Crangquist quilt plant classification system

A. Cronquist, an American scholar, published his system in 1958 and revised it in 1968 and 1981. The outline is as follows: the bee plant door includes 11 sub-gangs, 83 eyes, 383 sections, 165,000 kinds of plants. Magnolia Gang (i.e. Geminal Leaf Plant): Contains 6 sub-gangs, 64 eyes, 318 sections. That is, Magnolia Yagang, Shizhu Yagang, Jin wisp Maya Gang, Rose Yagang, Wuyi Fruit Yagang, Ju Yagang. Lily outline (i.e. single leaf plant outline): including 5 sub-gang, 19 eyes, 65 sections of about 60,000 species of plants. Namely, Zetsya Gang, Penang Yagang, Duck Grass Yagang, Jiang Yagang, Lily Yagang. This system has a great influence in our country in recent years, the arrangement of classification system at all levels is more reasonable, the number and scope of sections are more moderate, which is conducive to teaching and use. In recent years, most of the teaching of plants in some botany textbooks in colleges and universities use this system.
