Here are 42 Flowering Plant Families  arranged in evolutionary order, 8 Monocots and 34 Eudicots. 


Angiosperms families are arranged according to the linear sequences published by the Angiosperm Phylogeny Group APG (Haston et al. in 2009, updated in 2016). Botanical institutions organize their collections in linear sequences that reflect evolutionary relationships, rather than arranging them alphabetically. Various linear sequences have been proposed over the years but these sequences, based increasingly on DNA analysis, are now considered to be the most reliable. The table shows that some families are closely related and placed in the taxonomic level Order. For example Poppy and Buttercup families are in the Order Ranunculales. The scientific names of Orders generally end in -ales. 

The APG propose the word Clade and Superorder to show larger evolutionary groupings of families. Clades and Superorders are words used to define monophyletic groups i.e groups of organisms that consist of all the descendants of a common ancestor.
