In biology, a taxon (plural taxa; back-formation from taxonomy) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is not uncommon, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping.
Although preceded by Linnaeus's system in Systema Naturae (10th edition, 1758) and unpublished work by Bernard and Antoine Laurent de Jussieu, the notion of a unit-based "natural system" of biological classification was first made widely available in 1805 through the publication, as the introduction to the third edition of Jean-Baptiste Lamarck's Flore françoise, of Augustin Pyramus de Candolle's Principes élémentaires de botanique, an exposition of a system for the "natural classification" of plants. Since then, systematists have striven to construct an accurate classification encompassing the diversity of life; today, a "good" or "useful" taxon is commonly taken to be one that reflects evolutionary relationships.

(Phillips, Lee, Wagon)
I came home one night tuned my T.V. in
my favorite show was about to begin
as I was scanning across the dial
I saw her read the news with delectable style
Then I was sure that within a while
I was Stuck
Stuck in a pagoda
with Tricia Toyota
I¡¯m Stuck
We were watching Abe Vigoda
then every thing will be fine
Later that night we went for a drive
and I can say I never felt more alive
taking in the sights of old Tokyo
with Tricia by my side and money to blow
I knew then I never wanted to let her go
Chorus
Lead
Chorus
Always in a daze Always in a dream
Always find that things are not what they seem
A little Asian Goddess came from up above
I thank you NBC for sending my love
And Tricia is the one I've been dreaming of
Chorus
