Lasianthus (Lasianthus Jack) is a large genus of the Coffee family (Rubiaceae) with more than 180 species, distributed mainly in Asia, with a few in Africa, America and Australia. In Vietnam, according to statistics of Pham Hoang Ho (2000), the genus Xu Xu has about 28 species and 4 species. Since then, scientists from the Institute of Tropical Biology under Vietnam Academy of Science and Technology together with domestic and international partners have discovered, described and announced many new species of the genus. This increased the number of species of the genus Safflower to more than double compared to the previous one.
