Taxonomic re-evaluation of some Gelidocalamus (Poaceae: Bambusoideae) taxa from Southeast China

In the present study, we employed a classical taxonomic analysis of micromorphological characters of the leaf epidermis to reassess the taxonomy of four Gelidocalamus taxa, a genus of woody bamboos endemic to China. We propose that G. subsolidus is distinct from G. tessellatus, and G. albopubescens should be placed in synonymy under G. subsolidus. A formal taxonomic treatment is presented, including description, comments, illustrations, a distribution map, and SEM images of the abaxial leaf epidermis.
