摘要

哥伦比亚龙属(兰科)中有13种(18%)缺乏有关其生态学和生物地理学的基本信息。Dracula anthracina仍然是一种具有魅力的市场价值物种,没有关于其自然栖息地的信息。我们在哥伦比亚东部山脉的勘探中发现了D.蒽醌的确切位置。我们对野生种群和栽培植物的观察表明,根据形态特征,应将黑胸蛇简化为黑胸蛇的同义词。此外,这些物种似乎很少,地理上受到限制,种群很少。因此,我们建议D.蒽应被视为保护问题,并应被排除在厄瓜多尔植物群之外。摘要哥伦比亚龙属13种(18%)缺乏其生物地理学和生态学的基本信息。Dracula anthracin是一种具有很高市场价值的物种,其自然习性信息在历史上一直不为人所知。在探索哥伦比亚东部山脉的兰花时,我们发现了D.炭疽的位置。在研究了黑曲霉在其自然栖息地和栽培材料中个体的形态特征后,我们发现黑曲霉必须被还原为黑曲霉的同义词。我们的随机抽样表明,这种龙很少见,地理分布有限,种群很少。因此,D.炭疽作为一种商业化物种应被视为哥伦比亚特有的保护物种,并应被排除在厄瓜多尔植物群之外。

Circumscription, First Confirmed Locality, and Conservation Status of Dracula anthracina (Orchidaceae)
Abstract Thirteen species (18%) in the genus Dracula (Orchidaceae) in Colombia lack basic information about their ecology and biogeography. Dracula anthracina has remained as a charismatic market-valued species with no information on its natural habitat. We found the precise location of D. anthracina in explorations across the Colombian eastern Cordillera. Our observations of wild populations and cultivated plants suggest that D. nigritella should be reduced to a synonym of D. anthracina based on morphological characters. Furthermore, the species seems to be rare, geographically restricted, and has small populations. Hence, we suggest that D. anthracina should be considered of conservation concern and should be excluded from Ecuador's flora. Resumen Trece especies (18%) del género Dracula en Colombia carecen de información básica de su biogeográfica y ecológica. Dracula anthracina es una especie de alto valor en el mercado, cuya información del habito natural ha permanecido históricamente obscuro. Durante exploraciones de la orquideoflora de la cordillera oriental de Colombia, encontramos la ubicación de D. anthracina. Tras estudiar los caracteres morfológicos de individuos de D. anthracina en su hábitat natural y material cultivado, encontramos que D. nigritella debe ser reducido a sinónimo de D. anthracina. Nuestro muestreo aleatorio sugiere que esta Dracula es rara, con distribución geográfica restringida y poblaciones pequeñas. De tal manera, D. anthracina como especie comercializada debe ser considerada como una especie de conservación endémica de Colombia y debe ser excluida de la flora de Ecuador.
