摘要
本文论述了猪毛菜属系统分类的简史。依据该属的系统分类新资料,对我国猪毛菜属的分组系统作了进一步整理,将国产猪毛菜属植物归为6组5亚组。文中还讨论了该属的起源发生、迁移、分化以及地理分布等问题。
The paper is a report on the revised system of the genus Solsola L. byV. Botschantzev and certain problems of the origin, differentiation anddistributions of the genus Salsola. The genus Salsola L. comprising 27 species in northwestern deserts ofChina, is grouped into 6 sections: Sect. Caroxylon (Thunb.) Fenzl, Sect.Malpigipila Botsch., Sect. Cardiandra Aellen, Sect. Arbuscula Ulbrich,Sect. Coccosalsola Fenzl an Sect. Salsola. The most ancient section, Sect.Caroxylon is assumed to originate as early as in the Oligocene Miocene onSouth Africa. In the Pliocene it penetrated into the region of Red Sea andthe process of intense speciation occured there gave bosth the fruticosespecies of the sections Malpigipila, Belanthera, Arbuscula and Coccosalsola.Later in Asia, a new period of intense speciation resulted in the origin ofannual species of the above mentioned sections, as well as the sections Car-diandra and Salsola comprising only annual species.
