40 new plant species of the genus (Lasianthus Jack) were discovered from Vietnam

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.

In the work "A revision of the genus Lasianthus Jack (Rubiaceae) from Vietnam" the authors of the Institute of Tropical Biology of Vietnam Academy of Science and Technology and the Center for Tropical Biosphere Research of the University of the Ryukyus, Japan, have synthesized and described many new species and new records, bringing the total number of species of the genus Skunk in Vietnam to 73 species and 4 subspecies, of which there are 40 species and below Newly discovered and described species for science from Vietnam to the present, include:
