Abstract

Gelidocalamus albozonatus W. G. Zhang, S. R. Yi & Y. L. Li, a new species of Gelidocalamus, collected from Pengshui County of Chongqing City in China, was described and illustrated herein. In this study, key morphological characters were compared between the new species and other eight “gelido-” members of Gelidocalamus. By using scanning electron microscopy (SEM), its leaf epidermal characters were observed in comparison with those of another three Gelidocalamus representatives. Our results show that the new taxon has the typical characteristics of the genus Gelidocalamus, both macromorphologically and micromorphologically. Moreover, it was most similar to G. tessellatus, but differed by a ring of white tomenta below per node, culm sheath base with densely purple verrucous setae and foliage leaf blades mesophyll.
