Sequencia [SEP] parent taxon
Sequencia
Sequencia is a monotypic genus of plants in the family Bromeliaceae. The sole species is Sequencia serrata (originally "Brocchinia serrata"), endemic to the Vaupés region of Colombia.
Formerly in the genus "Brocchinia", the genus was separated based on DNA sequence details (hence its name) and restriction site characteristics. Some authorities are accepting the altered taxonomy, while others are not.
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
