Selection of native trees for intercropping with coffee in the Atlantic Rainforest biome

A challenge in establishing agroforestry systems is ensuring that farmers are interested in the tree species, and are aware of how to adequately manage these species. This challenge was tackled in the Atlantic Rainforest biome (Brazil), where a participatory trial with agroforestry coffee systems was carried out, followed by a participatory systematisation of the farmers experiences. Our objective was to identify the main tree species used by farmers as well as their criteria for selecting or rejecting tree species. Furthermore, we aimed to present a specific inventory of trees of the Leguminosae family. In order to collect the data, we reviewed the bibliography of the participatory trial, visited and interviewed the farmers and organised workshops with them. The main farmers’ criteria for selecting tree species were compatibility with coffee, amount of biomass, production and the labour needed for tree management. The farmers listed 85 tree species; we recorded 28 tree species of the Leguminosae family. Most trees were either native to the biome or exotic fruit trees. In order to design and manage complex agroforestry systems, family farmers need sufficient knowledge and autonomy, which can be reinforced when a participatory methodology is used for developing on-farm agroforestry systems. In the case presented, the farmers learned how to manage, reclaim and conserve their land. The diversification of production, especially with fruit, contributes to food security and to a low cost/benefit ratio of agroforestry systems. The investigated agroforestry systems showed potential to restore the degraded landscape of the Atlantic Rainforest biome.

Three New Species of Mimosa (Leguminosae) from Minas Gerais, Brazil

Abstract Three new species of Mimosa (Leguminosae, Mimosoideae), from the campos rupestres of the state of Minas Gerais, Brazil, are described and illustrated. The species are from section Batocaulon DC. ( Mimosa mitzi and Mimosa rubra ) and section Calothamnos Barneby ( Mimosa longistipula). Mimosa longistipula is similar to M. flocculosa but mainly differs from it by the stellate trichomes found throughout its corolla. Mimosa mitzi is morphologically similar to Mimosa hexandra and Mimosa exalbescens. However, it can be distinguished from M. hexandra by its free stamens and the presence of paraphyllidia, and from M. exalbescens by the larger leaves and smaller number of leaflets. Mimosa rubra is morphologically similar to M. minarum, but is easily recognized by the reddish color of its stems and leaves. The three species described here are restricted to the state of Minas Gerais and are critically endangered according to the IUCN criteria. A discussion on the distribution, habitat, phenology, conservation status, etymology, and notes about morphologically similar species is provided, along with keys to their closest relatives.

Papilionoideae (Leguminosae) arbóreas e lianas na estação depesquisa, treinamento e educação ambiental (EPTEA), Mata doParaíso, Viçosa, Zona da Mata Mineira

This work is a floristic survey of trees and lianas of the Papilionoideae in the Mata do Paraiso, an important fragment of Submontane Semideciduous Seasonal Forest, in Vicosa, Zona da Mata Mineira. The fieldwork was carried out through visits to the studied area, from July/2004 to August/2005. Twelve taxa represented by eight genera were recorded. Machaerium Pers. (4spp.) and Dalbergia L. f. (2 spp.) were the most representatives. Identification keys, descriptions and illustrations are presented for the analyzed taxa. Dalbergia nigra (Vell.) Allemao ex Benth., vulnerable species and, Ormosia vicosana Rudd, endemic for the region were found at EPTEA.

Asteraceae Dumort nos campos rupestres do Parque Estadual do Itacolomi, Minas Gerais, Brasil: Barnadesieae e Mutisieae

The study of the tribes Barnadesieae and Mutisieae is part of the floristic inventory of Asteraceae species in the rocky fields (campos rupestres) of the Parque Estadual do Itacolomi (PEI) in Minas Gerais. The collections were carried out between in the period from August 2005 to August 2007. For the two tribes this study identified 21 species belonging to six generas: Dasyphyllum Kunth with four species and one variety; Chaptalia Vent. (four species), Gochnatia Kunth. (three species), Mutisia L.f. (one species), Richterago Kuntze (six species) and Trixis P. Br. (three species). Most of these species are restricted to the rocky fields of the Espinhaco Range or vegetated areas near the transition, being four endemic of the Minas Gerais states. Keys for the identification of genera and species, descriptions, taxonomic commentaries, information about the geographical distributions of species and illustrations are presented.

Geographic distribution patterns of Leguminosae and their relevance for the conservation of the Itacolomi State Park, Minas Gerais, Brazil

This study identified patterns of geographic distribution of 102 Leguminosae taxa within the Park, based on literature data and herbarium specimens. Among the taxa, 38 grow exclusively in CamposRupestres (rocky fields) and 49 in the Semideciduous Forest. Eleven patterns of geographic distribution were identified, of which the West-East-Central South America pattern was the most representative, with 27 taxa. Of the 102 sampled taxa of Leguminosae, five are endemic to the Espinhaco Range and ten are included in lists of endangered species of the flora of Brazil and Minas Gerais. Information on these taxa is crucial to provide conservation practices for conserving the vegetation formations of the PEIT.
