  • 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.

The triad all have floral venation similar to red, tubular-flowered species of Just icia, though they differ from most Justicia in their tricolporate pollen with distinct pseudocolpi. In pollen and anther characters they are similar to Anisacanthus and Carlowrightia, but they differ from these in corolla vascularization and anther presentation and from Carlowrightia in corolla size. As the three taxa do not appear to represent a monophyletic group, and as Stearn has placed taxa with similar pollen into what has become a holding genus, Justicia, we include these in Justicia by default until further studies can decipher relat ionships within the genus.

  • Open As a Single Document
    From Medieval Park to Modern Arboretum: The Arnold Arboretum and its Historic Background In celebrating a hundred years of growth of an institution such as the Arnold Arboretum of Harvard University primarily devoted to the cultivation and study of trees, it is natural even if trite to compare such an institution to a tree itself, above all to such an impressive sturdy long-lived tree as an oak, and then to seek analogies of development, elaborating the simile in a manner worthy of an old New England preacher somewhat like Father Mapple of Melville’s Moby Dick. Thus tree-like, one might say, the Arnold Arboretum thrusts its roots deep into good hard earth such as solid Boston and Cambridge banking accounts provide, pushes out its dollar-fed branches slowly but strongly in many directions to resist wind and tem- pest, i.e. depressions, slumps, inflations, lawsuits, hurricanes and the like, towers massively above other institutions of more recent sprouting and displays its abundant foliage, both actual and figurative, for all to admire. Such eloquent comparisons can, however, be carried too far. The Arnold Arboretum’s publi- cations appreciated by botanists the world over may indeed be likened to the fruit of our imagined tree but, unfortunately for this nice simile, the fruit of an oak is most appreciated by crows and swine! Nevertheless, the simile has its value. An individual oak, while possessing its own particular characteristics as an indi- vidual, grows mainly the way it does because of events which happened even before it started as an acorn, sometimes very long before that.

Inflo- rescences terminal or axillary spikes, racemes, panicles, or dense clusters, rarely of solitary flowers; bracts 1 per flower or dichasial cluster, large and brightly colored or minute and green, sometimes becoming spinose; bracteoles present or rarely absent, usually 2 per flower. Flowers sessile or pedicellate, bisexual, zygomorphic to subactinomorphic. Calyx synsepalous (at least basally), usually 4- or 5-lobed, rarely (Thunbergia) reduced to an entire cupular ring or 10–20-lobed. Corolla sympetalous, sometimes resupinate 180º by twisting of corolla tube; tube cylindric or funnelform; limb subactinomorphic (i.e., subequally 5-lobed) or zygomorphic (either 2- lipped with upper lip subentire to 2-lobed and lower lip 3-lobed, or rarely 1-lipped with 3 lobes); lobes ascending or descending cochlear, quincuncial, contorted, or open in bud. Stamens epipetalous, included in or exserted from corolla tube, 2 or 4 and didyna- mous; filaments distinct, connate in pairs, or monadelphous basally via a sheath (Strobilanthes); anthers with 1 or 2 thecae; thecae parallel to perpendicular, equally inserted to superposed, spherical to linear, base muticous or spurred, usually longitudinally dehis- cent; staminodes 0–3, consisting of minute projections or sterile filaments.

All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales.

  • New Species and Combinations in Acanthaceae from Somalia
    Willdenowia 36 – 2006 751 MIKAEL HEDRÉN New species and combinations in Acanthaceae from Somalia Abstract Hedrén, M.: New species and combinations in Acanthaceae from Somalia. – Willdenowia 36: 751-759. – ISSN 0511-9618; © 2006 BGBM Berlin-Dahlem. doi:10.3372/wi.36.36210 (available via http://dx.doi.org/) Six species from Somalia, Barleria albomarginata, B. dentata, B. glaucobracteata, B. ilicifolia, Hypoestes cinerea and Justicia carnosa, are described as new to science, J. arenaria is proposed as a new name for J. ovalifolia var. psammophila and the new combination B. brevispina is proposed for B. linearifolia var. brevispina. Key words: Barleria, Hypoestes, Justicia, taxonomy, Horn of Africa region. During revisional work in various genera of Acanthaceae for the Flora of Somalia project, six previously undescribed species were encountered. They are formally published here, along with a new name and a new combination at species level for taxa previously treated as varieties. The species are arranged in the same sequence as they have in the Flora (Hedrén in Thulin 2006). Justicia arenaria Hedrén, nom. & stat. nov. ≡ Justicia ovalifolia var. psammophila Fiori in Boll. Soc. Bot. Ital. 1915: 57. 1915. Holotype: Somalia, between Mogadishu and Gezira by the sea, 25.5.1913, Paoli 61 (FT). Justicia arenaria is known only from coastal sand dunes at 10-40 m altitude in southern Somalia. It is closely related to the widespread and variable J. flava (Vahl) Vahl, but differs by its almost orbicular, thick and somewhat succulent leaves. Progeny from Hedberg 7143 (UPS) cultivated in the Botanical Garden of Uppsala University also developed suborbicular, thick and succulent leaves, showing that these characters are genetically determined.

