  • Verbena Bonariensis
    A Horticulture Information article from the Wisconsin Master Gardener website, posted 16 July 2004 Verbena bonariensis Clusters of small purple fl owers fl oating on long, airy stems tempting passing butterfl ies to stop for a sip is just one reason to consider adding Verbena bonairiensis, also called tall verbena or purpletop verbena, to your garden. This plant is just one of about 250 species in the genus Verbena, of which only about half a dozen are in cultivation. V. bonairiensis is native to Brazil and Ar- gentina (the specifi c name is after Buenos Aires). They were fi rst grown as a garden ornamental in 1726 by Englishmen James & William Sherard, who got the seeds from a dried specimen sent back to England from Buenos Aires. This plant is perennial in zones 7 to11 and is grown as an annual in cooler climates. It is considered a weed in many mild climates, such as California, Texas, Australia and southern Africa, where it has naturalized. Verbena bonariensis is a tall, airy plant. Purpletop verbena is an upright, clump-form- ing plant with wiry, widely branched stems. It reaches a height of 3 to 6 feet and spreads 1 to 3 feet. Unlike many other tall herbaceous plants it is unlikely to tip over. The stiff stems and branches are square and rough, like sand paper. The deep green, lance-shaped serrat- ed leaves form a mounded rosette at the base of the plant, with few on the stems. The fl ow- ers are borne in rounded clusters 2 to 3 inches across.

  • 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. For further information, see the references on the last page.

    Available online a t www.pelagiaresearchlibrary.com Pelagia Research Library Advances in Applied Science Research, 2015, 6(3):179-184 ISSN: 0976-8610 CODEN (USA): AASRFC Phylogenetic relationships among the mangrove species of Acanthaceae found in Indian Sundarban, as revealed by RAPD analysis Surya Shekhar Das 1, Swati Das (Sur) 2 and Parthadeb Ghosh* 1Department of Botany, Bolpur College, Birbhum, West Bengal, India 2Department of Botany, Nabadwip Vidyasagar College, Nadia, West Bengal, India _____________________________________________________________________________________________ ABSTRACT RAPD markers were successfully used to identify and differentiate all the five species of Acanthaceae found in the mangrove forest of Indian Sundarban, to assess the extent of interspecific genetic diversity among them, to reveal their molecular phylogeny and to throw some light on the systematic position of Avicennia. The dendrogram reveals that the five species under study exhibits an overall similarity of 60.7%. Avicennia alba and A. officinalis (cluster C1) have very close relationship between them and share a common node in the dendrogram at a 73.3% level of similarity. Avicennia marina and Acanthus ilicifolius (cluster C2) also have close relationship between them as evident by a common node in the dendrogram at 71.8% level of similarity. Acanthus volubilis showed 68.1% similarity with cluster C1 and 60.7% similarity with cluster C2. Our study also supported the view of placing Avicennia under Acanthaceae. Regarding the relative position of Avicennia within Acanthaceae, it was shown to be very close to Acanthoideae. In comparison to other species, A. marina showed most genetic variability, suggesting utilization of this species over others for breeding programme and as source material in in situ conservation programmes.

  • Studies on the Trichomes of Some Oleaceae, Structure and Ontogeny
    STUDIES ON THE TRICHOMES OF SOME OLEACEAE, STRUCTURE AND ONTOGENY B~ J. A. INAMDAR (Department of Botany, Sardar Patel Univeraity, Vallabh Vidyanagar, Gujarat) Received August 22, 1967 (Communicated by Prof. V. Puff, r.A.sc.) ABSTRACT Some twelve types of tricho~aes are described for four species of Jasminum and Nyctanthes arbor-tristis L. They fall under two main categories, the eglandular and the glandular trichomes. The systematic position of Nyctanthes seems to be quite natural in the family Oleaceae. INTRODUCTION The family Oleaceae has received considerable attention of the botanists particularly with reference to the systcmatic position of Nyctanthes and the monotypic genus Dimetra. Airy SEaw (1952) transferred these gcnera to the Verbenaceae on morphological grounds. Stant (1952) has supported Airy Shaw on anatomical grounds. Johnson (1957) in a review of the family Oleaceae opined that Nyctanthes should be excluded from Oleaceae based on the cytological findings of Taylor (1945). On the other hand the embryo- logical data (Patel, 1963; Kapil, 1967) suggests that Nyctanthes should be retained in the Oleaceae. Several workers (De Bary, 1884; Cowan, 1950, Goodspeed, 1954; Carlquist, 1958, 1959a, 1959b, 1959c, 1961; Mathur, 1961 ; Ramayya, 1962 a, 1962b, 1963) have described the structure and development of trichomes and glands in several angisoperm families. The present investi- gation was carried out to find if the trichomes ~nd glands could be of any help in settling the doubtful systematic position of Oleaceous genera. The present paper deals with the study of eglandular and glandular (glands) trichomes on the vegetative organs of four species of Jasminum, viz., J.

  • (Verbenaceae) Using Multiple Loci
    bs_bs_banner Botanical Journal of the Linnean Society, 2013, 171, 103–119. With 5 figures Investigating the evolution of Lantaneae (Verbenaceae) using multiple loci PATRICIA LU-IRVING* and RICHARD G. OLMSTEAD Department of Biology, University of Washington, Seattle, Washington 98195, USA Received 3 February 2012; revised 29 June 2012; accepted for publication 23 August 2012 Lantaneae are an example of a taxonomically problematic, widespread and recently radiated Neotropical lineage. Taxonomy in Lantaneae is difficult because of complex, overlapping patterns of shifts in morphological traits among members; monophyly of the traditional genera cannot be assumed without additional information from molecular data. We took a multi-locus approach to infer phylogenetic relationships in Lantaneae, resolving major clades among a broad representative sample that covers the morphological, taxonomic and geographical diversity of this group. Data from multiple, independent loci reveal individual gene trees that are incongruent with one another, with varying degrees of support. Without reliable, applicable methods to determine the sources of such incongru- ence and to resolve it, we present the consensus between well-supported topologies among our data sets as the best estimate of Lantaneae phylogeny to date. According to this consensus tree, fleshy fruits in Lantaneae have been derived from dry fruits at least five times; taxonomic schemes separating genera based on fruit characteristics are artificial. Lantaneae have shifted into the Neotropics from the southern temperate subtropics and have colonized Africa in at least two separate long-distance dispersal events. This study provides a first pass at a broad Lantaneae phylogeny, but two important areas remain unresolved: the position of Acantholippia relative to Aloysia; and species-level relationships in the Lantana–Lippia clade.

  • Towards Resolving Lamiales Relationships
    Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales.

    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.
