柽柳科红砂属植物种类在我国的分布虽然不多,但属的种类可形成亚洲干旱区荒漠地带的建群种或优势种。目前尚无分类专著和系统的分类研究。根据世界各地植物志和国内标本馆信息,对世界红砂属的分类和分布进行了系统的整理。确认红砂属含21种,隶属2亚属2组6系,我国仅4种。该属是中亚干旱区集中分布的一个属,有18种之多,但也延伸到西亚、南欧、北非等地。在亚属、组、系的分类等级上,对其分布进行了分布点图的标记,并对中国分布的4种红砂也进行了标记。
Reaumuria L. is a small genus with only 4 species in China, however, the species of this genus can be served as the constructive species and/or the dominant role in vegetation in arid Central Asian desert zone. There is no a monograph for this genus in the world yet. Based on the floras of China, former USSR, Iran and Europe as well as the information of herbaria in China, a classification and distribution is contributed comprehensively in this paper. There are 21 species belonging to two subgenera, two sections and six series, and four species in China in Reaumuria to be recognized. The distribution at the levels of subgenus, section, series and four species in China are illustrated. The distribution center of this genus is located in Central Asia where 18 species are included, but a few species can stretch to western Asia, southern Europe and northern Africa.
