Abstract

ABSTRACT The Brazilian Amazon encompasses about 29% of the orchid species in Brazil. With the aim of contributing to the knowledge of the Amazonian flora, a taxonomic study of Orchidaceae was carried out in a forest fragment in the municipality of Capitão Poço, located in the Belém Endemism Center, the most deforested area in the Amazon. The fragment is locally referred to as Reserva São Geraldo Majela (RSGM) and is entirely surrounded by agricultural lands. Specimens were collected from February 2020 to April 2022 and deposited in the HCP herbarium, the analysis being complemented by consulting the collections of relevant herbaria. We provide descriptions and an identification key for the eight species of Orchidaceae recorded in RSGM, all of them showing a wide geographic distribution. Seven of them are epiphytes: Campylocentrum fasciola, Campylocentrum micranthum, Catasetum macrocarpum, Erycina pusilla, Notylia lyrata, Polystachya concreta, Rodriguezia lanceolata; and one is terrestrial: Oeceoclades maculata. These findings represent 65% of the previously recorded orchid species for the municipality of Capitão Poço and reinforce the importance of conserving the forest remnants in the region.

巴西亚马逊河流域帕拉州贝伦特有物种中心 São Geraldo Majela 保护区的兰科植物

巴西亚马逊地区拥有巴西约29%的兰花种类。为了促进对亚马逊植物区系的了解，在位于亚马逊森林砍伐最严重的bel姆地方主义中心的首都 o poo市的一片森林中对兰科植物进行了分类研究。这个片段在当地被称为Reserva s o Geraldo Majela (RSGM)，完全被农业用地包围。标本于2020年2月至2022年4月收集，并存放于HCP植物标本室，并通过查阅相关植物标本室的藏品来补充分析。我们提供了8种兰科植物的描述和鉴定密钥，它们都显示出广泛的地理分布。其中7种为附生植物:片形弯曲菌、微弯曲菌、大弯曲菌、赤藓菌、野苔菌、水杨菌、水杨菌、杉木菌;另一种是陆生的:斑纹蛙。这些发现代表了capitapo poo市以前记录的兰花物种的65%，并加强了保护该地区森林遗迹的重要性。
