Ranunculus auricomus Ranunculidae is a subclass of plants used in some taxonomic systems and not others. By necessity it includes the order Ranunculales, but otherwise it differs between taxonomic systems.

Iteaceae is a flowering plant family of trees and shrubs native to the eastern USA, southeastern Africa, and south and Southeastern Asia. Some older taxonomic systems place the genera in this family in the Grossulariaceae. The APG III system of 2009 includes the former Pterostemonaceae in Iteaceae. Consequently it now has two genera with a total of 18 known species.

Cavalier-Smith's system was developed before the presence and function of mitochondria in life forms was well-codified into taxonomic systems. As the understanding of the functions of mitochondria became more advanced, phylogeny of these life forms became more nuanced. At various times, a few life forms were included in Archezoa. Two groupings of protists- Pelobionts and entamoebids (now Archamoebae)- were included.

Linnaeus's Systema Naturae, Leiden, 1735 This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A taxonomic system is a coherent whole of taxonomic judgments on circumscription and placement of the considered taxa. It is only a "system" if it is applied to a large group of such taxa (for example, all the flowering plants). There are two main criteria for this list.

In the Tholen classification as well as in the lesser known taxonomic method by Howell, Ara is a metallic M-type asteroid. This spectral type translates into the X-type in more modern asteroid taxonomic systems. In 2018 and 2019, a study using photometry from the Korea Microlensing Telescope Network and the South African Astronomical Observatory, grouped Ara into the X-type category based on the Bus–DeMeo classification.

Pterostemonaceae (Engl.) Small is a small family of shrubs native to tropical and subtropical Mexico. The family was recognized by scientists working with the Angiosperm Phylogeny Group but is placed in the Grossulariaceae by other taxonomic systems. The APG II system recognized the family as containing a single genus, Pterostemon. The APG III system of 2009, and later versions, do not recognize this family and place Pterostemon within the Iteaceae in the order Saxifragales.

Simmondsiaceae or the jojoba family is a family of flowering plants. The family is not recognized by all taxonomic systems, the single species, Simmondsia chinensis, often being treated as belonging to family Buxaceae. The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family and assigns it to the order Caryophyllales in the clade core eudicots. It consist of a single species only, jojoba (Simmondsia chinensis), of North American shrubs.

The structure and development of mosses and ferns (Archegoniatae). 2nd ed. 1905 In the major post-Darwinian taxonomic systems such as the Engler system it was used to divide the Embryophyta into two divisions, one the Archegoniatae (also called Zoidogamae) containing bryophytes and pteridophytes and the other the Siphonogamae containing the gymnosperms and angiosperms. Campbell indicates that there was both a sensu lato usage which included the gymnosperms, or a sensu stricto usage as in his book, applied only to bryophtes and pteridophytes.

The amaryllis family has been recognized in many taxonomic systems, but the limits of the family have varied. In the narrowest definition, the Amaryllidaceae sensu stricto is characterized by an umbellate inflorescence with an inferior ovary. Two other groups have similar inflorescences but a superior ovary, and have at times been put into separate families: the Agapanthaceae and the Alliaceae. Based on phylogenetic research, the latest (2009) revision of the APG classification groups together these three families under the conserved name of Amaryllidaceae.

When the Angiosperm Phylogeny Group published the APG II system in 2003, Themidaceae was accepted as an optional family for those who wanted to circumscribe families narrowly in the order Asparagales. When the APG III system was published in 2009, the former Themidaceae was treated as a subfamily, Brodiaeoideae, of the family Asparagaceae sensu lato. Some sources, such as ITIS, continue to use the polyphyletic groups of obsolete taxonomic systems. Other sources, such as the Angiosperm Phylogeny Website mostly follow the Angiosperm Phylogeny Group.

The 18th century saw some early systems, which are perhaps precursors rather than full taxonomic systems. A milestone event was the publication of Species Plantarum by Linnaeus which serves as the starting point of binomial nomenclature for plants. By its size this would qualify to be on this list, but it does not deal with relationships, beyond assigning plants into genera. Note that a system is not necessarily monolithic and often goes through several stages of development, resulting in several versions of the same system.

Berlin, Breedlove and Raven began to encourage and emphasize the importance in gaining ethnobiological information regarding nomenclature and utilizing the principles they laid out to increase our knowledge of potentially general cognitive categorizing, the people who use these taxonomic systems, and how these systems can influence our view of the environment around us. In a following article published in the American Ethnologist (1976),Berlin, B. (1976). The concept of rank in ethnobiological classification: some evidence from Aguaruna folk botany. American Ethnologist, 3(3), 381-399.

An asteroid spectral type is assigned to asteroids based on their emission spectrum, color, and sometimes albedo. These types are thought to correspond to an asteroid's surface composition. For small bodies that are not internally differentiated, the surface and internal compositions are presumably similar, while large bodies such as Ceres and Vesta are known to have internal structure. Over the years, there has been a number of surveys that resulted in a set of different taxonomic systems such as the Tholen, SMASS and Bus–DeMeo classification.

