An interactive key (Lucid) for the identifying of the genera of seed plants from the Ducke Reserve, Manaus, AM, Brazil

The identification of Amazonian plants is still difficult for many reasons, one being the lack of collections over large areas of the region. As a consequence of the poor knowledge on the Amazonian flora, many taxonomic publications (revisions and floristic treatments) become out of date within a few years. In this context, the on-line publication of taxonomic treatises has been suggested, since it allows constant data updates; and this type of publication should therefore be more valued by the scientific community. An excellent field guide for the Ducke Reserve (Manaus, central Amazonian Brazil) was published, based exclusively on vegetative characters. However, the presence of reproductive structures in the collected material does not facilitate identification with this type of field guide. Furthermore, as in any printed key, the text cannot be updated, except through a new edition. As an example of a way to facilitate the identification of Amazonian plants, an interactive, multiple-entry key to the seed plant genera that occur in the Ducke Reserve was created using the program Lucid 3.5. The key includes vegetative and reproductive characters and many illustrations, and is available on-line. We discuss here the peculiarities and advantages of this type of electronic publication

Checklist of Spermatophyta of the São Paulo State, Brazil

The Phanerogamic Flora of São Paulo State project has been dedicated to create an inventory of the flora for 20 years. More than 200 collaborators are involved, mostly from the State of São Paulo, with the contributions of researchers from other states and from abroad. Since 2001, seven books with monographs of 151 families were published, dealing with 3,237 species within 722 genera. This project was the starting-point of the gathering of information about the diversity of spermatophytes of the State of São Paulo. The current checklist, at this point, presents an updated and virtually complete list of species, all certified by specialists. It also contains references to scientific collections for most of the taxa (vouchers) or to bibliography referring to the natural or subspontaneous occurrence of the species in the State. The list now contains 7,305 species distributed in 1,776 genera and in 197 spermatophyte families (according to Cronquist 1981) or 195 (according to APG III). 23% of the 31,728 species of spermatophytes listed in the Flora of Brazil occur in São Paulo State. The most representative families are Orchidaceae (797 species), Asteraceae (676 species), Fabaceae (513 species), Poaceae (500 species), Myrtaceae (304), Rubiaceae (265 species) and Melastomataceae (253 species), which, altogether, accumulate 3,308 species and constitute 45% of total species of spermatophytes in the state. The wealth of the Brazilian plant diversity, partially expressed in São Paulo, shows how important is the continuity of floristic studies in a country that is very likely to hold the largest plant diversity in the planet.O projeto Flora Fanerogâmica do Estado de São Paulo tem se dedicado a inventariar a flora paulistana há quase 20 anos. Conta com a atuação de mais de 200 colaboradores, a maioria do próprio estado, além de pesquisadores de outros estados e do exterior. Desde 2001, foram publicados sete volumes com as monografias de 151 famílias, contendo 3.237 espécies em 722 gêneros. Este projeto foi o ponto de partida para o conhecimento da diversidade das espécies de espermatófitas do estado de São Paulo. A apresentação do checklist neste momento é oportuna por constituir a produção de uma listagem das espécies com identificações certificadas pelos especialistas, além de conter a referência de uma coleção de herbário para a maior parte dos táxons (material-testemunho) ou referência à bibliografia em que a espécie é citada como ocorrente, de forma nativa ou subespontânea, no estado. Dessa forma, é aqui apresentada a listagem das espermatófitas do estado de São Paulo, com 7.305 espécies, distribuídas em 1.776 gêneros e em 197 famílias (segundo Cronquist 1981) ou então 195 (segundo o APG III). Em relação à flora do Brasil, com 31.728 espécies de espermatófitas, o estado São Paulo compartilha de 23% dessas espécies. As famílias mais representativas são Orchidaceae (797 espécies), Asteraceae (676 espécies), Fabaceae (513 espécies), Poaceae (500 espécies), Myrtaceae (304), Rubiaceae (265 espécies) e Melastomataceae (253 espécies) que, juntas, somam 3.308 espécies e constituem mais de 45% do total de espécies de espermatófitas do estado. Considerando a grande diversidade vegetal brasileira, parcialmente expressa em um estado, depreende-se a grande importância da continuidade dos estudos florísticos no Brasil, país provavelmente detentor da maior diversidade vegetal do planeta.19138

Transference of function in the pollination system of the Ochnaceae

Most members of the Ochnaceae possess poricidal anthers that are emptied by pollen collecting bees performing vibrational foraging. In several genera, such as Tyleria, Adenarake, and various species of Sauvagesia, however, pollen is released by vibration from the anthers through the porus of a novel structure formed by staminodia. These envelop the androecium and gynoecium. Anthers enclosed in this envelope are often longicidal. © 1991 Springer-Verlag

Pollination biology of Ternstroemia laevigata and T. dentata (Theaceae)

The flowers of two species of Ternstroemia from Central Amazonia were observed to be pollinated by female bees performing vibrational foraging. The anthers of these flowers are longitudinally dehiscent. They are completely included in a petal tube, which opens by a small pore at the apex. Pollen is expelled out of this pore when the bees vibrate the flower while curling over the apex of the petal tube. The much elongated connectives probably transmit the vibrations from the petals to the anthers. The possible occurrence of this mode of pollination in other species of Ternstroemia is briefly discussed. © 1993 Springer-Verlag
