Leonardo Paz Deble A tribo Gnaphalieae é composta de 180-190 gêneros e cerca de 1.240 espécies, com distribuição quase cosmopolita, com maior diversidade na África do Sul, Ásia, Austrália e América do Sul (BAYER et al., 2007; DILLON; SAGASTEGUI, 1991; WARD et al., 2009). Para a América do Sul, Dillon e Sagastegui (1991) reconheceram 2 centros de diversidade: a Cordilheira dos Andes e o Sudeste do Brasil e regiões adjacentes. Tradicionalmente, Gnaphalieae foi subordinada à tribo Inuleae, sen- do reconhecida como um dos grupos de mais difícil identificação dentro da família, dadas a homogeneidade dos caracteres vegetativos e a escassa variação dos caracteres florais (CABRERA, 1961). Estudos recentes demons- traram que as Gnaphalieae encerram grupo monofilético posicionado na base da subfamília Asteroideae (ANDERBERG, 2009; ANDERBERG et al., 2005; FUNK et al., 2005). -

Thus, more studies investigating the safety of V. polyanthes aqueous extract before the use are needed. The purpose of this study was to evaluate the toxicity, cytotoxicity and genotoxicity of V. polyanthes leaves aqueous extract using the Artemia salina and Allium cepa assays. For the A. salina assay, three groups of 10 larvae were exposed to V. polyanthes leaves aqueous extract at the concentrations of 5, 10, 20, 40, and 80 mg/ml. For the A. cepa assay, 5 onion bulbs were exposed to V. polyanthes leaves aqueous extract at 10, 20, and 40 mg/ml, and then submitted to macroscopic and microscopic analysis. As result it was identified a toxicity and cytotoxicity ofV. polyanthes dependent on the extract concentration. -

Biodiversity Data Journal 3: e4507. doi: 10.3897/ BDJ.3.e4507 Abstract Campos rupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abundance, was estimated. Altogether, we registered occurrences from 161 different taxa from 114 genera and 47 families. The families with the most species were Poaceae and Asteraceae, followed by Cyperaceae. Abiotic descriptions, including soil properties such as type, acidity, nutrient or aluminum availability, cation exchange capacity, and saturation of bases, as well as the percentage of rocky outcrops and the mean inclination for each plot, are given. This dataset provides unique insights into the campo rupestre vegetation, its specific environment and the distribution of its diversity. -
Gnaphalieae-Asteraceae) of Mexico
Botanical Sciences 92 (4): 489-491, 2014 TAXONOMY AND FLORISTIC NEW COMBINATIONS IN PSEUDOGNAPHALIUM (GNAPHALIEAE-ASTERACEAE) OF MEXICO OSCAR HINOJOSA-ESPINOSA Y JOSÉ LUIS VILLASEÑOR1 Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México, México, D.F., México 1Corresponding author: [email protected] Abstract: In a broad sense, Gnaphalium L. is a heterogeneous and polyphyletic genus. Pseudognaphalium Kirp. is one of the many segregated genera from Gnaphalium which have been proposed to obtain subgroups that are better defi ned and presumably monophyletic. Although most Mexican species of Gnaphalium s.l. have been transferred to Pseudognaphalium, the combinations so far proposed do not include a few Mexican taxa that truly belong in Pseudognaphalium. In this paper, the differences between Gnaphalium s.s. and Pseudognaphalium are briefl y addressed, and the transfer of two Mexican species and three varieties from Gnaphalium to Pseudognaphalium are presented. Key Words: generic segregate, Gnaphalium, Mexican composites, taxonomy. Resumen: En sentido amplio, Gnaphalium L. es un género heterogéneo y polifi lético. Pseudognaphalium Kirp. es uno de varios géneros segregados, a partir de Gnaphalium, que se han propuesto para obtener subgrupos mejor defi nidos y presumiblemente monofi léticos. La mayoría de las especies mexicanas de Gnaphalium s.l. han sido transferidas al género Pseudognaphalium; sin embargo, las combinaciones propuestas hasta el momento no cubren algunos taxones mexicanos que pertenecen a Pseudogna- phalium. En este trabajo se explican brevemente las diferencias entre Gnaphalium s.s. y Pseudognaphalium, y se presentan las transferencias de dos especies y tres variedades mexicanas de Gnaphalium a Pseudognaphalium. Palabras clave: compuestas mexicanas, Gnaphalium, segregados genéricos, taxonomía. -

The New World is one of the centers of diversity of the tribe with 24 genera and over 100 species, most of which form a clade called the Luciliagroup with 21 genera. However, the generic classification of the Luciliagroup has been controversial with no agreement on delimitation or circumscription of genera. Especially controversial has been the taxonomic value of achenial trichomes and molecular studies have shown equivocal results so far. The major aims of this paper are to provide a nearly complete phylogeny of the Lucilia group at generic level and to discuss the evolutionary trends and taxonomic significance of achenial trichome morphology. -

Beneficial Effects of Flower-Dwelling Predators on Their Host Plant
Ecology, 85(2), 2004, pp. 446±457 q 2004 by the Ecological Society of America BENEFICIAL EFFECTS OF FLOWER-DWELLING PREDATORS ON THEIR HOST PLANT GUSTAVO Q. ROMERO1 AND JOAÄ O VASCONCELLOS-NETO Departamento de Zoologia, Instituto de Biologia, Universidade Estadual de Campinas (UNICAMP), C.P. 6109, Campinas, SP, 13083-970 Brazil Abstract. We examined the effects of the sit-and-wait spider Misumenops argenteus (Thomisidae) on the herbivore assemblage and ®tness of the perennial woody shrub Tri- chogoniopsis adenantha (Asteraceae). Because crab spiders prey on both pollinators and phytophagous insects, they can have potentially negative and positive effects on plants. In a manipulative experiment using paired plants, spiders decreased the density of sucking and some endophagous herbivores on the leaves and capitula and reduced the number of damaged achenes produced by the plants. Damaged capitula had a higher proportion of fertilized achenes in plants with spiders than without spiders, but not undamaged capitula. These results indicate that M. argenteus exerted a double positive effect on seed production in T. adenantha. The effect of M. argenteus on herbivores may be taxon speci®c and vary among years with different herbivore abundances.
