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. -

Description and Phylogenetic Position of a New Species of Nematanthus (Gesneriaceae) from Bahia, Brazil
Description and phylogenetic position of a new species of Nematanthus (Gesneriaceae) from Bahia, Brazil Alain Chautems & Mathieu Perret Abstract CHAUTEMS, A. & M. PERRET (2017). Description and phylogenetic position of a new species of Nematanthus (Gesneriaceae) from Bahia, Brazil. Candollea 72 : 351-359. In English, English abstract. DOI: http://dx.doi.org/10.15553/c2017v722a13 Nematanthus exsertus Chautems, a new species of Gesneriaceae from the state of Bahia in Brazil, is described. It is easily distinguished from other Nematanthus Schrad. species by its pendent resupinate flowers with funnel-shaped and laterally compressed corolla combined with striking exserted stamens and style. According to the phylogenetic analyses based on nuclear and plastid DNA sequences, this species belongs to a clade including the morphologically distinct Nematanthus monanthos (Vell.) Chautems and four other species with a similar flower morphology but lacking exserted stamen and style. Field photographs accompany the description. The new species is known from one locality in the municipality of Wenceslau Guimarães in the southern part of Bahia state within the “região cacaueira” [cocoa producing area]. The new species is assigned a preliminary assessment of “Vulnerable” using the IUCN Red List Categories and Criteria.

THE RE-ESTABLISHMENT OF MOUSSONIA REGEL (GESNERIACEAE) Hans Wiehler* The genus M oussonia was described by Eduard Regel in 1848, recog nized by Oersted, Walpers, Decaisne, and Hanstein, submerged by Bentham (1876) in his genus Isoloma (= Kohleria Regel), and finally treated as a separate section of Kohleria by Fritsch (1893-94). There has been no fur ther taxonomic revision of the genus Kohleria which now comprises a di verse group of more than 50 species. Kohleria belongs into the tribe Glox inieae Fritsch of the neotropical subfamily Gesnerioideae. The species are herbaceous or suffrutescent, varying in height from 15 cm to 2 m. They occur mostly at the edge of the rain forest, in clearings, by river banks, or on moist cliffs and road cuts. Most of the species have red corollas with long inflated tubes. Some showy Kohleria species and their hybrids have been in horticulture in Europe since about 1840. A number of these hybrids were produced by Regel himself. Many new species have been introduced to cultivation since around 1960. The observation of living material (especially at Cornell University), cytogenetic investigations (at Cornell University, at the Agricultural Ex periment Station in New Haven, Connecticut and at the University of Mi ami), the study of herbarium material, and field work in Central and South America have increased our knowledge of Kohleria. It can now be stated that Kohleria is another of the gesneriaceous "corolla genera" where the similarity in flower shape determined the assumed affinity of the taxa (cf. Wiehler, 1972b, 1973). Yet an increased awareness of the phenomena of pollination shows us now that similar corolla forms indicate mostly a par ticular type of pollinating agent, in this case hummingbirds. -

Flower color largely depends on the type and abundance of pigments produced in the petals, but it is still unclear whether similar color signals rely on same biosynthetic pathways and to which extent the activation of certain pathways influences the course of floral color evolution. To address these questions, we investigated the physical and chemical aspects of floral color in the Neotropical Gesnerioideae Edited by: (ca. 1,200 spp.), in which two types of anthocyanins, hydroxyanthocyanins, and Eduardo Narbona, deoxyanthocyanins, have been recorded as floral pigments.

Ela é tradicionalmente dividida em duas subfamílias: Cyrtandroideae e Gesnerioideae. Gesnerioideae é a única subfamília encontrada no Brasil. Gesnerioideae abriga a tribo Episceae, uma das mais diversas dentro da família. A tribo Episceae é caracterizada pelo hábito epífito, ovário súpero e número de cromossomos constante entre as espécies, n=9. Nematanthus é um gênero dessa tribo, endêmico do Brasil e que conta com 31 espécies. A maior diversidade é encontrada na região sudeste. No Paraná são encontradas seis espécies: N. australis, N. fissus, N. jolyanus, N. maculatus, N. tessmannii e N wettsteinnii. -
A New Formal Classification of Gesneriaceae Is Proposed
Selbyana 31(2): 68–94. 2013. ANEW FORMAL CLASSIFICATION OF GESNERIACEAE ANTON WEBER* Department of Structural and Functional Botany, Faculty of Biodiversity, University of Vienna, A-1030 Vienna, Austria. Email: [email protected] JOHN L. CLARK Department of Biological Sciences, The University of Alabama, Tuscaloosa, AL 35487, USA. MICHAEL MO¨ LLER Royal Botanic Garden Edinburgh, Edinburgh EH3 5LR, Scotland, U.K. ABSTRACT. A new formal classification of Gesneriaceae is proposed. It is the first detailed and overall classification of the family that is essentially based on molecular phylogenetic studies. Three subfamilies are recognized: Sanangoideae (monospecific with Sanango racemosum), Gesnerioideae and Didymocarpoideae. As to recent molecular data, Sanango/Sanangoideae (New World) is sister to Gesnerioideae + Didymocarpoideae. Its inclusion in the Gesneriaceae amends the traditional concept of the family and makes the family distinctly older. Subfam. Gesnerioideae (New World, if not stated otherwise with the tribes) is subdivided into five tribes: Titanotricheae (monospecific, East Asia), Napeantheae (monogeneric), Beslerieae (with two subtribes: Besleriinae and Anetanthinae), Coronanthereae (with three subtribes: Coronantherinae, Mitrariinae and Negriinae; southern hemisphere), and Gesnerieae [with five subtribes: Gesneriinae, Gloxiniinae, Columneinae (5the traditional Episcieae), Sphaerorrhizinae (5the traditional Sphaerorhizeae, monogeneric), and Ligeriinae (5the traditional Sinningieae)]. In the Didymocarpoideae (almost exclusively -

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.
