The neotropical genus Ruiz & Pav. ex J.St.-Hil. (Ericaceae), comprises about 70-75 species and is distributed from Honduras in Central America, through the central Andes south to Bolivia, and eastward to Suriname and Brazil in South America. Ecuador is one of the countries with the greatest diversity of the genus, including 18 species, 12 of which are endemic. Within southeastern Ecuador, the Cordillera del Cóndor is a region characterized by exceptionally high levels of plant endemism, largely due to its unique geology. Recent botanical explorations across this area have led to the discovery of several new species in recent years. Among those was a peculiar species of that is distinct by having exclusively cauliflorous inflorescences in which the pedicel is articulated with the calyx and the filaments are connate. This species is here described and illustrated as
A new species, , is described from the Cordillera del Cóndor in eastern Ecuador. It is distinguished by having a scrambling habit, provided with lignotubers, lanceolate leaves that are verticillate at the apex of branches, solitary and glabrous flowers, caducous bracts and bracteoles, stamens shorter than the corolla, anthers with prognathous thecae, and laterally connate tubules. The taxonomic similarities of the new species are discussed, and information about its distribution, habitat, and conservation is provided.
新热带属Ruiz & Pav. ex J.St.-Hil.（杜鹃花科）包含约70 - 75个物种，分布于中美洲的洪都拉斯，经安第斯山脉中部向南至玻利维亚，向东至南美洲的苏里南和巴西。厄瓜多尔是该属物种多样性最高的国家之一，有18个物种，其中12个为特有种。在厄瓜多尔东南部，孔多尔山脉是一个植物特有性极高的地区，主要因其独特的地质构造。近年来，对该地区的植物学探索发现了几个新物种。其中有一个奇特的物种，其独特之处在于仅具茎花状花序，花梗与花萼相连，花丝合生。在此对该物种进行描述和图示。
一种新物种， ，从厄瓜多尔东部的孔多尔山脉被描述。它的特点是具有攀缘习性，有木质块茎，披针形叶子在枝条顶端轮生，单生且无毛的花，早落的苞片和小苞片，雄蕊短于花冠，花药具前伸的药室，以及侧向合生的小管。讨论了新物种的分类相似性，并提供了其分布、栖息地和保护方面的信息。
