The genus Populus has traditionally been divided into six sections on the basis of leaf and flower characters ; this classification is followed below.

The number of petals in a flower may hold clues to a plant's classification.

Before the availability of genetic evidence, the classification of angiosperms ( also known as flowering plants, Angiospermae, Anthophyta or Magnoliophyta ) was based on their morphology ( particularly of their flower ) and biochemistry ( the kinds of chemical compounds in the plant ).

All the foregoing rules and aids and difficulties in classification are explained, if I do not greatly deceive myself, on the view that the natural system is founded on descent with modification ; that the characters which naturalists consider as showing true affinity between any two or more species, are those which have been inherited from a common parent, and, in so far, all true classification is genealogical ; that community of descent is the hidden bond which naturalists have been unconsciously seeking, ...

This classification was based on several factors including interfertility, chromosome uniformity, chemotype, and numerical analysis of phenotypic characters.

Spore types can be used as taxonomic characters in the classification within the Ascomycota.

In 2009 John K. Tucker and Manuel J. Tenorio proposed a classification system for the cone shells and their allies ( which resorb their inner walls during growth ) was based upon a cladistical analysis of anatomical characters including the radular tooth, the morphology ( i. e., shell characters ), as well as an analysis of prior molecular phylogeny studies, all of which were used to construct phylogenetic trees.

Molecular genetic studies revealed, that the traditional classification, based on morphological and anatomical characters, often did not reflect the phylogenetical relationships.

" These " families " are a kind of classification for characters obtainable in the game, grouped mainly by appearance, though they are also associated with certain skills.

This anonymity may paradoxically enable the reader to identify with the characters as human, preventing the reader from observing racial characteristics based on facial traits, while reminding readers that racist classification is ever present.

The two friends wrote together five memoirs on natural history, one of which, on the classification of mammals, puts forward the idea of the subordination of characters upon which Cuvier based his zoological system.

In traditional Chinese character classification, the uncommon class of phonetic loan characters involved borrowing the character for one word to write another nearly homophonous word.

This classification into the three subgenera is based on cone, seed and leaf characters:

The classification of the boarfishes ( Caproidae ) in this order is uncertain, since they have many perciform characters, for instance in the caudal skeleton.

These works also possess a number of characters uniquely formed to express features not found in the classical language as well as used some common characters used as phonetic loans ( see Chinese character classification ) to express other uniquely Wu vocabulary.

Depending on the classification system and the characters considered, Canellaceae has been placed close to Annonaceae, Myristicaceae or Winteraceae.

The 2, 400 characters chosen as a result were arranged by classification on a character carriage, and the chosen character was raised by a type bar that could move forward and backward and left and right.

The two most advanced 19th century classifications both used complex skeletal characters ; Milne Edwards and Haime ’ s 1857 classification was based on macroscopic skeletal characters, while Ogilvie ’ s 1897 scheme was developed using observations of skeletal microstructures, with particular attention to the structure and pattern of the septal trabeculae.

Alloiteau ’ s 1952 classification built off of these earlier studies but included more microstructural observations and did not involve the anatomical characters of the polyp.
