菊科紫菀属广泛分布于北美洲和亚洲。Gray's Manual（Fernald，1950）收录紫菀属72种、49变种、36变型。根据北村的专著，我们在日本有23种，9亚种，13变种和4变型（北村，1937）。Tahara和Shimotomai（1926）首次报道了日本紫菀属的多倍体种。Shimotomai和Huziwara（1942）研究了紫菀属一些种的染色体形态，并将最大的核仁染色体命名为“L2 E-染色体”，具有次缢痕。裸子草属、马兰属和狗娃花属是东亚特有的植物。这三个属与紫菀属没有明显的区别，以前被认为是紫菀属的一部分。飞蓬属也与紫菀属密切相关。飞蓬属的成员主要分布在北美大陆。日本只有一种特有物种，即，E.英亩。然而，美洲的一些飞蓬属植物，如E. annuus和E.在几乎整个日本的田野和废弃地归化。一枝黄花属和一些小属，如Calculphus，Rhynchospermum，Lagenophora等也包括在亚洲紫菀属中。
The genus Aster of the family Compositae is of widespread occurrence in North America and in Asia. 72 species, 49 varieties and 36 forms of Aster are included in Gray's Manual (Fernald, 1950). According to Kitamura's monograph, we have in Japan 23 species, 9 subspecies, 13 varieties and 4 forms of this genus (Kitamura, 1937). Tahara and Shimotomai (1926) were the first to report polyploid species in Japanese Aster. Shimotomai and Huziwara (1942) studied the chromosome morphology of some species of Aster and gave the name "L2E-chromosome" for the largest nucleolar chromosome with a secondary constriction. Gymnaster, Kalimeris and Heteropappus are endemic to East Asia. These three genera are not sharply separated from the genus Aster and were formerly regarded as sections of Aster. The genus Erigercn is also closely related to the genus Aster. The members of Erigeron are mainly confined to the North American continent. Japan has only one endemic species, i.e., E. acre. However, some American species of Erigeron such as E. annuus and E. canadensis are naturalized in field and waste places over almost all of Japan. The genus Solidago and the small genera, Callistephus, Rhynchospermum, Lagenophora, etc. are also included in Asiatic Astereae.
