Abstract

Two new species of Chlorospatha (section Orientales) from the western slope of the Cordillera Occidental in the departments of Valle del Cauca and Choco (Colombia) are described here. The new species represent the first records of section Orientales for Colombia, which was previously known only from the eastern Andes in Ecuador. The two new species are similar to , and . . is differentiated by its small overall size (less than 30 cm tall), blade strongly inequilateral with smooth adaxial surface, and spadix less than 2.2 cm long. . is differentiated by its large overall size (30-60 cm tall), 1-3 leaves per plant, and quilted adaxial blade surface.

摘要

本文描述了来自哥伦比亚考卡山谷省和乔科省西科迪勒拉山西坡的两种新的绿叶仙茅属（东方组）植物。这两个新物种是哥伦比亚东方组的首次记录，该组此前仅在厄瓜多尔的东安第斯山脉有记载。这两个新物种与……相似。……的区别在于其整体尺寸较小（植株高度不到30厘米），叶片强烈不等侧，正面光滑，肉穗花序长度不到2.2厘米。……的区别在于其整体尺寸较大（植株高度30 - 60厘米），每株有1 - 3片叶子，叶片正面呈绗缝状。
