    A new species of Oxalis from Santa Cruz, Argentina is described. The new species, Oxalis morronei, belongs to O. section Palmatifoliae because of its general morphology and distribution, but differs from the other species included in that section by having square leaflets with the apices deeply emarginate, the bases slightly cordate and its margin wavy and ciliate. The new species is illustrated and affinities with other members of O. section Palmatifoliae are herein explained.Fil: López, Alicia. Consejo Nacional de Investigaciones Científicas y Técnicas.

    In the present work a revision of tribe Verbeneae for Peru is presented, descriptions and illustrations for each taxa are presented. In this country this tribe is represented by 16 taxa: four Glandularia species, five Junellia species, one Mulguraea species and four Verbena species and two varieties; six of these taxa are endemic to Peru. Three new combinations are presented: Glandularia cuneifolia, Junellia clavata and Verbena glabrata var. hayekii. Nine new synonyms are proposed, lectotypes are designated for Verbena cuneifolia, Verbena clavata and Verbena villifolia, and an epitype is designated for Verbena pogostoma.Fil: O'Leary, Nataly Cristina.

    A taxonomical and nomenclatural revision of genus Glandularia from Chile is here presented. The genus is represented by 12 species and one variety, eight of these taxa are endemic to Chile. Species are distributed from the most septentrional area of the territory, Arica and Parinacota region, towards Los Lagos region, southwards. However, the highest species diversity is found in the central regions of Coquimbo, Valparaíso and Metropolitana. Each one of the 12 species of Glandularia is here described and illustrated. Furthermore, 14 new synonyms and three new combinations are proposed: Glandularia landbecki, G. multiglandulosa, and G. ribifolia; 15 lectotypes are designated for: Erinus laciniatus, Verbena bella, V. berteroi, V. corymbosa, V. foetida, V. gynobasis, V. gynobasis var. strigosa, V. landbeckii, V. lipozygioides, V. multiglandulosa, V. porrigens, V. ribifolia, V. sulphurea var. fuscorubra, V. sulphurea var. pedunculata, and V. trachea; and one neotype is suggested for Verbena paulseni.Se presenta una revisión taxonómica y nomenclatural del género Glandularia para Chile.

    Verbena L. (Verbenaceae) comprende 44 especies, de distribucio´n predominantemente americana, con dos especies distribuidas en a´reas ca´lido-templadas de ambos hemisferios: V. officinalis L. y V. supina L. Las especies sudamericanas son morfolo´gicamente diferentes de las norteamericanas por lo cual se las ubica en dos series: Verbena ser. Pachystachyae Schauer y serie Verbena respectivamente. En el presente tratamiento se describen los taxones de Verbena ser. Verbena; esta serie comprende 26 especies divididas en tres grupos informales: Verbena, Hastatae y Bracteosae. Se proporcionan descripciones detalladas de todos los taxones, claves para identificarlos, ilustraciones, una sinonimia actualizada con 56 nuevos sino´nimos (ve´ase Ape´ndice 3), y se discuten relaciones entre taxones afines. Se introducen dos nuevas combinaciones: Verbena gracilescens (Cham.) Herter var. swiftiana (Moldenke) N. O’Leary y V. simplex Lehm. var. orcuttiana (L. M. Perry) N. O’Leary; nueve lectotipificaciones: V. bracteata Lag. & Rodr., V. bracteosa Michx. var. brevibracteata A.

(Verbenaceae) is represented by 44 species, mainly distributed in America, with two species distributed in temperate regions from both hemispheres: V. officinalis L. and V. supina L. South American species are morphologically different from North American species and are placed in two separate series: Verbena ser. Pachystachyae Schauer and series Verbena, respectively. In the present treatment, Verbena ser. Verbena taxa are described. This series includes 26 species, placed in three informal groups: Verbena, Hastatae, and Bracteosae. Detailed morphological descriptions are given for each taxon, as well as keys for their identification, illustrations, actualized synonymy with 56 new synonymized species (Appendix 3), and discussions of relationships between closely related taxa.

    A molecular phylogeny and classification of Verbenaceae

    Get PDF
    Premise of the study: Verbenaceae consist of trees, shrubs, lianas, and herbs distributed primarily in Latin America, where they occur in a wide array of ecosystems. A second center of diversity exists in Africa. Competing morphology-based classifications that rely on different traits conflict in significant ways. A broad phylogenetic study was undertaken to assess those classifications and to examine the historical geography of the family. Methods: Analysis of seven chloroplast DNA regions for 109 species, representing all genera except one monotypic genus, provide inference into evolutionary relationships in Verbenaceae. Key results: The phylogeny shows that none of the traditional classifications reflect phylogenetic relationships very well. Eight clades are recognized as tribes (Casselieae, Citharexyleae, Duranteae, Lantaneae, Neospartoneae trib. nov., Petreeae, Priveae, and Verbeneae). Two genera, Dipyrena and Rhaphithamnus, remain unplaced in these larger clades. Petreeae, which consist of Neotropical lianas, are sister to the rest of the family. Lantaneae and Verbeneae together form a derived clade that comprises approximately two-thirds of the species in Verbenaceae. Conclusions: We present a new tribal classification, including one new tribe, Neospartoneae trib. nov., to accommodate three small genera of Argentine species (Diostea, Neosparton, and Lampaya). Phylogenetic inference suggests a South American origin for Verbenaceae, with approximately six colonization events having given rise to the Old World species.Fil: Marx, Hannah E..
