12-429: Dasypogonaceae is a family of flowering plants based on the type genus Dasypogon , one that has traditionally not been commonly recognized by taxonomists; the plants it contains were usually included in the family Xanthorrhoeaceae . If valid, Dasypogonaceae includes four genera with 16 species. The family is endemic to Australia. The best known representative is Kingia australis . The 2016 APG IV system places
24-554: A lack of widespread consensus within the scientific community for extended periods. The continual publication of new data and diverse opinions plays a crucial role in facilitating adjustments and ultimately reaching a consensus over time. The naming of families is codified by various international bodies using the following suffixes: The taxonomic term familia was first used by French botanist Pierre Magnol in his Prodromus historiae generalis plantarum, in quo familiae plantarum per tabulas disponuntur (1689) where he called
36-499: Is commonly referred to as the "walnut family". The delineation of what constitutes a family— or whether a described family should be acknowledged— is established and decided upon by active taxonomists . There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to
48-480: Is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy . It is classified between order and genus . A family may be divided into subfamilies , which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae , but that family
60-483: The Genera Plantarum of George Bentham and Joseph Dalton Hooker this word ordo was used for what now is given the rank of family. Families serve as valuable units for evolutionary, paleontological, and genetic studies due to their relatively greater stability compared to lower taxonomic levels like genera and species. Ordo naturalis In botany, the phrase ordo naturalis , 'natural order',
72-513: The Prodromus of de Candolle and the Genera Plantarum of Bentham & Hooker, the word ordo did indicate taxa that are now given the rank of family. Contemporary French works used the word famille for these same taxa. In the first international Rules of botanical nomenclature of 1906 the word family ( familia ) was assigned to this rank, while the term order ( ordo )
84-433: The clade commelinids , but leaving it unplaced as to order. The commelinids are monocots , the broad group to which, in any event, these plants clearly belong. Studies have confirmed the monophyletic character of the grouping. The following is a phylogenetic tree of the family. Calectasia Dasypogon Baxteria Kingia Family (biology) Family ( Latin : familia , pl. : familiae )
96-530: The family as a rank intermediate between order and genus was introduced by Pierre André Latreille in his Précis des caractères génériques des insectes, disposés dans un ordre naturel (1796). He used families (some of them were not named) in some but not in all his orders of "insects" (which then included all arthropods ). In nineteenth-century works such as the Prodromus of Augustin Pyramus de Candolle and
108-478: The family in the order Arecales , after several studies revealed the family as a sister taxon to Arecaceae , the palm family. Other authors find that the placement of Dasypogonaceae remains undetermined, due to conflicting models, and leave it in an order of its own, the Dasypogonales . The earlier APG III (2009), APG II (2003), and the 1998 APG system all accepted the validity of the family, assigning it to
120-567: The seventy-six groups of plants he recognised in his tables families ( familiae ). The concept of rank at that time was not yet settled, and in the preface to the Prodromus Magnol spoke of uniting his families into larger genera , which is far from how the term is used today. In his work Philosophia Botanica published in 1751, Carl Linnaeus employed the term familia to categorize significant plant groups such as trees , herbs , ferns , palms , and so on. Notably, he restricted
132-541: The use of this term solely within the book's morphological section, where he delved into discussions regarding the vegetative and generative aspects of plants. Subsequently, in French botanical publications, from Michel Adanson 's Familles naturelles des plantes (1763) and until the end of the 19th century, the word famille was used as a French equivalent of the Latin ordo (or ordo naturalis ). In zoology ,

#1732851632822144-651: Was once used for what today is a family . Its origins lie with Carl Linnaeus who used the phrase when he referred to natural groups of plants in his lesser-known work, particularly Philosophia Botanica . In his more famous works the Systema Naturae and the Species Plantarum , plants were arranged according to his artificial "Sexual system", and Linnaeus used the word ordo for an artificial unit. In those works, only genera and species (sometimes varieties) were "real" taxa . In nineteenth-century works such as
