There are more than 1,300 genera and nearly 220,000 species in 13 families, and they are distributed worldwide except Antarctica. Due to the various characteristics of the family in structure and reproduction, such as sepals becoming crown hairs and spiny hairs, it is conducive to the long-distance dispersal of fruits; Some species have tubers, roots, stolons or rhizomes, which are conducive to vegetative reproduction. In addition, the structure of the inflorescence and the high degree of adaptation to insect pollination have prompted its rapid development and differentiation, so that it has reached the highest number of genera, species and individuals among angiosperms.

There are about 220 genera and nearly 3,000 species in China, which are distributed throughout the country, among which 15 genera are endemic to China, including Heterophyllum spp., Miscanthus spp., Taihang Spp., Brush Spp., Heavy Feather Spp., Yellow Tassel Spp., Chuanmuxiang Spp., Bolocephalus, S.
