根据染色体数目、匍匐茎分枝、性别表现、花粉形态及地理分布等，对草莓属的种类及其亲缘关系进行了讨论。可分为两类。一个欧亚-美洲类群，最初有六个二倍体物种，一个四倍体，一个六倍体和所有四倍体物种;一个东南亚-东亚类群，有四个二倍体物种，它们是四倍体物种的祖先。少数剩下的物种仍然不能隶属于这些群体之一。
Based on chromosome numbers, branching of stolons, sex expression, pollen morphology and the geographic distribution, the species of the genus Fragaria and their phylogeny are discussed. Two groups can be distinguished. A Eurasian-American group with originally six diploid species, one tetraploid, one hexaploid and all octoploid species and a Southeast-East Asian group with four diploid species which are ancestral to four tetraploid species. A few remaining species can still not be attached to one of these groups.