The taxonomy of the Liliaceae has a very complex history. The family was first described in the eighteenth century, and over time many other genera were added until it became one of the largest of the monocotyledon families, and also extremely diverse. Modern taxonomic systems, such as the APG which is based on phylogenetic principles using molecular biology, have redistributed many of these genera resulting in the relatively small family that is currently recognised. Consequently, there are many different accounts of the Liliaceae in the literature and older uses of the term occur commonly.

Baker had placed the two species of Galtonia, which at that time he considered to be Hyacinthus in the tribe Hyacintheae, one of eight tribes that he divided the Liliaceae into. Later in the 1880s, Galtonia with its two species was included as a district and separate genus in two influential taxonomic systems. In the United Kingdom Bentham and Hooker published their volume on the Liliaceae in Latin in 1883. Bentham and Hooker divided it into 20 tribes and placed Galtonia in the tribe Scilleae with 19 other genera.

The term ethnotaxonomy refers either to that subdiscipline within ethnology which studies the taxonomic systems defined and used by individual ethnic groups, or to the operative individual taxonomy itself, which is the object of the ethnologist's immediate study. For example, in many West African languages, the perceptual world of color is classified into the principal categories "Red," "White," and "Black" (finer gradations being secondary). The range of wavelengths that an English-speaker calls blue would be a subcategory of "Black." The set of categories of familial relationships evinced by the ethnic group's kinship system is another ethnotaxonomy.

Lyric poetry, once considered non-mimetic, was deemed to imitate feelings, becoming the third "Architext", a term coined by Gennette, of a new long-enduring tripartite system: lyrical; epical, the mixed narrative; and dramatic, the dialogue. This new system that came to "dominate all the literary theory of German romanticism" (Genette 38) has seen numerous attempts at expansion and revision. Such attempts include Friedrich Schlegel's triad of subjective form, the lyric; objective form, the dramatic; and subjective-objective form, the epic. However, more ambitious efforts to expand the tripartite system resulted in new taxonomic systems of increasing complexity.

Mussels in the intertidal zone in Cornwall, England Mytilarca is a distant relative of the mussels; from the Middle Devonian of Wisconsin. Fossil gastropod and attached mytilid bivalves in a Jurassic limestone (Matmor Formation) in southern Israel Aviculopecten subcardiformis; a fossil of an extinct scallop from the Logan Formation of Wooster, Ohio (external mold) For the past two centuries no consensus has existed on bivalve phylogeny from the many classifications developed. In earlier taxonomic systems, experts used a single characteristic feature for their classifications, choosing among shell morphology, hinge type or gill type. Conflicting naming schemes proliferated due to these taxonomies based on single organ systems.

Only since the more modern taxonomic systems developed by the Angiosperm Phylogeny Group (APG) and based on phylogenetic principles, has it been possible to identify the many separate taxonomic groupings within the original family and redistribute them, leaving a relatively small core as the modern family Liliaceae, with fifteen genera and 600 species. The Liliaceae emerged from the Liliales order, separating from its sister clade around 52 million years ago (mya), and diversifying around 34 mya. Of the major clades, the Lilieae arose in Eurasia while the Medeoleae arose in North America but was subsequently dispersed, as may have the Streptopoideae and Calochortoideae. Liliaceae fossils have been dated to the Paleogene and Cretaceous eras in the Antarctic.

Lyric poetry, once considered non- mimetic, was deemed to imitate feelings, becoming the third leg of a new tripartite system: lyrical, epical, and dramatic dialogue. This system, which came to "dominate all the literary theory of German romanticism (and therefore well beyond)…" (38), has seen numerous attempts at expansion or revision. However, more ambitious efforts to expand the tripartite system resulted in new taxonomic systems of increasing scope and complexity. Genette reflects upon these various systems, comparing them to the original tripartite arrangement: "its structure is somewhat superior to…those that have come after, fundamentally flawed as they are by their inclusive and hierarchical taxonomy, which each time immediately brings the whole game to a standstill and produces an impasse" (74).

The adoption of a categorical approach to personality disorders can be understood in part due to ethical principles within psychiatry. The ‘do no harm principle’ led to Kraepelinian assumptions about mental illness and an emphasis on empirically grounded taxonomic systems that were not biased by unsubstantiated theories about etiology. A taxonomic checklist based on empirical observations rather than bias prone theoretical assumptions developed. It was both categorical and hierarchical, with the diagnosis of a disorder being dependent of the presence of a threshold number categories (usually five) out of a total number (seven to nine) Disorders were organized into three clusters, existing purely to make the disorders easier to remember by associating them with others that have similar symptoms, not based on any theory about their relatedness.

In some cases, particularly with the natural hybrids, it has been viewed as hybrid speciation and the new plants have been viewed as different species from any of their parents. In older taxonomic systems, citrus hybrids have often been given unique hybrid names, marked with a multiplication sign after the word "Citrus", for example the Key lime is Citrus × aurantifolia, and also are referred to by joining the names of the crossed species or hybrids that produced them, as with sunquat – Citrus limon × japonica. Styling a hybrid as such a cross between two species can present challenges. In some cases the parental species that gave rise to a hybrid have yet to be determined, while genotyping reveals some hybrids to descend from three or more ancestral species.
