【 摘 要 】

Description and photos of main characters of Wiesnerella denudata (Mitt.) Steph. in Taiwan are provided. Sequence of chloroplast DNA rbcL and SEM photos of spores and elaters from Taiwan’s material are provided for the first time, which can be compared with materials from adjacent areas to show variation of the species. Three substitutions were found between plants of Taiwan and Nepal in rbcL sequences. Three morphological characters of spores are differentiated between the plants of Taiwan and mainland China. Spores are smaller in Taiwanese plant, 34-38 against 78.3-86.1 μm in diameter. Spore equatorial belt does not have any opening in Taiwan’s plant, but three openings are described in plant from mainland China. Exine is reticulate throughout the spore in Taiwanese plant, but it is restricted to the proximal surface of spore in plant from mainland China.
