摘要
概述了早竹学名变动的历史沿革,支持将Phyllostachys violascens(Carr.)A.et C.Riv.作为早竹的正确学名,而将Ph.praecox C.D.Chu et C.S.Chao减为其异名的分类学处理结果。通过文献考证和实物照片比较分析认为,在国产早竹复合体中,产于浙皖毗连地区的新秆深绿带紫色、密被白粉、节部紫色,老秆灰绿色或黄绿色并有暗黄色或淡褐色纵条纹,其土名称之为"土早竹"(也称"宽叶早竹")这一类型与Ph.violascens(Carr.)A.et C.Riv原植物相符。而Ph.praecox C.D.Chu et C.s.Chao模式植株则为栽培品种"余杭早竹",但其原发表时的营养器官形态描述中混有"土早竹"的特征。随着近20余年来"土早竹"资源的锐减,应加强其保护。
The historical changes of scientific name of Zaozhu are summarized.A result of taxonomic treatment,proposing Phyllostachys violascens（Carr.） A.et C.Riv.as correct scientific name of Zaozhu and reducing Ph.praecox C.D.Chu et C.S.Chao into its synonym,is supported by the present author.In Zaozhu complex from China, ＂Tu Zaozhu＂（also as ＂Kuanye Zaozhu＂）,a local name from contiguous area of Zhejiang and Anhui and with dark-green and dense-pruinose young culms,purplish culme-nodes,and grey-green or yellow-green old culms notated with luteotestaceous-or brownish-stripes,is recognized to be good consistent with the original plant of Ph.violascens（Carr.） A.et C.Riv.in morphology.The typical plants of Ph.praecox C.D.Chu et C.S.Chao can be identificated as a cultivar ＂Yuhang Zaozhu＂（Ph.violascens（Carr.） A.et C.Riv.＇Praecox＇）,which is mixed by some characters of ＂Tu Zaozhu＂ in original description.With the decrease of the resources in recent 20 years, ＂Tu Zaozhu＂ should be further protected.
