E-mail: Abstract: The Rondônia Natural Resources Management Project (PLANAFLORO) was a strategic program developed in partnership between the Brazilian Government and The World Bank in 1992, with the purpose of stimulating the sustainable development and protection of the Amazon in the state of Rondônia. More than a decade after the PLANAFORO program concluded, the aim of the present work is to recover and share the information from the long-abandoned plant collections made during the project’s ecological-economic zoning phase. Most of the material analyzed was sterile, but the fertile voucher specimens recovered are listed here. The material examined represents 378 species in 234 genera and 76 families of angiosperms. Some 8 genera, 68 species, 3 subspecies and 1 variety are new records for Rondônia State. It is our intention that this information will stimulate future studies and contribute to a better understanding and more effective conservation of the plant diversity in the southwestern Amazon of Brazil. Introduction The PLANAFLORO Project funded botanical expeditions In early 1990, Brazilian Amazon was facing remarkably in different areas of the state to inventory arboreal plants high rates of forest conversion (Laurance et al. -

IAWA Journal, Vol. 27 (2), 2006: 129–136 WOOD ANATOMY OF CRAIGIA (MALVALES) FROM SOUTHEASTERN YUNNAN, CHINA Steven R. Manchester1, Zhiduan Chen2 and Zhekun Zhou3 SUMMARY Wood anatomy of Craigia W.W. Sm. & W.E. Evans (Malvaceae s.l.), a tree endemic to China and Vietnam, is described in order to provide new characters for assessing its affinities relative to other malvalean genera. Craigia has very low-density wood, with abundant diffuse-in-aggre- gate axial parenchyma and tile cells of the Pterospermum type in the multiseriate rays. Although Craigia is distinct from Tilia by the pres- ence of tile cells, they share the feature of helically thickened vessels – supportive of the sister group status suggested for these two genera by other morphological characters and preliminary molecular data. Although Craigia is well represented in the fossil record based on fruits, we were unable to locate fossil woods corresponding in anatomy to that of the extant genus. Key words: Craigia, Tilia, Malvaceae, wood anatomy, tile cells. INTRODUCTION The genus Craigia is endemic to eastern Asia today, with two species in southern China, one of which also extends into northern Vietnam and southeastern Tibet. The genus was initially placed in Sterculiaceae (Smith & Evans 1921; Hsue 1975), then Tiliaceae (Ren 1989; Ying et al. 1993), and more recently in the broadly circumscribed Malvaceae s.l. (including Sterculiaceae, Tiliaceae, and Bombacaceae) (Judd & Manchester 1997; Alverson et al. 1999; Kubitzki & Bayer 2003). Similarities in pollen morphology and staminodes (Judd & Manchester 1997), and chloroplast gene sequence data (Alverson et al. 1999) have suggested a sister relationship to Tilia. -

388 Desiccation tolerance of Tapirira obtusa seeds collected from different environments1 Wilson Vicente Souza Pereira2*, José Márcio Rocha Faria2, Olivia Alvina Oliveira Tonetti2, Edvaldo Aparecido Amaral da Silva3 ABSTRACT – This study was aimed at evaluating the desiccation sensitivity in seeds of the tree Tapirira obtusa (Benth.) J. D. Mitchell collected from three different environments and subjected to two distinct drying speeds. Seeds were collected from a rocky area, in the “Cerrado”, and in a riparian forest area, in the region of municipality of Lavras, State of Minas Gerais. The seeds were subjected to drying with magnesium chloride (slow drying) or silica gel (fast drying), into closed environment, until moisture contents of 40%, 30%, 20% and 10%, considering as control, the percentage of germination at the initial moisture content in each environment, which varied from 47% to 50%. Percentages of germination and normal seedlings as well as germination speed index were assessed. For the three environments studied, there was no effect of slow drying on seed germination. Seeds from area of Cerrado, however, have shown a slight reduction on germination when subjected to fast drying. Oppositely, seeds from rocky area had germination increased when subjected to fast drying. Seeds from riparian forest area had no reduction on germination percentage, independent of drying speed. Results suggest that seeds of T. obtusa are not sensitive to desiccation. Index terms: drying, germination, sensitivity, dehydration.

