Sinosasa damingshanensis (Poaceae, Bambusoideae), a new combination supported by morphological and molecular evidence

Morphological characteristics and phylogenetic analyses clearly revealed that <i>Chimonobambusadamingshanensis</i> should be a member of the genus <i>Sinosasa</i>, rather than <i>Chimonobambusa</i>, and is a distinct species close to <i>Sinosasahuapingensis</i> and <i>S.mingyueshanensis</i>. Morphologically, it differs from all the other known <i>Sinosasa</i> species by internodes initially with white pubescent, culm leaf auricles absent and triangularly subulate sheath blades, characteristics that are unusual in this genus. And this morphological distinction warrants recognition of <i>Ch.damingshanensis</i> as a new combination of <i>Sinosasa</i>.
