E The team of Dr. Chen Hesheng of the Plant Center of the South China Botanical Garden of the Chinese Academy of Sciences published a new genus of chrysanthemum, li Hengju genus
. The family name commemorates Professor Li Heng, who made an important contribution to the study of the plants of Mount Goligon. The study was published recently in Plant Classification.
is one of the largest plant groups in the world, more than 30,000 species, but also the largest plant in China, with more than 2400 species. The thick chrysanthemum genus is a genus of about 15 species, all of which are distributed in the Pan-Himalaya region and its adjacent areas. Stebbins, an American botanist and geneticist, once thought that the thick chrysanthemum genus had some widely distributed ancestral groups of chrysanthemums.
combined cytological and morphological evidence, the researchers combined to find that the genus thick chrysanthemum is not a natural monogenic group. The number of chromosomes of most species of the genus is 2n-16, located in the Yayang ginseng sub-species, but there are two species with blue flowers chromosome number 2n-18, located in the Yi sub-family.
Chen also introduced, brown hair thick chrysanthemum (now "Li Hengju"), short thick chrysanthemum (now "dwarf Li Hengju") two species are mainly distributed in the Gaoligong Mountain area, for perennia near stemless herbs, leaves all the base, flower blue, thin fruit column and has no obvious ribs, crown brown, is a unique group. Based on sufficient evidence, Chen's team published a new genus, Li Hengju. (Source: Zhu Hanbin Zhoufei, China Science Journal)
