Gelidocalamus zixingensis (Poaceae, Bambusoideae, Arundinarieae), a new species from southern China revealed by morphological and molecular evidence
Beschreibung:
<jats:p>The genus <jats:italic>Gelidocalamus</jats:italic> T. H. Wen, endemic to southern China, is a small but taxonomically problematic genus of Arundinarieae (Poaceae, Bambusoideae). During field work, a population of <jats:italic>Gelidocalamus</jats:italic> from Zixing, Hunan, was discovered, appearing to be distinct from our previously identified collection. Comparisons of the population of Zixing were performed by using scanning electron microscopy (SEM) and a plastid genome-based phylogeny. Morphologically, it was mostly similar to <jats:italic>G. multifolius</jats:italic>, but differed by culm leaf erect with densely white pubescence, apical branch sheath much longer than the internodes and foliage leaf larger. Phylogenetically, the new species was well-supported as a sister to the clade of <jats:italic>G. multifolius</jats:italic> + <jats:italic>G. tessellatus</jats:italic>, and the above three taxa were clustered in the <jats:italic>Shibataea</jats:italic> clade (IV) of Arundinarieae. Thus, the new species, formally named as <jats:italic>Gelidocalamus zixingensis</jats:italic> W.G.Zhang, G.Y.Yang & C.K.Wang, was described and illustrated herein.</jats:p>
