deter- mined as representing the extant genus Arcoa, which is restricted to the Caribbean island of Hispaniola today. -
A Phylogeny of Legumes (Leguminosae) Based on Analysis of the Plastid Matk Gene Resolves Many Well-Supported Subclades Within the Family1
American Journal of Botany 91(11): 1846±1862. 2004. A PHYLOGENY OF LEGUMES (LEGUMINOSAE) BASED ON ANALYSIS OF THE PLASTID MATK GENE RESOLVES MANY WELL-SUPPORTED SUBCLADES WITHIN THE FAMILY1 MARTIN F. W OJCIECHOWSKI,2,5 MATT LAVIN,3 AND MICHAEL J. SANDERSON4 2School of Life Sciences, Arizona State University, Tempe, Arizona 85287-4501 USA; 3Department of Plant Sciences, Montana State University, Bozeman, Montana 59717 USA; and 4Section of Evolution and Ecology, University of California, Davis, California 95616 USA Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from 37 of 39 tribes, and four outgroup taxa from eurosids I supports many well-resolved subclades within the Leguminosae. These results are generally consistent with those derived from other plastid sequence data (rbcL and trnL), but show greater resolution and clade support overall. In particular, the monophyly of subfamily Papilionoideae and at least seven major subclades are well-supported by bootstrap and Bayesian credibility values. These subclades are informally recognized as the Cladrastis clade, genistoid sensu lato, dalbergioid sensu lato, mirbelioid, millettioid, and robinioid clades, and the inverted-repeat-lacking clade (IRLC). The genistoid clade is expanded to include genera such as Poecilanthe, Cyclolobium, Bowdichia, and Diplotropis and thus contains the vast majority of papilionoids known to produce quinolizidine alkaloids. The dalbergioid clade is expanded to include the tribe Amorpheae. The mirbelioids include the tribes Bossiaeeae and Mirbelieae, with Hypocalypteae as its sister group. The millettioids comprise two major subclades that roughly correspond to the tribes Millettieae and Phaseoleae and represent the only major papilionoid clade marked by a macromorphological apomorphy, pseu- doracemose in¯orescences. -
Contributions to the Solution of Phylogenetic Problem in Fabales
Research Article Bartın University International Journal of Natural and Applied Sciences Araştırma Makalesi JONAS, 2(2): 195-206 e-ISSN: 2667-5048 31 Aralık/December, 2019 CONTRIBUTIONS TO THE SOLUTION OF PHYLOGENETIC PROBLEM IN FABALES Deniz Aygören Uluer1*, Rahma Alshamrani 2 1 Ahi Evran University, Cicekdagi Vocational College, Department of Plant and Animal Production, 40700 Cicekdagi, KIRŞEHIR 2 King Abdulaziz University, Department of Biological Sciences, 21589, JEDDAH Abstract Fabales is a cosmopolitan angiosperm order which consists of four families, Leguminosae (Fabaceae), Polygalaceae, Surianaceae and Quillajaceae. The monophyly of the order is supported strongly by several studies, although interfamilial relationships are still poorly resolved and vary between studies; a situation common in higher level phylogenetic studies of ancient, rapid radiations. In this study, we carried out simulation analyses with previously published matK and rbcL regions. The results of our simulation analyses have shown that Fabales phylogeny can be solved and the 5,000 bp fast-evolving data type may be sufficient to resolve the Fabales phylogeny question. In our simulation analyses, while support increased as the sequence length did (up until a certain point), resolution showed mixed results. Interestingly, the accuracy of the phylogenetic trees did not improve with the increase in sequence length. Therefore, this study sounds a note of caution, with respect to interpreting the results of the “more data” approach, because the results have shown that large datasets can easily support an arbitrary root of Fabales.

Combined Phylogenetic Analyses Reveal Interfamilial Relationships and Patterns of floral Evolution in the Eudicot Order Fabales
Cladistics Cladistics 1 (2012) 1–29 10.1111/j.1096-0031.2012.00392.x Combined phylogenetic analyses reveal interfamilial relationships and patterns of floral evolution in the eudicot order Fabales M.

We combine published molecular data for the chloroplast regions matK and rbcL with 66 morphological characters surveyed for 73 ingroup and two outgroup species, and use Parsimony and Bayesian approaches to explore matrices with different missing data. All combined analyses using Parsimony recovered the topology Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). Bayesian analyses with matched morphological and molecular sampling recover the same topology, but analyses based on other data recover a different Bayesian topology: ((Polygalaceae + Leguminosae) (Quillajaceae + Surianaceae)). We explore the evolution of floral characters in the context of the more consistent topology: Polygalaceae (Leguminosae (Quillajaceae + Surianaceae)). This reveals synapomorphies for (Leguminosae (Quillajaceae + Suri- anaceae)) as the presence of free filaments and marginal ⁄ ventral placentation, for (Quillajaceae + Surianaceae) as pentamery and apocarpy, and for Leguminosae the presence of an abaxial median sepal and unicarpellate gynoecium. An octamerous androecium is synapomorphic for Polygalaceae. The development of papilionate flowers, and the evolutionary context in which these phenotypes appeared in Leguminosae and Polygalaceae, shows that the morphologies are convergent rather than synapomorphic within Fabales. -
Reproductive Morphology of Sargentodoxa Cuneata (Lardizabalaceae) and Its Systematic Implications
Reproductive morphology of Sargentodoxa cuneata (Lardizabalaceae) and its systematic implications. By: Hua-Feng Wang, Bruce K. Kirchoff and Zhi-Xin Zhu Wang, H.-F., Kirchoff, B.

