Abstract： With the intensification of human activities and global climate change, biological species loss has being rapidly accelerated. Ex situ conservation of plants is a crucial approach for preserving plant diversity and will play a central role in the establishment of the National Botanical Garden System of China. However, issues regarding the concept and range of the ex situ conservation of plants, and China’s rare and endangered plants, as well as the goals for ex situ conservation of plants in China, are still under discussions. Thus, the concept of the ex situ conservation of plants, the scope of the China’s rare and endangered plants, the differences between the threatened plants in China Red List of Biodiversity, the National Key Protected Wild Plants of China and the Plant Species with Extremely Small Populations (PSESP), as well as the specific targets for China’s ex situ conservation of plants have been thoroughly discussed and clarified in this paper. In addition, three issues related to China’s ex situ conservation of plants are examined and also the specific suggestions are proposed, including the effectiveness of ex situ conservation of plants, the documentation of plant collection, introduction and conservation information, as well as the development and management of National Botanical Gardens of China. This review provides a theoretical basis for the ex situ conservation of plants in China.

Abstract： Biodiversity conservation is one of the hottest topics at present all over the world. In order to rescue the most threatened plant species in the wild, to guide the China’s biodiversity conservation and to serve the construction of national ecological civilization, a new concept of plant species with extremely small populations (PSESP) was proposed in China, which is attracting the widespread attention internationally in plant species conservation. In the past 13th Five-Year Plan period, China launched the comprehensive program for rescuing and conserving PSESP. And now, in the coming 14th Five-Year Plan for National Economic and Social Development and the Long-term Targets for 2035 of the People’s Republic of China, the rescue of PSESP is explicitly incorporated into the special aims at the conservation of important ecosystem and ecological restoration. The PSESP rescue and protection is a long-term systematic work with strong science, high technical and professional requirements. For scientifically conserving PSESP, rescue protection and system study should be given an equal weight. Undoubtedly, systematic research on the PSESP conservation is an important task to support their effective conservation. This paper is trying to systematically review the recent research works on the PSESP conservation, focusing on the surveys and assessment of the current population or individual status (including confirmation of species taxonomic status), eco-biological characteristics, propagation techniques and genetic diversity, with the aim to find new theories and to form new ideas for the conservation of PSESP. Finally, three insights into priorities for future conservation research of PSESP in China are proposed, which could be a reference to systematic research on the further PSESP conservation.
