ABSTRACT. The Orchidaceae represent one of the largest and most diverse families on the planet. However, this family is constantly threatened by predators and by the advancement of urban centers over its natural habitats. The objective of this study was to use inter-simple sequence repeat markers to evaluate the genetic diversity between orchid accessions of the Laeliinae subtribe, which comprise part of the Orchidaceae study collection at the Department of Agronomic Engineering of the Federal University of Sergipe. DNA was extracted from each specimen by using an adapted 2% cetyltrimethyl ammonium bromide protocol. Similarity between individuals was calculated using the Jaccard method. Clustering was carried out by the unweighted pair group method with arithmetic mean method, with resampling and 10,000 bootstraps. Eighty-seven fragments were obtained, all of which were polymorphic, revealing high variability between accessions. The mean similarity was 35.77% between Encyclia sp individuals, and 35.90% between specimens of Cattleya tigrina. For Epidendrum secundum, a relationship between geographic and genetic distances was observed, and the accession collected in the southern part of the State of Sergipe (Serra de Itabaiana National Park) was more divergent than that of the other parts of the state. The data generated in this study will guide further research aimed at the ex situ conservation of these materials.

“…A survey on Orchidaceae carried out in the State of Sergipe resulted in a list of 63 species, 34 of which were new records for the state (Monteiro et al, 2012a). Inventories carried out in Sergipe territory also served to include the state in the distribution map of some species, such as Encyclia alboxanthina Fowlie (Monteiro et al, 2012b).…”

“…correspond to about 46 % of the species. Representatives of Laeliinae make up a large part of the orchid flora in the Neotropics (Van den Berg 2000) and have been pointed out as the most representative orchid subtribe in other studies in northeastern Brazil (Pessoa & Alves 2015;Monteiro et al 2012). Habenaria has been found to be the most species-rich in areas of Cerrado, such as in the Federal District (Batista & Bianchetti 2003), and Catasetum is especially diverse in the transition zone between Amazon and Cerrado, as pointed out by Petini-Benelli (2012) for the Brazilian state of Mato Grosso.…”

An updated checklist reveals strong incongruities with previous studies: insights after revisiting a regional orchid list

et al. 2022

An updated checklist of the Orchidaceae from the state of Maranhão is provided. We confirmed 51 genera and 119 species, of which the most representative genera are Habenaria (17 spp.), Catasetum (14 spp.) and Epidendrum (10 spp.). Our checklist includes 30 species that are not listed in the Flora do Brasil for the state, many of which, however, have been recorded in previous publications. Thus, excluding these, six species are cited here for the first time to Maranhão, all of which are also new records for the Brazilian Northeast region. Comparing such data with previous lists, with 103 and 105 species, we detected a strong incongruity among the data. Of the former list, 25 species lack vouchers from the state and were not collected in our expeditions, thus these taxa are not confirmed, while of the latter we found 20 species that are also not confirmed for the same reasons. A list with the 34 excluded taxa is provided. Most of the collection effort in the state coincides with university campuses, and the northwestern region is the most species rich, but unfortunately it is also the most threatened area.

“…Brazil stands out for its high diversity of Orchidaceae, having in its flora about 220 genera and 2,500 species (BFG 2018). The taxonomic studies conducted in Bahia (Bastos & Van den Berg 2012;Marinho & Azevedo 2014;Vieira et al 2014), in Paraíba (Almeida et al 2007), in Pernambuco (Pessoa & Alves 2012, and in Sergipe (Pessoa & Alves 2011;Monteiro et al 2012) have helped improve is knowledge of Orchidaceae in the Northeast region of the country. However, some states such as Maranhão remain poorly studied from a taxonomic point of view, especially for this family, and only the list by is known.…”

Orchids of the central region of eastern Maranhão, Brazil

et al. 2021

The eastern portion of the state of Maranhão is a transitional area between Amazon Rainforest, Cerrado and Caatinga. Knowledge about the flora of this region is very poor, especially regarding Orchidaceae. The aim of this study was to provide a survey of the species of this family in the central area of this region. Fieldwork was performed monthly between December 2015 and April 2019 in the municipalities of Aldeias Altas, Caxias, Codó and São João do Sóter. An identification key, morphological descriptions and illustrations of the species are presented. Orchidaceae is represented in the area by seven genera and 17 species. The richest genera were Catasetum (five species), and Habenaria (four species). Habenaria schenckii is a new record for the state. The majority of the species are epiphytes (eight species, 47%) or terrestrial (seven species, 41%). The municipality of Caxias was the richest, with 13 species (76%), of which six were collected in the conservation units (CU’s) existing in the municipality (Área de Proteção Ambiental Municipal (APAM) Buriti do Meio Municipal and APAM Inhamum). Our data highlight the importance of the CU’s for the conservation of Orchidaceae, and the potential of ecotonal regions for discovering new records for the region.
