Known as the "mother of gardens in the world", China has abundant plant germplasm resources (as many as 37,000 species of wild higher plants), but in recent years due to overutilization of resources, habitat destruction, invasion of alien species, environmental pollution, climate change and other factors, According to the "China Biodiversity Red List - Higher Plants Volume", there are currently about 3,767 species of wild plants in endangered or endangered status.
As the core backbone of ex situ conservation of plants, the South China National Botanical Garden currently protects 643 species of rare and endangered plants and 337 species of national key protected plants. Together with other botanical gardens and nature reserves, it constitutes China's rare and endangered plants. "Noah's Ark".
It is understood that 13 species of rare and endangered plants, including Ye Qihuamei's tiger face flower, the "Hemostatic Guard" golden retriever, the "Earth's only son" Putuo hornbeam, the "Land Lotus" summer lily, and the "eaves walk the wall" Danxia sycamore, are usually "hidden" in the unopened area - the breeding center for rare and endangered plants, and this exhibition is their first public exhibition.

It was previously found to be mainly distributed in Guangxi in China, and the type specimens were collected in Longzhou, Guangxi. It is also distributed in Myanmar, Thailand and the subtropical regions of our province. The oblique wing has high scientific research and medicinal value. Due to over-collection, the number of wild populations has been extremely scarce, and it has been listed as a national secondary key protected wild plant. South China National Botanical Garden has this kind of conservation.
