Orchidaceas do estado do Maranhão, Brasil 1

Abstract

RESUMO -O Estado do Maranhão faz parte da Amazônia Legal e tem sido um dos mais atingidos pelos projetos impactadores do meio ambiente, causando sérios riscos de extinção de espécies vegetais e animais, algumas, ainda desconhecidas pela ciência. Com o objetivo de conhecer a flora orquídica daquele Estado foram conduzidos estudos ao longo de aproximadamente 12 anos, registrando-se a ocorrência de 103 diferentes espécies de Orchidaceae. Os resultados demonstraram a grande riqueza em espécies nesta família, e o quanto ela era desconhecida, uma vez que antes deste estudo, conheciase pela literatura, apenas dez espécies ocorrendo no Estado do Maranhão. PALAVRAS CHAVE: Orchidaceae, Amazônia Legal, Diversidade Checklist of Orchidaceae from State of Maranhão, Brazil.ABSTRACT -The Maranhão State is part of "Amazônia Legal", and has been one of the most affected by the impacts of projects to environment, and leading to extintion many species of plants and animals, some of them not discovered by science.

Vanilla bahiana Hoehne and Vanilla pompona Schiede (Orchidaceae, Vanilloideae): two new records from Maranhão state, Brazil

“…Pabst andDungs (1975, 1977) reported only 10 species from the Brazilian state of Maranhão. Silva et al (1999) reported 103 orchid species in the region, distributed over 48 genera. More research on the Orchidaceae has been carried out in Maranhão after the study conducted by Silva et al (1999), and currently 122 species and 53 genera of orchids (Brazilian Flora 2017) are reported to the state.…”

Richness of Marchantiophyta and Bryophyta in a protected area of the Brazilian Amazon

“…The richness of the flora and floristic composition is partially known through phytosociological surveys of tree species, studies on flowering and fruiting patterns of trees and inventories of bee flora and Orchidaceae (Muniz 1998(Muniz , 2008(Muniz , 2011Silva et al 1999;Marques et al 2011).…”

Ornamental potential of species from the ferruginous Campo rupestre of the Carajás National Forest, Brazilian Amazon

“…(Table 2). (Silva et al, 1999;Mania & Monteiro, 2010, Petini-Benelli & Castro, 2015. This variation of environments can be an important characteristic for the elaboration of conservation and domestication strategies for these species outside their natural environment.…”
