Christian Feuillet Department of Botany, MRC-166 Smithsonian Institution P.O CHECKLIST OF THE PLANTS OF THE GUIANA SHIELD 1. AN UPDATE TO THE ANGIOSPERMS Christian Feuillet Department of Botany, MRC-166 Smithsonian Institution P.O. Box 37012 Washington, D.C. 20013-7012, U.S.A. [email protected] ABSTRACT An update to the Checklist of the Plants of the Guiana Shield is proposed. It comprises more than 700 additions, corrections, and synonymies for the Angiosperms. Two new combinations are made in the Rubiaceae: Appunia longipedunculata and Appunia peduncularis. RÉSUMÉ Une mise à jour de la Checklist of the Plants of the Guiana Shield est offerte. Elle comprend plus de 700 additions, corrections et synony- mies pour les Angiospermes. Deux combinaisons nouvelles sont faites dans les Rubiaceae: Appunia longipedunculata et Appunia peduncularis. The flora of the Guiana Shield is the object of strong interest that fostered various international programs as evidenced and enhanced by the publication of the Flora of the Guianas (Görts-van Rijn & Janssen-Jacobs 1985–present; in progress), the Flora of the Venezuelan Guayana (Berry et al. 1995–2005), and the Guide to the vascular plants of central French Guiana (Mori et al. 1997 and 2002), as well as by the large specimen- based database at the Department of Botany of the Smithsonian Institution. There was a need to compare results and therefore for conformity of the taxonomy. The Checklist of the Plants of the Guiana Shield (Funk et al. 2007) was the tool to fill that need. The phase of data gathering for theChecklist was completed in 2005. Since then, many papers have been published on the flora of the region adding several species, changing their generic placement, or refuting their presence in the Guiana Shield. Furthermore, due to the widely scattered literature, some taxa were overlooked. Hence many additions, deletions, and corrections must be made before an updated version of the Checklist can be offered for consultation on-line. This paper presents 719 modifications needed for the Angiosperms and gathers in one place the references for the new species. The results are presented in the Appendix. For the Angiosperms, 211 names are added to the checklist and 159 are placed in synonymy or rejected. Therefore, there is a gain of 52 and the total number of accepted subgeneric names is now 14,784. A later paper will update the ferns and allied groups. The Checklist (Funk et al. 2007) can be down- loaded from http://botany.si.edu/bdg/plants.html along with this update and relevant pdf files. If you know of taxa that should have been added, edited, or deleted, please let me know. A pp ENDIX : MODIFICATIONS The families are presented in alphabetical order under the family name used in the Checklist (Funk et al. 2007). The names of the families are followed by the pages where they can be found in the Checklist. Names of species and infraspecific taxa to be added are in bold, followed by the symbols of the regions (AM = Amazonas; BO = Bolivar; DA = Delta Amacuro; FG = French Guiana; GU = Guyana; SU = Surinam). Names of species in italics are to be edited or deleted. As in the checklist, the family chapters are followed when needed by two paragraphs: “Synonyms and misidentifications” and “References.” Occasionally a note clarifies a problem.

C., Colombia; [email protected] (autor corresponsal). Abstract. Giraldo-Cañas, D. 2021. Malpighiaceae from Colombia: Patterns of distribution, richness, endemism, and phylogenetic diversity. Darwiniana, nueva serie 9(1): 39-54. Malpighiaceae constitutes a family of 77 genera and ca. 1300 species, distributed in tropical and subtropical regions of both hemispheres. They are mainly diversified in the American continent and distributed in a wide range of habitats and altitudinal gradients. For this reason, this family can be a model plant group to ecological and biogeographical analyses, as well as evolutive studies. In this context, an analysis of distribution, richness, endemism and phylogenetic diversity of Malpighiaceae in natural regions and their altitudinal gradients was undertaken. Malpighiaceae are represented in Colombia by 34 genera and 246 species (19.1% of endemism). Thus, Colombia and Brazil (44 genera, 584 species, 61% of endemism) are the two richest countries on species of this family. The highest species richness and endemism in Colombia is found in the lowlands (0-500 m a.s.l.: 212 species, 28 endemics); only ten species are distributed on highlands (2500-3200 m a.s.l.). Of the Malpighiaceae species in Colombia, Heteropterys leona and Stigmaphyllon bannisterioides have a disjunct amphi-Atlantic distribution, and six other species show intra-American disjunctions.

