We showed that Rio Branco was an important geographical barrier, limiting the distribution of six primate genera: Cacajao, Callicebus, Cebus to the west and Pithecia, Saguinus, Sapajus to the east. The role of this river as a vicariant agent however, was less clear. For example, Chiropotes sagulata on the left bank of the Rio Branco formed a clade with C. chiropotes from the Amazonas Department of Venezuela, north of Rio Branco headwaters, with C. israelita on the right bank of the Rio Branco as the sister taxon to C. chi- ropotes + C. sagulata. Although we showed that the formation of the Rio Negro was important in driving diversification in some of our studied taxa, future studies including more extensive sampling of markers across the genome would help determine what processes contributed to the evolutionary history of the remaining primate genera.

Graphical Abstract Abstract. Mansoa alliacea is a native plant from Mansoa alliacea Amazonian basin and has great ancestral value for the local communities. M. alliacea is part of the traditional medicine for healers and shamans and has multiple uses due to the presence of several chemical constituents with important pharmacological properties. Plant derivatives are used as: antiseptic, diuretic, analgesic, antipyretic. Folk medicine is also related to the treatment of many diseases such as: reduction of blood pressure, against atherosclerosis, arthritis and rheumatism. Researches have also proven an appreciable antioxidant property, which revalue it for cosmetic purposes. Chemical composition of plant derivatives includes as main Traditional medicine compounds: diallyl disulphide, diallyl Magical and ritual uses Cold, fever trisulphide, alliin, allicin, propylallyl, divinyl Rheumatism Food, spice sulfide, diallyl sulfide, dimethyl sulfide, Antimalarial Muscle pain daucosterol, beta-sitosterol, fucosterol, Biological activities stigmasterol, iridoides and isothiocyanates, Antioxidant Antifungal naphthoquinones, alkaloids, saponins, flavones.

    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.

  • Anatomy of Flowering Plants
    This page intentionally left blank Anatomy of Flowering Plants Understanding plant anatomy is not only fundamental to the study of plant systematics and palaeobotany, but is also an essential part of evolutionary biology, physiology, ecology, and the rapidly expanding science of developmental genetics. In the third edition of her successful textbook, Paula Rudall provides a comprehensive yet succinct introduction to the anatomy of flowering plants. Thoroughly revised and updated throughout, the book covers all aspects of comparative plant structure and development, arranged in a series of chapters on the stem, root, leaf, flower, seed and fruit. Internal structures are described using magnification aids from the simple hand-lens to the electron microscope. Numerous references to recent topical literature are included, and new illustrations reflect a wide range of flowering plant species. The phylogenetic context of plant names has also been updated as a result of improved understanding of the relationships among flowering plants. This clearly written text is ideal for students studying a wide range of courses in botany and plant science, and is also an excellent resource for professional and amateur horticulturists. Paula Rudall is Head of Micromorphology(Plant Anatomy and Palynology) at the Royal Botanic Gardens, Kew. She has published more than 150 peer-reviewed papers, using comparative floral and pollen morphology, anatomy and embryology to explore evolution across seed plants.
