鹅观草属(Roegneria)属于禾本科小麦族,其物种都是含St与Y染色体组的异源多倍体植物.主要分布在亚洲,只有一个种分布于南欧,另一个种从亚洲一直分布到北美洲的阿拉斯加.由于St染色体组的显性遗传特性使含St染色体组的属,例如:Pseudoroegeria (St),Elymus (StH),Roegneria (StY)和Campeiostachys (HStY),在形态上表现出非常相似.更由于1984年Lve发表他划时代的以染色体组组成来界定的小麦族属的自然系统时还不知道Y染色体组的存在,因此他把鹅观草属合并到披碱草属(Elymus) 中,从而导致一些人至今仍然信奉他的系统而不承认鹅观草属.虽然现今对Y染色体组的研究已经取得巨大进步,所属物种也已十分清楚.其中当然也有传统的形态学分类对显性遗传造成的趋同熟视无睹带来的错误,以及一些大形态分类学家的错误分类的影响.现在发表的这个修订了的鹅观草属是基于形态观察、多变量形态统计分析、细胞遗传与分子遗传的研究成果综合判定的.这些成果来自不同的学者也包括我们自己.

The genus Roegneria belongs to the tribe Triticeae of the grass family Poaceae. The species of Roegneria are all allopolyploids with the St and Y genomes. Roegneria is mainly distributed in Asia and only one species grows in Southern Europe, and another extends to Alaska of North America. Most probably the dominance of the St genome is the cause for the morphological similarity among the species in the following genera, Pseudoroegeria (St), Elymus (StH), Roegneria (StY) and ompeiostachys (HStY). L(o)ve (1984) in his genomically based generic system of classification relegated Roegneria into Elymus, most likely because the Y genome in Roegneria plant was not well studied at that time. L(o)ve's influence combined with morphological resemblance were the main cause for taxonomists to keep these related genera together into Elymus. The present revision of Roegneria is a synthesis based on a combination of morphological observations, followed by multivariate morphometric analyses, cytogenetic and molecular genetic analyses.
