The plants of Actinidia are of great economic importance. And the taxonomy of Actinidia was very difficult and confusing. The genus Actinidia was established by Lindley in 1836 based on the specimen Wallich 6634 collected by N. Wallich in Nepal in 1821. Comprehensive studied on the taxonomy of the genus were carried out by Dunn, H. L. Li, and C. F. Liang.

猕猴桃属植物具有极大的经济价值，而且该属是分类上极其困难的属之一。1836年英国植物学家John Lindley根据Nathaniel Wallich 1821年在尼泊尔采集的标本Wallich 6634号建立了Actinidia即猕猴桃属，Dunn和李惠林及梁畴芬曾对该属进行过全面的研究。
