悬钩子属植物隶属于蔷薇科蔷薇亚科悬钩子族，广布于除南极以外的全球各地，具有重要的资源价值和生态意义。中国是悬钩子属资源最为丰富的地区之一。尽管《中国植物志》，《Flora of China》和地方植物志的相关卷册大多已经出版，但到目前为止悬钩子属的经典分类学研究仍不充分，许多分类学问题尚未解决。空心莓亚属为悬钩子属最大的亚属之一，全亚属含110余种，其中约88种产于中国。本研究以国产空心莓亚属植物为研究对象，拟采用经典的形态地理学研究方法，通过文献考证、标本查阅、野外居群调查和微形态学研究，结合生态和地理分布资料对其进行全面的分类学修订，旨在解决空心莓亚属的物种划分的这一核心问题，并弄清其种类与分布,澄清长期以来的分类混乱。

The genus Rubus, belonging to the monotypic tribe Rubeae of the subfamily Rosoideae in Rosaceae，occurs in all continents except Antarctica. Species of Rubus usually have high resource and ecology values. China possesses a rich set of species of Rubus L. and is the distribution and diversity centers of R. subg. Malachobatus and R. subg. Idaeobatus. Although Flora Reipublicae Popularis Sinicae，Flora of China and other regional floras had finished，there are still numerous unresolved issues on the taxonomy of Chinese bramble. R. subg.Idaeobatus is one of the largest subgenera and approximately consists of 110 species, and about 88 of them are found in China. The subgenus Idaeobatus in China will be taxonomically revised based on morphological and phytogeographical patterns in this study. This study aims to solve the species-delimitation criteria of R. subg. Idaeobatus and to clarify its classification and distribution. The morphological comparisons will be based on observations of wild populations and specimens in herbaria;the nomenclature of R. subg.Idaeobatus will be revised based on relevant literature and Melbourne Code; and the micromorphological features will also be carried out.
