The title of Asteraceae "Index to Chromosome numbers in Asteraceae" has been used for the representative of families in Asterales due to the largest and most familiar for many researchers. It is included the published data of all members in whole of Asterales, instead of being restricted to just members of Asteraceae: Alangiaceae, Alseuosmiaceae, Argophyllaceae, Calyceraceae, Campanulaceae, Carpodetaceae, Goodeniaceae, Menyanthaceae, Pentaphragmataceae, Phellinaceae, Rousseaceae, Stylidiaceae (all of them are placed in Asterales at present "2021, December""). This Database includes taxon name, chromosome number (n and 2n), DNA contents, genbank accession numbers (for the nuclear or chloroplast DNA sequences:You can know that taxa used for molecular phylogenetic analyses), habit (life form) and size of plant, reproductive system, collection locality (Nation), Author (s) and the title of paper and published journal names.
The classification of the Asteraceae (= Compositae) follows on Susanna, A. et al (2020) is followed in this database.
