摘要：

固沙草属(Orinus Hitchcock)为禾本科(Poaceae)、画眉草族(Eragrostideae)、三齿稃亚族(Tridentinae)的一个有重要经济价值的属,属内全部种类是优良牧草,并具有耐寒、耐旱、耐碱等特性,是农牧业良种繁育、畜牧业牧草改良利用的重要基因资源。该属在分类学上是一个疑难属,在属下类群划分及演化关系上问题较多。对固沙草属分类学问题进行了综述,为固沙草属植物资源的开发利用和保护提供资料。

Abstract:

Orinus Hitchcock is a genus with important economic value in Tridentinae (Poaceae: Eragrostideae). All of Orinus species are forage grasses for animal husbandry and used as important germplasm resources for grass breeding and improvement due to the characteristics of enduring cold, drought, and alkali. Many unresolved taxonomic questions are present in Orinus including the species delimitation and interspecific phylogenetic relationships. A taxonomic review of this genus is provided in order to accumulate background knowledge for further utilization of Orinus.

Key words: Poaceae, Eragrostideae, Tridentinae, Orinus, Taxonomy, Review