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer. -
Biodiversity in Forests of the Ancient Maya Lowlands and Genetic
Biodiversity in Forests of the Ancient Maya Lowlands and Genetic Variation in a Dominant Tree, Manilkara zapota (Sapotaceae): Ecological and Anthropogenic Implications by Kim M. Thompson B.A. Thomas More College M.Ed. University of Cincinnati A Dissertation submitted to the University of Cincinnati, Department of Biological Sciences McMicken College of Arts and Sciences for the degree of Doctor of Philosophy October 25, 2013 Committee Chair: David L. Lentz ABSTRACT The overall goal of this study was to determine if there are associations between silviculture practices of the ancient Maya and the biodiversity of the modern forest. This was accomplished by conducting paleoethnobotanical, ecological and genetic investigations at reforested but historically urbanized ancient Maya ceremonial centers. The first part of our investigation was conducted at Tikal National Park, where we surveyed the tree community of the modern forest and recovered preserved plant remains from ancient Maya archaeological contexts. The second set of investigations focused on genetic variation and structure in Manilkara zapota (L.) P. Royen, one of the dominant trees in both the modern forest and the paleoethnobotanical remains at Tikal. We hypothesized that the dominant trees at Tikal would be positively correlated with the most abundant ancient plant remains recovered from the site and that these trees would have higher economic value for contemporary Maya cultures than trees that were not dominant. We identified 124 species of trees and vines in 43 families. Moderate levels of evenness (J=0.69-0.80) were observed among tree species with shared levels of dominance (1-D=0.94). From the paleoethnobotanical remains, we identified a total of 77 morphospecies of woods representing at least 31 plant families with 38 identified to the species level. -

INTRODUCTION Up till now relatively little work has been done on the cytology of South Ameri- can plants. The following authors published some data on chromosomenumbers of South Böcher American species: Argentina: c.s. (1963); Covas (1949); Covas & Hunziker (1954); Covas & Schnack (1947); Rahn(1960); Schnack & Covas (1947); Chile: de Tschischow (1956); Colombia: Shibata (1962); Ecuador: Heiser (1963); Peru: Diers (1961); Huynh (1965); Suriname; Gadella & Kliphuis (1964). Besides these documentedlists of chromosome numbers also incidental studies carried out in various of some were genera Angiospermae, but in general the conclusion can be drawn that - especially in comparison with Europe, Japan and North America - much is still to be done in the field of cytology before a more satisfactory picture can be obtained. With this situation in mind the third author started three years ago on a trip to Brazil accompanied by the advanced student J. H. de Haas. The principal aim was to study the composition of the endangered primary forests in the southern state of Parana. It soon became evident that fixation of roottips in the could carried in field not be out the already tight program. -

DNA Barcoding and Phylogenetic Analysis of Searsia
Poster ID : 828 DNA barcoding and phylogenetic analysis of Searsia Makhado Tshililo, Michelle van der Bank and Sanele N. S. Shiba The African Centre for DNA Barcoding (ACDB), Department of Botany & Plant Biotechnology, University of Johannesburg, South Africa ABSTRACT Background. The family Anacardiaceae includes approximately 800 species in 82 genera. Rhus L. is the largest and most widely distributed genus in Anacardiaceae. However, controversy has surrounded the delimitation of the genus. Searsia F.A. Barkley was originally included into the Rhus complex but recent molecular studies have separated it along with six other genera from the Rhus complex and recognised them as separate genera. The genus Searsia, which is the focus of the current study, is represented by approximately 120 species and is widely distributed in Africa with only three species currently known from Asia. Here we include an extensive sampling and molecular analyses of Searsia species across its distribution range in Africa to access the relationships within the genus. Results. In total 205 taxa, representing 35 species of Searsia, were sequenced for the core barcoding regions (matK and rbcLa) along with additional markers, i.e. ITS, ETS, trnL-F and ndhF. Significance. This study contributes a first large sampling of Searsia. An infrageneric classification for the genus will be presented.
