We describe and illustrate Paepalanthusserpens, a microendemic species of Eriocaulaceae from the Espinhaço Range. The species is known from a single population growing in rocky areas of the Serra do Cipó, Minas Gerais. It is placed in Paepalanthusser.Paepalanthus, and is easily distinguished from its congeneric species by its elongated, lignescent stem, thickened by the marcescent sheaths of the linear leaves, which are arranged in a rosette at the stem apex, scapes equalling the leaf height, and capitulae with straw-coloured involucral bracts. Comparisons with the morphologically similar species are provided, as well as comments on distribution, ecology, phenology and conservation status.
我们描述并展示了来自埃斯皮尼亚苏山脉的凤梨科微特有物种Paepalanthusserpens。该物种仅知分布于米纳斯吉拉斯州西波山岩石地区的一个种群。它被归入Paepalanthusser.Paepalanthus属，通过其细长的木质化茎很容易与同属其他物种区分开来，茎因线状叶枯萎的叶鞘而变粗，叶鞘在茎顶端呈莲座状排列，花葶与叶等高，头状花序具稻草色的总苞片。文中提供了与形态相似物种的比较，以及关于分布、生态、物候和保护状况的说明。
