Abstract: The Genus of Qiongzhuea Hsueh et Yi was established in 1980. Its type species was based on Q. tumidinoda Hsueh et Yi. Because bamboo is perennial plant, does not flower and fruit every year and it has only a florescence in life. At that time, we considered the property of biology on bamboo flowering, and in order to identify the Qiongzhuea taxon of its infragenus and its species more easily and exactly, we selected specimens with flower and fruit branch of Wang Fangyu, Xiong Zhiquan and Yang Kaitai 11563 and vegetagive of Yi Tongpei 73001 as common syntypes of Q. tumidinoda Hsueh et Yi. According to the relative rules in the Interntional Code of Batanical Nomenclature (Tokyo Code, 1994. Art. 8.1.), only one specimen can be selected when naming a new species or infraspecific taxon, however, in this case stipulated definitely in Leningrad Code, Art. 7. 5.1975; St. Louis Code, 2000 and Vienna Code, Art. 37.3. 2006, lectotype may be selected among them. So we select specimen with flower and fruit branch of Wang Fangyu, Xiong Zhiquan and Yang Kaitai 11563(fl. fr.) as lectotype of Qiongzhuea Hsueh et Yi between the two numbers , and genus of Q. tumidinoda Hsueh et Yi and Q. tumidinoda Hsueh et Yi can be published validly.
