Polyandrococos was a Micronutrient Deficiencies None observed monotypic genus but was combined with Allagoptera. Insect Damage None observed Allagoptera is closely related to Attalea, Lytocaryum, and Hurricane Resistance Excellent Syagrus. Allagoptera caudescens is a monoecious palm with a solitary stem usually 12 to 24 feet tall in habitat, but the stem can also be short or subterranean. The fronds are pinnate with an extremely short petiole. These palms are native to lowland tropical rainforest along the coast of Brazil at elevation of up to 1,000 feet. They are reported to persist in cleared areas which indicate they will tolerate full sun exposure. I have three specimens planted in the shade in an area which is prone to flooding during heavy rain. Dale Holton and Ruth Sallenbach also have their palms planted in the shade.

  • 6 Latin American Region
    Tropical Palms 119 6 LATIN AMERICAN REGION New World palms and their products is the subject of this chapter. The region is defined as extending north-south from Mexico to Chile and Argentina, and including the islands of the Caribbean. Palm species diversity in this region is second only to Asia. Glassman (1972) recognized over 1,100 palm species in the Americas (including the United States). However, in a field guide to New World palms, Henderson et al. (1995) consider there to be only 550 palm species native to the Americas. This significant difference in species totals is attributable to the many synonymous names included in the higher figure and the fact that Henderson et al. (1995) follow a broad species concept resulting in the lower number. Over the last two decades, research in the biological and social sciences has helped to generate a reliable body of knowledge about the utilization patterns and scientific names of Latin American palms. This knowledge has come from several different approaches, and can be illustrated by the following examples grouped into five categories. General palm studies. The survey of the major underutilized palms of tropical America (FAO/CATIE, 1984) is an excellent source of information. Papers in the palm symposium proceedings (Balick, 1988b) primarily deal with the Latin American region. Balick (1984, 1989) also has provided surveys of palm ethnobotany and diversity of use in the region. A natural resource approach was used by Kahn (1991) in a study of palms in swamp forests of the Amazon. Kahn and de Granville (1992), in their study of palm forest ecosystems of Amazonia, provide data on leaf and fruit productivity which have direct relevance to exploiting palm products.

Abstract Mechanisms of genome evolution are fundamental to our understanding of adaptation and the generation and maintenance of biodiversity, yet genome dynamics are still poorly characterized in many clades. Strong correlations between variation in genomic attributes and species diversity across the plant tree of life suggest that polyploidy or other mechanisms of genome size change confer selective advantages due to the introduction of genomic novelty.

Universidade Federal de Sergipe - UFS, Laboratório Biologia da Conservação, Departamento de Biologia, São Cristóvão, SE, Brazil. [email protected]; 2. Universidade Federal de Sergipe – UFS, Graduate in Ciências Florestal, São Cristóvão, SE, Brazil; 3. Universidade Federal de Alagoas, Centro de Ciências Agrárias. Rio Largo, AL, Brasil. ABSTRACT: The aim of this study was to obtain information on the floristic composition and dispersal syndromes of the Ibura National Forest and carry out an analysis of similarity with other floristic surveys in the state of Sergipe. For this purpose, bimonthly sampling was carried out from September 2012 to December 2014. Total of 328 species were recorded, of which 324 were angiosperms belonging to 82 families, followed by three species of ferns and lycophytes and one species of Gymnosperm. Sixty-seven new species were recorded for the state of Sergipe. The richest families in species were Fabaceae, Myrtaceae, Rubiaceae, Asteraceae, Euphorbiaceae and Malvaceae. Regarding the dispersal syndromes, the dominance of zoochoric dispersal was observed, followed by autochoric and anemochoric dispersal. Among the tree and shrub species, the zoochoric syndrome was predominant (70%), while herbaceous species showed predominance of autochoric species (49%), and climber species have a more equitable proportion among the syndromes (38% autochoric, 32% anemocoric and 30% zoochoric). The Ibura National Forest presented relatively low levels of similarity with other sites located in the Atlantic Forest, possibly influenced by its isolation and distance between fragments.