  • Rubiaceae), and the Description of the New Species Galianthe Vasquezii from Peru and Colombia
    Morphological and molecular data confirm the transfer of homostylous species in the typically distylous genus Galianthe (Rubiaceae), and the description of the new species Galianthe vasquezii from Peru and Colombia Javier Elias Florentín1, Andrea Alejandra Cabaña Fader1, Roberto Manuel Salas1, Steven Janssens2, Steven Dessein2 and Elsa Leonor Cabral1 1 Herbarium CTES, Instituto de Botánica del Nordeste, Corrientes, Argentina 2 Plant systematic, Botanic Garden Meise, Meise, Belgium ABSTRACT Galianthe (Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, Galianthe subgen. Galianthe, with 39 species and Galianthe subgen. Ebelia, with 11 species. The diagnostic features of the genus are: usually erect habit with xylopodium, distylous flowers arranged in lax thyrsoid inflorescences, bifid stigmas, 2-carpellate and longitudinally dehiscent fruits, with dehiscent valves or indehiscent mericarps, plump seeds or complanate with a wing-like strophiole, and pollen with double reticulum, rarely with a simple reticulum. This study focused on two species that were originally described under Diodia due to the occurrence of fruits indehiscent mericarps: Diodia palustris and D. spicata. In the present study, classical taxonomy is combined with molecular analyses. As a result, we propose that both Diodia species belong to Galianthe subgen. Ebelia. The molecular position within Galianthe, based on ITS and ETS sequences, has been supported by the following morphological Submitted 10 June 2017 characters: thyrsoid, spiciform or cymoidal inflorescences, bifid stigmas, pollen grains Accepted 19 October 2017 with a double reticulum, and indehiscent mericarps. However, both species, unlike the Published 23 November 2017 remainder of the genus Galianthe, have homostylous flowers, so the presence of this Corresponding author type of flower significantly modifies the generic concept.

Radiation of this group occurred in all biomes of tropical America and was accompanied by extensive phenotypic and ecological diversification. Here we performed phylogenetic analyses using DNA sequences from three plastid loci to reconstruct the evolutionary history of Gesnerioideae and to investigate its relationship with other lineages of Gesneriaceae and Lamiales. Our molecular data confirm the inclusion of the South Pacific Coronanthereae and the Old World (OW) monotypic genus Titanotrichum in Gesnerioideae and the sister-group relationship of this subfamily to the rest of the OW Gesneriaceae. Calceolariaceae and the NW genera Peltanthera and Sanango appeared successively sister to Gesneriaceae, whereas Cubitanthus, which has been previously assigned to Gesneriaceae, is shown to be related to Linderniaceae. Based on molecular dating and biogeographical reconstruction analyses, we suggest that ancestors of Gesneriaceae originated in South America during the Late Cretaceous.

Naturhist. Mus. Wien, B 120 59–140 Wien, Jänner 2018 Synopsis and typification of Mexican and Central American Palicourea (Rubiaceae: Palicoureeae), part I: The entomophilous species A. Berger* Abstract The prominent but complex genus Psychotria (Rubiaceae: Psychotrieae) is one of the largest genera of flow- ering plants and its generic circumscription has been controversial for a long time. Recent DNA-phyloge- netic studies in combination with a re-evaluation of morphological characters have led to a disintegration process that peaked in the segregation of hundreds of species into various genera within the new sister tribe Palicoureeae. These studies have also shown that species of Psychotria subg. Heteropsychotria are nested within Palicourea, which was traditionally separated by showing an ornithophilous (vs. entomophilous) pol- lination syndrome. In order to render the genera Palicourea and Psychotria monophyletic groups, all species of subg. Heteropsychotria have to be transferred to Palicourea and various authors and publications have provided some of the necessary combinations. In the course of ongoing research on biotic interactions and chemodiversity of the latter genus, the need for a comprehensive and modern compilation of species of Pali­ courea in its new circumscription became apparent. As first step towards such a synopsis, the entomophilous Mexican and Central American species (the traditional concept of Psychotria subg.

Pollen tube growth rates (PTGRs) of angiosperms are exceptionally rapid, a pattern 25 attributed to more effective haploid selection under stronger pollen competition. Paradoxically, 26 whole genome duplication (WGD) has been common in angiosperms but rare in gymnosperms.

Koenig, Biology and Phylogeny of Tropical Birds, Adenauerallee 160, 53113 Bonn, Germany. Resumen. – Una nueva especie de Eriocnemis (Trochilidae) del suroeste de Colombia. – Una nueva especie de colibrí, el Zamarrito del Pinche (Eriocnemis isabellae, sp. nov.), es descrita de la Serranía del Pinche, un macizo aislado e inexplorado localizado en el Departamento del Cauca en el suroeste de Colombia (02°16’04.18”N, 77°21’26.41”W, 2800 m s.n.m.). Esta especie representa un nuevo miembro distincto del género Eriocnemis y habita los bosques templados y nublados de la Serranía. Aunque se puede identificar fácilmente como un miembro del género Eriocnemis por sus zamarros blancos, el azul violeta en las infracaudales de la cola y la cola azul negra bifurcada, se diferencia ampliamente de la mayoría de las especies de su género en tener la cara, corona y nuca de color negro con visos amarillosos verde oliva. Además, tiene una gorguera bicolor iridiscente distincta, azul violeta y verde. Este nuevo taxón comparte algunas características con otros de su género (i.e., E. vestitus, E. nigrivestis) y esta ecológicamente asociado a bosques enanos ocupando un pequeño rango en pendientes pronunciadas a lo largo de filos montañosos.
