摘要

摘要描述了巴西东北部巴伊亚州Miguel Calmon和Jacobina市的Chapada Diamantina特有的隐花属(Cryptanthus)新种。隐花的特征是叶片边缘带红色，近基部有白色鳞片，向先端正面无毛，背面被毛状体覆盖，毛状体掩盖了叶子的颜色。比较了两个相似的物种，C. reisii和C. bibarrensis，被认为是密切相关的。研究发现，蜂群曾访花并采集花瓣上的花精，这一关系为该新种的命名奠定了基础。根据世界自然保护联盟(IUCN)制定的标准，以860平方公里的发生范围和1000平方公里的占用面积为基础，将其列为濒危物种(EN)。

Cryptanthus euglossinii (Bromeliaceae: Bromelioideae), a new species from Chapada Diamantina, Bahia

Abstract A new species of Cryptanthus, known exclusively from Chapada Diamantina, in the municipalities of Miguel Calmon and Jacobina, state of Bahia, Northeast Brazil, is described and illustrated. Cryptanthus euglossinii is characterized by having leaves that are reddish in the marginal region, white-scaly near the base and glabrous adaxially towards the apex, with the abaxial surface covered by trichomes that obscure the color of the leaf. Comparisons are made with two similar species, C. reisii and C. bibarrensis, that are considered closely related. Euglossinii bees were observed visiting the flowers of C. euglossinii and collecting floral essences on petals, a relationship that is the basis of the epithet of the new species. Cryptanthus euglossinii is considered Endangered (EN) based on an extent of occurrence of 860 km2, an area of occupancy of 1,000 km2, and criteria established by the IUCN.
