Li, a new species of <i>Gelidocalamus</i>, 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 <i>Gelidocalamus</i>. By using scanning electron microscopy (SEM), its leaf epidermal characters were observed in comparison with those of another three <i>Gelidocalamus</i> representatives. Our results show that the new taxon has the typical characteristics of the genus <i>Gelidocalamus</i>, both macromorphologically and micromorphologically. Moreover, it was most similar to <i>G.tessellatus</i>, but differed by a ring of white tomenta below per node, culm sheath base with PhytoKeys17-27https://www.ebi.ac.uk/biostudies/studies/S-EPMC10693675biostudies-literature<i>Gelidocalamusalbozonatus</i> (Poaceae, Bambusoideae), a new species from the southeast of Chongqing, China, and analysis of the morphological diversity in the core group of <i>Gelidocalamus</i>.PMC10693675Zhang WGZhang HJLi YLYi SRGuo RYang GYfalse<i>Gelidocalamusalbozonatus</i> (Poaceae, Bambusoideae), a new species from the southeast of Chongqing, China, and analysis of the morphological diversity in the core group of <i>Gelidocalamus</i>.<i>Gelidocalamusalbozonatus</i> W.
