摘要
彩藻属陆生一新种(Dumort.)Dumort。产于热带安第斯山脉北部的高海拔地区。该种与该属的其他成员在Oidocorys Jovet-Ast ex Grolle部分的不同之处在于其独特的超大的小叶和缩小的裂片，以及叶细胞的光滑表面。为南美洲北部提供了一个标识键。图中所描述的Colura stotleri sp. nov.是在海拔4700米的泥炭土壤中发现的，在高海拔地区缺乏合适的栖息地，突出了气候变化对山地植物保护的威胁。
A New Terrestrial Species of Colura (Marchantiophyta: Lejeuneaceae) at Tropical High Elevations (Boyacá, Colombia)
ABSTRACT A new terrestrial species of Colura (Dumort.) Dumort., from high elevations in the northern tropical Andes is described. The species differs from other members of the genus in the section Oidocorys Jovet-Ast ex Grolle on its unique oversized lobule and reduced lobe, and the smooth surface of the leaf cells. An identification key is provided for northern South America. Colura stotleri sp. nov., described here, is found at a single mountain top at 4700 m a.s.l. on peaty soil, with a lack of suitable habitats at higher elevations highlighting the threats posed by climate change on the conservation of mountain flora.
