O artigo analisa a atuação de frei Veloso como naturalista e busca demonstrar que tanto sua atividade de botânico quanto o trabalho de editor eram consistentes com as características da história ...natural do Iluminismo. A celebridade adquirida posteriormente por Veloso foi sendo construída no âmbito da exaltação de “grandes homens” do período colonial e na utilização de suas pesquisas pela botânica. O fato de Veloso e sua equipe terem adotado o sistema lineano permitiu que sua obra fosse reconhecida pelos taxonomistas como válida, mesmo posteriormente, apesar de estar desatualizada na época de sua publicação.
Atlas Florae Europaeae (AFE), a programme for mapping the distribution of vascular plants in Europe, was launched in 1965 as a collaborative effort between European botanists. A historical review of ...the mapping for AFE in the Balkan countries, cited in the last volume (16) from 2013 as Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Former Yugoslav Republic (F. Y. R.) of Macedonia, Greece, Kosovo, Montenegro, Serbia, Slovenia, and Turkey (European part), is presented and achievements and problems discussed. The special challenges facing mapping of the Balkan area during the past 50 years include the extremely rich flora, diverse and mountainous relief, political and economic difficulties, inaccessibility of available data, and scarcity of botanists contributing and collecting data for mapping.
Priority concerning the publication of St. Hilaire's name Hypericum cordiforme over H. cordatum is confirmed since its effective publication in Flora Brasiliae Meridionalis (1828) predates the ...publication of Vellozo's name Receveura cordata, the basionym of H. cordatum, in Florae fluminensis (1829). We also provide a second-step lectotypification for H. cordiforme and a lectotypiflcation and epitypification for Receveura cordata. Hypericum cordiforme var. genuinum is for the first time determined to be an invalid name, and H. cordatum subsp. kleinii is placed in the synonymy of H. cordiforme.
The small-leaved forests of the north of Novosibirsk region were investigated. The comparative analysis of structure and floristic composition of the communities with and without fire marks was ...carried out. As found, 167 species of higher vascular plants (45 % of the total) are a part of both partial florae. The partial flora of the burned forests includes more species, i.e. 250, than that of the forests without fire marks. Among them, 83 species are found only in the burned forests. The partial flora of the forests without fire marks includes 205 species, with 39 specific species. We found that periodic local fires slightly change structure and floristic composition
Este artículo muestra que en las décadas finales del siglo XVIII, más allá de las relaciones diplomáticas y los conflictos militares entre Portugal y España, existieron importantes conexiones ...científicas, que han sido poco estudiadas. Teniendo como punto de partida la casi desconocida Specimen Florae Americae Meridionalis (1780), una obra botánica compuesta de cuatro volúmenes, producida en el Real Museu da Ajuda (Lisboa), exploraremos el interés que suscitó en los círculos de estudiosos y aficionados a la botánica en Lisboa la llegada de más de doscientos dibujos de plantas procedentes de la Real Expedición Botánica al Virreinato del Perú (1777-1788). Considerando las personalidades portuguesas, españolas e inglesas que estuvieron implicadas en la presencia de estos diseños en Portugal, recuperaremos algunas de las prácticas que posibilitaban en este período la circulación de conocimientos científicos y el adelanto de la botánica. En este sentido, este estudio pretende realizar una aportación novedosa a la Historia de la Botánica en Portugal y España y apuntar caminos para futuras investigaciones.
This study refers to specimens of Lauraceae collected in Brazil by Carl Friedrich Philipp von Martius between 1817 and 1820. He collected 57 currently accepted species of Lauraceae, which belong to ...nine genera: Aniba, Cassytha, Cinnamomum, Cryptocarya, Dicypellium, Licaria, Nectandra, Ocotea, and Persea, for which Martius is known to have made about 99 different collections. The vast majority of them are nomenclatural types and, taking into account the synonyms involved, encompassing 26 holotypes, 23 lectotypes, and 30 syntypes. Besides Martius himself, early descriptions and citations of these materials were made by Nees von Esenbeck, Meissner, and Mez, the first monographers of the family. Martius's collections were the basis for the Flora Brasiliensis, where the taxonomic treatment of Lauraceae was made by the Swiss botanist Carl Daniel Friedrich Meissner in 1866, being of particular interest for indicating all the collections examined and available at that time. Here, we provide an annotated and updated list of 60 entries with information on the status of the names and their types, currently accepted names, collections found in different herbaria, accompanied by an Index to Scientific names and an Index to Collections. Although there are no cases of specimens of Lauraceae collected by Martius from his “Martii Herbarium Florae Brasiliensis,” they are also listed here since they have been attributed to him in literature. Lectotypes for two names, Cryptocarya speciosa, and Nectandra nitidula var. maior, are designated, and a new synonymy is proposed.
Gathering information on the bee foraging plants in a given area is of primary importance in the development of any apiculture industry. Analysis of the honey produced in hives as well as the stored ...pollen loads help to evaluate the sources of nectar and pollen used by honey bees and their behavioural pattern in the selection of preferences for certain plants as food. Our previous melissopalynology study focused on the analysis of the Omani honey from hives in 14 locations of Muscat and the Al Batinah regions. Our current study examines the pollen pellets collected from those same areas. A total of 249 pollen pellets from 22 honeycombs that were collected by Apis florea and Apis mellifera honeybees were processed and the pollen types were identified using light and scanning electron microscopy. Each pollen load was designated as a unifloral, bifloral or multifloral type. Each plant taxon identified was categorized as being utilized by honeybees for pollen only, nectar only or for both pollen and nectar. A pollen reference collection of 105 local flowering plants was prepared that enabled us to identify most of the pollen types. The quantification of 94 pollen types revealed that 67 of them belonged to 39 plant families, all of which are represented in both the pollen loads and the honey samples. Seven pollen genera were found in the pollen loads only and suggest that those plants were visited by bees just for pollen. Twenty pollen types appear only in the honey samples and suggest that bees visited them only for nectar. Major bee foraging plant species include: Ziziphus spinachristi, Acacia tortilis, Prosopis cineraria, Prosopis juliflora, Maerua crassifolia, Citrus spp., Zygophyllum spp. and Fagonia spp. These data provide a guide to the optimal utilization of floral resources by honeybees in these regions.

A melissopalynological study of Omani honeys was undertaken to determine floral sources, and identify pollen types, that would indicate the ecological origins. The study comprised the analysis of 48 ...honey samples collected during 2001-2003 from 14 locations in the Muscat and Al Batinah regions of Oman. The beehives and nests examined were either those of Apis florea or Apis mellifera bee colonies. A total of 122 pollen types, representing 50 plant families, were identified. Each taxon was categorized as representing a major or minor source of nectar and pollen. Thirty-two honey samples are unifloral types, and the remaining 16 are multifloral. Honey is harvested twice a year in Oman, once in the summer and again in the winter. The pollen data indicate that Ziziphus spina-christi, Prosopis juliflora, Prosopis cineraria and constitute the chief nectar and pollen sources for honeybees in this area during the winter. By contrast during the summer, Acacia tortilis, Citrus sp., Maerua crassifolia, Phoenix dactylifera, Prosopis cineraria, and Prosopis juliflora are the more important nectar sources. This study has identified a wide range of foraging plant sources for honeybees and demonstrates adequate potential for expanding and sustaining beekeeping in Muscat, and in the Al Batinah region. A modern pollen reference collection of 105 local floral species enabled the identification of the pollen types. Seventy-four pollen types were found in the 48 honey samples. The identifications of pollen types are based on both light and scanning electron microscope (SEM) studies of the pollen in the honey and reference samples.