  • Checklist of the Washington Baltimore Area
    Annotated Checklist of the Vascular Plants of the Washington - Baltimore Area Part I Ferns, Fern Allies, Gymnosperms, and Dicotyledons by Stanwyn G. Shetler and Sylvia Stone Orli Department of Botany National Museum of Natural History 2000 Department of Botany, National Museum of Natural History Smithsonian Institution, Washington, DC 20560-0166 ii iii PREFACE The better part of a century has elapsed since A. S. Hitchcock and Paul C. Standley published their succinct manual in 1919 for the identification of the vascular flora in the Washington, DC, area. A comparable new manual has long been needed. As with their work, such a manual should be produced through a collaborative effort of the region’s botanists and other experts. The Annotated Checklist is offered as a first step, in the hope that it will spark and facilitate that effort. In preparing this checklist, Shetler has been responsible for the taxonomy and nomenclature and Orli for the database. We have chosen to distribute the first part in preliminary form, so that it can be used, criticized, and revised while it is current and the second part (Monocotyledons) is still in progress. Additions, corrections, and comments are welcome. We hope that our checklist will stimulate a new wave of fieldwork to check on the current status of the local flora relative to what is reported here. When Part II is finished, the two parts will be combined into a single publication. We also maintain a Web site for the Flora of the Washington-Baltimore Area, and the database can be searched there (http://www.nmnh.si.edu/botany/projects/dcflora).

  • Editorial This Autumn We Have Been Celebrating the Bicentenary of the Birth of Charles Lyell (B
    THE LINNEAN I Editorial This autumn we have been celebrating the bicentenary of the birth of Charles Lyell (b. 14 November 1797) whose greatest contribution to the advancement of science was his Principles of Geology which first appeared during 1830-33 and subsequently went through 13 revisions. Although this work inspired both Darwin and Hooker and furnished Wallace “with the main features of the succession of species in time” - Lye11 could never bring himself to accept “the descent of man from the brutes”. Picture taken by Dr R. Spearman on the occasion ofthe Lyell Bicentenary lecture 31 July 1997. Left to right: G. Prance, W. Stearn CBE. W. Challoner, Jim Secord, S. Berry, M. Claridge, J. Hawkes (two extant PPLs missing. A. Cave & B. Gardiner). Lyell entered the great debate on man’s origins in 1863 with his book entitled Geological Evidences a5 to the Antiquity of Man, coincidentally the same year that T. H. Huxley published his work on the Zoological Evidence as to Man’s Place in Nature. Huxley’s oook brought him notoriety whereas Darwin was somewhat distressed to find that Lyell’s book gave him no stronger support of the mutability of species than a sentence beginning “If it should be rendered highly probable that species change by variation and natural selection....”. Darwin further confided ( 1863) to Hooker 2 THE LINNEAN “I must say how much disappointed I am that he hasn’t spoken out on species, still less on man.. ... The whole certainly struck me as a compilation, but of the highest quality, for when possible the facts have been verified on the spot, making it almost an original work.

Woods of Acanthaceae are characterized by relatively narrow vessels with simple perforation plates and alternate lateral wall pitting, septate libriform fibers, scanty vasicentric axial parenchyma, rays both multiseriate and uniseriate, erect ray cells abundant in rays (some species rayless or near-rayless), numerous small crystals or cystoliths in ray cells in a few genera (first documented reports of both characters in woods of Acanthaceae), and nonstoried structure. This constellation of features is very closely matched by woods ofGesneriaceae, Scrophulariaceae, Pedaliaceae, Martyniaceae, Bignoniaceae, and Myoporaceae (families listed in order ofdecreasing resemblance). Narrowness ofvessels in tropical Acanthaceae appears related to understory ecology. A few species in warm and seasonally dry areas have narrow, short vessel elements numerous per unit transection.
