Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), [Note 1] form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC.
Taxoboxes display the "taxonomic hierarchy". ("Taxon" is a general term for a named group of organisms, such as a subspecies, a species, a family, an order, etc.) The taxonomic hierarchy shows the location of the taxon within a particular classification system; e.g. for a genus, it may show its family, order, etc. up to kingdom.
Amborella trichopoda, the most basal extant angiosperm. The flowering plant family Amborellaceae, restricted to New Caledonia in the southwestern Pacific, [n 9] is a basal clade of extant angiosperms, [13] consisting of the most species, genus, family and order within the group that are sister to all other angiosperms (out of a total of about 250,000 angiosperm species).

Pleistoannelida is a group of annelid worms that comprises the vast majority of the diversity in phylum Annelida.Discovered through phylogenetic analyses, it is the largest clade of annelids, comprised by the last common ancestor of the highly diverse sister groups Errantia and Sedentaria (Clitellata and related polychaetes) and all the descendants of that ancestor.
For each major taxon you can add an unranked entry to the taxobox. The entry unranked X appears above rank X. String: deprecated: Superdomain: superdomain: This and other minor ranks should only be used when they are important to understanding the classification of the taxon described in the article.

In the lepospondyl hypothesis (LH), lissamphibians are the sister taxon of lysorophian lepospondyls, making lepospondyls tetrapods and temnospondyls stem-tetrapods. In the polyphyletic hypothesis (PH), frogs and salamanders evolved from dissorophoid temnospondyls while caecilians come out of microsaur lepospondyls, making both lepospondyls and ...
