Filogenia, Biogeografia E Conservação Do Gênero Trichocline Cass. (Asteraceae, Mutisieae)
1 UNIVERSIDADE FEDERAL DO RIO GRANDE DO SUL INSTITUTO DE BIOCIÊNCIAS DEPARTAMENTO DE BOTÂNICA PROGRAMA DE PÓS-GRADUAÇÃO EM BOTÂNICA Doutorando: Eduardo Pasini Orientadora:Dra. Sílvia T. S. Miotto Co-orientadora: Dra. Tatiana Teixeira de Souza-Chies Colaboradora: Drª. Liliana Katinas Filogenia, biogeografia e conservação do gênero Trichocline Cass. (Asteraceae, Mutisieae) 1. Introdução 1.1. Abordagem sistemática Asteraceae é uma das principais famílias botânicas dentre as angiospermas por apresentar o maior número de espécies descritas e aceitas até o momento. Estimativas mostram que apesar das 24.000 espécies já descritas, pode haver um total de 30.000 em 1600 a 1700 gêneros distribuídos ao redor do globo, com exceção da Antártida (Funk et al. 2009). As relações filogenéticas dentro da família estão cada vez mais claras, devido a trabalhos de biologia molecular (e.g. Jansen et al. 1991; Karis et al. 1992; Karis 1993; Kim & Jansen 1995; Kim et al. 2005; Panero & Funk 2008). Os resultados de tais trabalhos apontam uma natural dicotomia representada por dois grupos monofiléticos, a subfamília Barnadesioideae (Bremer & Jansen 1992), como o grupo mais cedo divergente, e o restante das Asteraceae. Atualmente, reconhece-se 12 subfamílias e 43 tribos (Funk et al. 2009). A subfamília Mutisioideae representa grandes desafios na elucidação das relações filogenéticas da família, uma vez que é parafilética e juntamente com a subfamília Barnadesioideae constitui o clado-irmão dos demais agrupamentos (Funk et al. 2009). Atualmente, são aceitas duas classificações principais da subfamília, uma compreendida por estudos de natureza morfológica e 2 outra sustentada por evidências filogenéticas. O primeiro conceito (Mutisioideae sensu lato) compreende 74 gêneros e 865 espécies, distribuídas em três tribos, Mutisieae, Nassauvieae e Stifftieae (Katinas et al. -

Literature Cited
Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes. -

Relatively few cases of abnormalities in Gerbera jamesonii of greenhouse cultivation have received attention in the literature. The cases reported are scattered over a period and no detailed historical study has apparently been made nor listed collectively. Some extra efforts regarding enhancement of yield leads to some physiological disorders. Also, insect attack, edaphic and uncontrolled environmental factors may destroy the quality and vigour of plant exhibiting abnormalities. This Paper describes abnormalities observed in commercial floriculture plots during study period. Key words: Gerbera jamesonii, Phyllody, Greenhouse, Vegetative abnormality, Reproductive abnormality Gerbera (Gerbera jamesonii Bolus ex Hook) is the among varieties.

The combination of its diagnostic characters including discoid homogamous capitula, alveolate epaleate receptacles, and deeply trifid leaves, is not found in any other species of South American Astereae. An ITS phylogenic analysis placed Kieslingia chilensis within subtribe Hinterhuberinae, and sister to the genus Guynesomia, also endemic to Chile. The morphological characteristics of Kieslingia chilensis are compared and contrasted to sister taxa as identified by the molecular phylogenetic studies and the environmental features of the area where the species is found are discussed. A key to distinguish Kieslingia from other Astereae genera of northern Chile is given. -

Everywhere but Antarctica: Using a supertree to understand the diversity and distribution of the Compositae. Biol. Skr. 55: 343-374. ISSN 0366-3612. ISBN 87-7304-304-4. One of every 10 flowering plant species is in the family Compositae. With ca. 24,000-30,000 species in 1600-1700 genera and a distribution that is global except for Antarctica, it is the most diverse of all plant families. Although clearly mouophyletic, there is a great deal of diversity among the members: habit varies from annual and perennial herbs to shrubs, vines, or trees, and species grow in nearly every type of habitat from lowland forests to the high alpine fell fields, though they are most common in open areas. Some are well-known weeds, but most species have restricted distributions, and members of this family are often important components of 'at risk' habitats as in the Cape Floral Kingdom or the Hawaiian Islands. The sub-familial classification and ideas about major patterns of evolution and diversification within the family remained largely unchanged from Beutham through Cronquist. Recently obtained data, both morphologi- cal and molecular, have allowed us to examine the distribution and evolution of the family in a way that was never before possible. -
