Trinomial nomenclature

For example: "Phalacrocorax carbo novaehollandiae (Stephens, 1826)" denotes a subspecies of the great cormorant (Phalacrocorax carbo) introduced by James Francis Stephens in 1826[1] under the subspecies name novaehollandiae ("of New Holland").For example, one might write: "The great cormorant Phalacrocorax carbo has a distinct subspecies in Australasia, the black shag P. c. novaehollandiae".This became the standard mainly because of tireless promotion by Elliott Coues – even though trinomina in the modern usage were pioneered in 1828 by Carl Friedrich Bruch and around 1850 were widely used especially by Hermann Schlegel and John Cassin.Thus, when referring especially European works of the preceding era, the nomenclature used is usually not in accord with contemporary standards.For algae, fungi, plants, and their fossils, there is an indeterminate number of infraspecific ranks allowed below the level of species.
