P031-00 Pollination biology of Piperaceae species in southeastern Brazil Figueiredo RA, Sazima M* Phenology, floral biology and breeding system are described for 14 Piperaceae species at two sites covered by semi-decidouous fores in southeastern Brazil. Flowering occurred continuously throughout the year, with a peak during the windy months. All species had minute odorous and nectarless flowers visited by insects; five of them showed a substantial degree of self-compatibility, and one was andromonoecious. Seven species were wind pollinated, and three were exclusively pollinated by insects. Flower visitors were mainly hoverflies and bees. Annals of Botany 85: 455-460, 2000. IF = 1.326 *E-mail:
P032-00 Two new Melastomataceae from São Paulo, Brazil Goldenberg R, Martins AB* The genus Meriania Swartz has 74 species distributed from Southern Mexico and West Indies to Southeastern Brazil (Renner 1993, Almeda 1993). Only tree species occur in the state of São Paulo, all along the northern portion of the "Serra do Mar". The genus Miconia Ruiz & Pav. has ca. 1.060 species (Goldenberg in prep.), distributed from Southern Mexico to Southern Brazil, Paraguay and Northern Argentina. Martins et al. (1996) listed 53 species for São Paulo, occurring in almost all vegetation types in the state. Two new species were found during the preparation of the treatments of Miconia and Meriania for the "Flora Fanerogâmica do Estado de São Paulo". Both were collected on slopes between 100 and 900m above sea level in the "Parque Estadual da Serra do Mar, Núcleo de Picinguaba", at the eastern tip of São Paulo, near the Rio de Janeiro state border.

P033-00 Morfologia dos tricomas em Tibouchina sect. Pleroma (D. Don) cogn. Guimarães PJF, Martins AB* (Morphology of trichomes in Tibouchina section Pleroma (D. Don) Cogn. (Melastomataceae). The Melastomataceae display greater trichome diversity. Dr. Wurdack, in his Atlas of hairs, recognized 46 types of trichomes for the Neotropical Melastomataceae through the SEM, and referred 17 of them to the genus Tibouchina. Th e trichomes morphology has been extensively used in the delimitation of the taxa in Melastomataceae, as well as in previous studies by Cogniaux, the monograph of Brazilian Melastomataceae published in 1885. The morphology of the trichomes was essential for the delimitation of several species in Tibouchina section Pleroma. The use of SEM provided the best characterization of the 15 different types of trichomes recognized among the 41 species examined. These were described based on the morphological appearance, both OM and SEM, and illustrated by scanning electron micrographs and photomicrographs.

P036-00 New combinations and a new species in Brazilian genus Chaetostoma DC. (Microlicieae: Melastomataceae) Koschnitzke C, Martins AB* Four new combinations (Chaetostoma albiflorum, C. Cupressinum, C. Selagineum, C. Stenocladon), are proposed and a new species, Chaetostoma flavum, endemic to the Chapada dos Veadeiros, Goiás, Brazil is described. The new species can be distinguished by its 4-5 locular ovary and antesepalous stamens with prolonged appendages. Novon 9(2): 202-204, 2000. IF = 0.215 *E-mail:

P038-00 A new species of Marcetia (Melastomataceae) from Brazil Martins AB*, Woodgyer EM Marcetia is a neotropical genus that can be distinguished within the Melastomeae (= Tibouchineae) principally by the combination of tetramerous flowers, eglandular leaves and simple anthers which lack both basally prolonged connectives and ventral appendages. With just one exception, the genus is endemic to Brazil where its 28 species are of very limited distribution, occurring mainly in areas of campo rupestre vegetation. In 1980 a long-term collaborative programme was established between the Royal Botanic Gardens, Kew and the University of São Paulo, resulting in a series of successful joint expeditions to the mountains of Minas Gerais and Bahia. These expeditions have disclosed several new species of Marcetia, one of which is described here. Kew Bulletin 55:189-193, 2000. *E-mail:
P039-00 Aspectos da germinação e do crescimento de Callophyllum brasiliense (Clusiaceae) , uma espécie típica de locais inundados Marques MCM*, Joly CA* Seed germination and growth of Calophyllum brasiliense (Clusiaceae), a typical species of flooded forests). Soil waterlogging and the subsequent reduction in the amount of oxygen available for the respiration of the root system selected, along the evolutive process, plants able to thrive in seasonally or permanently flooded areas. In neotropical plants there are many types of adaptations to flooding. In this paper we present the results of the work carried out with seeds and seedlings of C. brasiliense subjected to hypoxia during germination and early development. C. brasiliense seeds are not photoblastic and survive up to three months burred in a water saturated substrate, but germination only takes place in well-drained soils. Soil waterlogging does not inhibit seedling growth and there are no apparent morphological changes of the aerial part of flooded plants. New and aerated roots that make possible the plant survival, replace old and spoiled roots. In contrast with many species typical of flood-prone areas which growth is inhibited by oxygen stress, C. brasiliense seedlings seems to be well adapted to its waterlogged environment. The species wide geographic distribution, always associated with areas subjected to soil waterlogging, is probably linked to the opportunistic character shown by C. brasiliense regarding seed dispersion, the absence of photoblastic response as well as seed and seedling capacity of surviving and growing in waterlogged soils.