No further reproduction is authorized without written permission from Springer-Verlag. This version of the document is not the version of record. Figures and/or pictures may be missing from this format of the document. *** Abstract: The reproductive morphology of Sargentodoxa cuneata (Oliv) Rehd. et Wils. is investigated through field, herbarium, and laboratory observations. Sargentodoxa may be either dioecious or monoecious. The functionally unisexual flowers are morphologically bisexual, at least developmentally. The anther is tetrasporangiate, and its wall, of which the development follows the basic type, is composed of an epidermis, endothecium, two middle layers, and a tapetum. The tapetum is of the glandular type. Microspore cytokinesis is simultaneous, and the microspore tetrads are tetrahedral. Pollen grains are two-celled when shed. The mature ovule is crassinucellate and bitegmic, and the micropyle is formed only by the inner integument. Megasporocytes undergo meiosis resulting in the formation of four megaspores in a linear tetrad. The functional megaspore develops into an eight-nucleate embryo sac after three rounds of mitosis. The mature embryo sac consists of an egg apparatus (an egg and two synergids), a central cell, and three antipodal cells. -

Clematis wood has features typical of wood of vines and lianas: wide (earlywood) vessels, abundant axial parenchyma (earlywood, some species), high vessel density, low proportion of fibrous tissue in wood, wide rays composed of thin-walled cells, and abrupt origin of multiseriate rays. Superimposed on these features are expressions indicative of xeromorphy in the species of cold or dry areas: numerous narrow late wood vessels, presence of vasicentric tracheids, shorter vessel elements, and strongly marked growth rings. Wood of Xanthorhiza is like that of a (small) shrub. Wood of Delphinium, Helleborus, and Thalictrum is characteristic of herbs that become woodier: limited amounts of secondary xylem, par enchymatization of wood, partial conversion of ray areas to libriform fibers (partial raylessness). -
Summary Report on Forests of the Mataqali Nadicake Kilaka, Kubulau District, Bua, Vanua Levu
SUMMARY REPORT ON FORESTS OF THE MATAQALI NADICAKE KILAKA, KUBULAU DISTRICT, BUA, VANUA LEVU By Gunnar Keppel (Biology Department, University of the South Pacific) INTRODUCTION I was approached by Dr. David Olson of the Wildlife Conservation Society (WCS) to assess the type, status and quality of the forest in Kubulau District, Bua, Vanua Levu. I initially spent 2 days, Friday (28/10/2005) afternoon and the whole of Saturday (29/10/2005), in Kubulau district. This invitation was the result of interest by some landowning family clans (mataqali) to protect part of their land and the offer by WCS to assist in reserving part of their land for conservation purposes. On Friday I visited two forest patches (one logged about 40 years ago and another old-growth) near the coast and Saturday walking through the forests in the center of the district. Because of the scarcity of data obtained (and because the forest appeared suitable for my PhD research), I decided to return to the district for a more detailed survey of the northernmost forests of Kubulau district from Saturday (12/11/2005) to Tuesday (22/11/2005). Upon returning, I found out that the mataqali Nadicake Nadi had abandoned plans to set up a reserve and initiated steps to log their forests. Therefore, I decided to focus my research on the land of the mataqali Nadicake Kilaka only. My objectives were the following: 1) to determine the types of vegetation present 2) to produce a checklist of the flora and, through this list, identify rare and threatened species in the reserve 3) to undertake a quantitative survey of the northernmost forests (lowland tropical rain forest) by setting up 4 permanent 50 ×50m plots 4) to assess the status of the forests 5) to determine the state and suitability of the proposed reserve 6) to assess possible threats to the proposed reserve. -
Ecological Aspects of the Cretaceous Flowering Plant Radiation1
Aww. Akv. EarfA f/o««f. Sci. 799& 26. J7V-/J/ ECOLOGICAL ASPECTS OF THE CRETACEOUS FLOWERING PLANT RADIATION1 Scott L. Wing and Lisa D. Boucher Department of Paleobiology, NHB121, National Museum of Natural History, Smithsonian Institution, Washington, DC 20560; e-mail: [email protected], boucherl @ nmnh. si.edu KEY WORDS: angiosperms, Cretaceous, paleoecology, diversification, evolution ABSTRACT The first flowering plant fossils occur as rare, undiverse pollen grains in the Early Cretaceous (Valanginian-Hauterivian). Angiosperms diversified slowly during the Barremian-Aptian but rapidly during the Albian-Cenomanian. By the end of the Cretaceous, at least half of the living angiosperm orders were present, and angiosperms were greater than 70% of terrestrial plant species globally. The rapid diversification of the group, and its dominance in modern vegetation, has led to the idea that the Cretaceous radiation of angiosperms also represents their rise to vegetational dominance. Paleoecological data cast a different light on the Cretaceous radiation of an- giosperms. Analyses of sedimentary environments indicate that angiosperms not only originated in unstable habitats but remained centered there through most of the Cretaceous. Morphology of leaves, seeds, and wood is consistent with the status of most Cretaceous angiosperms as herbs to small trees with early successional strategy. The diversification of flowering plants in the Cretaceous represents the evolution of a highly speciose clade of weeds but not necessarily a major change in global vegetation. INTRODUCTION Flowering plants, or angiosperms, are presently the most dominant group of terrestrial autotrophs. They span an array of habits including very large trees, 1 The US Government has the right to retain a nonexclusive, royalty-free license in and to any copyright covering this paper. -

In this chapter, we attempt to describe the major types of vegetation cover in this vast region as they occurred in pre- Columbian times and outline the conditions that support them. Examining the large-scale phytogeographic regions characterized by each major cover type (see Fig. I), we provide basic information on geology, geological history, topography, and climate; describe variants of physiognomy (vegetation structure) and geography; discuss transitions; and examine some floristic patterns and affinities within and among these regions. -
