| The goal of the present study was to identify plant species used as food source, the floral resources utilized, and the insects that visit flowers in a grassland community in southern Brazil. The study was carried out in an area of one hectare, located in a grassland formation in the Parque Estadual de Itapuã, State of Rio Grande do Sul, Brazil. The flowering pattern was seasonal, and richness and abundance of insects was higher during the period of high resource availability. Flowers of 106 species of angiosperms (73 genera and 34 families) were used as source of floral resources for 219 species (2,767 specimens) of insects. A total of 91.5% of plant species were visited by bees, 53.8% by flies, 34.9% by wasps, 22.6% by butterflies, and 12.3% by beetles.... |

| ABSTRACT Mimosa baptistae is a new species presenting stalked glandular trichomes that give it a glutinous appearance, mainly with respect to the leaflets. Furthermore, it is an aculeate species, with multijugate leaves, white stamens, and fruits also covered by glandular trichomes. A herbaria survey and fieldwork only recorded this species as occurring on sandstone outcrops of the city Caçapava do Sul, Brazil. The species may be confused with other species of Mimosa sect. Batocaulon ser. Stipellares such as M. bifurca, M. sobralii and M. lepidota. However, features such as absence/presence of aculei, stamens color, habitat, and flower features are useful for distinguishing them from the new species. Here, we provide notes on morphology, geographic... |

| ABSTRACT Most studies concerning climbing plants have focused on lianas, forest ecosystems, and tropical regions. Thus, the majority of existing information is not relevant to all climbing plants (lianas and vines) or all ecoregions of the world (forested and non-forested). We provide an update on floristic and distributional data available for climbing plants in Rio Grande do Sul, Brazil’s southernmost state, which is located within subtropical and temperate zones and includes a variety of forest and non-forest vegetation types. A total of 448 climbing plant species were confirmed and documented by voucher specimens, revealing a diversity similar to that registered for trees in the state (533). The significant contribution of climbing species to the... |

| O trabalho trata do estudo taxonômico do gênero Monnina na Região Sul do Brasil. A metodologia apresentou uma revisão bibliográfica e de herbários nacionais e internacionais, coletas nos Estados do Paraná, Santa Catarina e Rio Grande do Sul, bem como observações das espécies em seus diferentes ambientes de ocorrência. Foram reconhecidas nove espécies para a Região Sul do Brasil: Monnina cardiocarpa A. St.-Hil. & Moq., M. cuneata A. St.-Hil. & Moq., M. dictyocarpa Griseb., M. itapoanensis Vianna & Marques, M. oblongifolia Arechav., M. resedoides A. St.-Hil. & Moq., M. richardiana A. St.-Hil. & Moq., M. stenophylla A. St.-Hil. & Moq. e M. tristaniana A. St.-Hil. & Moq. Neste trabalho são fornecidas... |
