Abstract

W.C.Cheng did not clearly indicate the herbarium repository of the type specimen (Y.Tsiang 7712) when he described Tsuga longibracteata W.C.Cheng. Later, researchers suggested that the type is either in NAS or in PE. However, we found more than one duplicate of the type collection in both NAS and PE. Following the Shenzhen Code, we lectotypify the name T. longibracteata with Y.Tsiang 7712 (PE00003223) that bears a handwritten identification of W.C.Cheng.

Keywords: Nothotsuga; Pinaceae; Lectotype; Tsuga longibracteata; nomenclature.
