, a new species from Buenaventura Reserve at El Oro province in Ecuador is described and illustrated. Additionally, notes on its geographical distribution, ecology, conservation status, and taxonomic affinities are documented. has some vegetative and floral similarities with other Andean species, but the unique combination of oblong-lanceolate leaves with prominent secondary and tertiary veins, densiflorous floriferous shoots less than 5 cm long, sepals with two marginal glands and flowers with turbinate hypanthium clearly differentiates it from the rest. This is the first species of described from the western flank at elevation below 1500 m, and particularly from a humid spot surrounded by dry areas (Tumbesian influence). Other taxonomic novelties of on this flank can be expected, so further botanical exploration is needed to better understand the diversity of the genus in the region.
描述并图示了来自厄瓜多尔埃尔奥罗省布埃纳文图拉保护区的一个新物种。此外，记录了其地理分布、生态、保护状况和分类亲缘关系的相关说明。该物种与其他安第斯物种在营养体和花部有一些相似之处，但长圆状披针形叶片具明显的二级和三级叶脉、长度小于5厘米的密集花状嫩枝、具两个边缘腺体的萼片以及具陀螺形托杯的花的独特组合使其明显区别于其他物种。这是首次在海拔1500米以下的西侧描述该属的物种，特别是来自一个被干旱地区包围（通贝斯影响）的潮湿地点。预计在该侧翼还会有该属的其他分类新发现，因此需要进一步的植物学探索以更好地了解该地区该属的多样性。
