关于筇竹属和筇竹名称及命名模式的讨论

Discussion on the Name and Nomenclatural Type of the Genus of Qiongzhuea Hsueh et Yi and Qiongzhuea tumidinoda Hsueh et Yi

筇竹属(QiongzhueaHsueh et Yi)建立于1980年,模式种基于(Q.tumidinodaHsueh et Yi)。由于竹子是多年生植物,不是年年都开花结实,且一生只开一次花。我们当时考虑到竹子开花生物学的这种特点,以及为更方便准确鉴定该属及属以下种群,分别选用了王芳瑜、熊执权和杨开泰11563号有花、果枝标本和易同培73001号营养体标本作为(Q.tumidinodaHsueh et Yi)的共同模式。根据《国际植物命名法规》的相关条款规定,在命名一个新种或种以下新分类群时只能是一份标本。但当时法规(Leningrad Code,Art.7.5.1975;St.Louis Code,2000 and Vienna Code,Art.37.3.2006)明确规定有这种情况出现时,可以从它们之中选取后选模式(Art.7.5.)。有鉴于此,我们从发表时的两号标本之中选取王芳瑜、熊执权和杨开泰11563号有花、果枝标本作为筇竹的后选模式,使筇竹和筇竹属得到合格发表。

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 Interutional 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 and Q. lectotype of Qiongzhuea Hsueh et Yi between the two numbers , and genus of Q. tumidinoda Hsueh et Yi tumidinoda Hsueh et Yi can be published validly.
