Its mission is to build a global network for plant conservation. BGCI is an independent organization registered in the United Kingdom as a charity (Charity Reg No 1098834) and a company limited by guarantee, No 4673175. BGCI is a tax-exempt (501(c)(3) non-profit organization in the USA and in Russia. Opinions expressed in this publication do not necessarily reflect the views of the Boards or staff of BGCI or of its members BGjournal replaces BGCNews and is published twice a year. BGjournal has been given a new name as the news section of BGCNews and Roots (Botanic Gardens Conservation International Education Review) is now contained in Cuttings which is published quarterly.

  • Bignoniaceae)
    Systematic Botany (2007), 32(3): pp. 660–670 # Copyright 2007 by the American Society of Plant Taxonomists Taxonomic Revisions in the Polyphyletic Genus Tabebuia s. l. (Bignoniaceae) SUSAN O. GROSE1 and R. G. OLMSTEAD Department of Biology, University of Washington, Box 355325, Seattle, Washington 98195 U.S.A. 1Author for correspondence ([email protected]) Communicating Editor: James F. Smith ABSTRACT. Recent molecular studies have shown Tabebuia to be polyphyletic, thus necessitating taxonomic revision. These revisions are made here by resurrecting two genera to contain segregate clades of Tabebuia. Roseodendron Miranda consists of the two species with spathaceous calices of similar texture to the corolla. Handroanthus Mattos comprises the principally yellow flowered species with an indumentum of hairs covering the leaves and calyx. The species of Handroanthus are also characterized by having extremely dense wood containing copious quantities of lapachol. Tabebuia is restricted to those species with white to red or rarely yellow flowers and having an indumentum of stalked or sessile lepidote scales. The following new combinations are published: Handroanthus arianeae (A. H. Gentry) S. Grose, H. billbergii (Bur. & K. Schum). S. Grose subsp. billbergii, H. billbergii subsp. ampla (A. H. Gentry) S. Grose, H. botelhensis (A. H. Gentry) S. Grose, H. bureavii (Sandwith) S. Grose, H. catarinensis (A. H. Gentry) S. Grose, H. chrysanthus (Jacq.) S.

Abstract Frankia strains induce the formation of nitrogen-fixing nodules on roots of actinorhizal plants. Phylogenetically, Frankia strains can be grouped in four clusters. The earliest divergent cluster, cluster-2, has a particularly wide host range. The analysis of cluster-2 strains has been hampered by the fact that with two exceptions, they could never be cultured. In this study, 12 Frankia-enriched meta- genomes of Frankia cluster-2 strains or strain assemblages were sequenced based on seven inoculum sources. Sequences obtained via DNA isolated from whole nodules were compared with those of DNA isolated from fractionated preparations enhanced in the Frankia symbiotic structures.

The biology and ecology of S. hermaphrodita are still poorly understood and although few studies have been performed to determine the factors that contribute to the species rarity, it is considered threatened potentially due to the loss of habitat caused by exotic European Common reed (Phragmites australis subsp.

The new species differs from the other species of Amphitecna by the combination of cauliflorous inflorescences, larger flowers, buds rounded at apex, and globose-ellipsoid rather than acuminate fruits. A key to the Mexican species of Amphitecna is presented.

    Lamiales – Synoptical classification vers. 2.6.2 (in prog.) Updated: 12 April, 2016 A Synoptical Classification of the Lamiales Version 2.6.2 (This is a working document) Compiled by Richard Olmstead With the help of: D. Albach, P. Beardsley, D. Bedigian, B. Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. 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. For further information on the project and to provide information for future versions, please contact R. Olmstead via email at [email protected], or by regular mail at: Department of Biology, Box 355325, University of Washington, Seattle WA 98195, USA.
