The taxa are aggregated at the predetermined set of nodes in the Taxonomy database that have been assigned “BLAST names”. This serves an informal, very abbreviated, vernacular classification that gives a convenient overview. The BLAST names will often not provide complete coverage for all species at all levels in the tree. Here, not all of our flowering plants are flagged as eudicots or monocots. The Common Tree summary display recognizes cases such as these and lists the remaining taxa as other flowering plants. The full Common Tree for some or all of the taxa can be seen by selecting the check box next to monocots on the summary page and then Choose. This will display the full Common Tree view for 108 families of monocots.
