Sinosasadamingshanensis (Poaceae, Bambusoideae), a new combination supported by morphological and molecular evidence.

Abstract

Morphological characteristics and phylogenetic analyses clearly revealed that Chimonobambusadamingshanensis should be a member of the genus Sinosasa, rather than Chimonobambusa, and is a distinct species close to Sinosasahuapingensis and S.mingyueshanensis. Morphologically, it differs from all the other known Sinosasa 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 Ch.damingshanensis as a new combination of Sinosasa.
