13-566: See text Verbeekinidae are a family of large fusulinaceans characterized by subspherical, planispirally coiled tests and a long coiling axis. The wall is composed of a dense outer tectum and inner alveolar keriotheca. They are most prominent in Japan and Southeast Asia. As presently defined by ( Loeblich & Tappan , 1988) the Verbeekinidae includes three subfamilies: Verbinkininae, Missellinindae, and Pseudodoliolininae. The family
26-457: 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 the seventy-six groups of plants he recognised in his tables families ( familiae ). The concept of rank at that time
39-446: 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 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
52-574: Is entirely Permian , with a range from the Wolfcampian (L Perm.) to the Ochoan (U Perm.) In 1964 Loeblich and Tappan included the Verbeekininae (=Verbeekinidae, sensu 1988) and Neoschwagerininae (= Neoschwagerinidae sensu 1988) in the Verbeekinidae. Treatise . They defined the Verbeekinidae as having a medium-sized, distinctly fusiform ellipsoid morphology with close-spaced foramina along
65-491: 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',
78-526: 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 )
91-518: The base of the septa. A spirotheca (outer wall) composed of tectum and keriotheca was found in early examples of Veebeekinidae, but in later genera may have consisted of a single homogeneous layer. The Verbeekinidae can be equated with the Neoschagerinidae of Cushman. The Verbeekinidae and Neoschwagerinidae are currently distinguished from earlier fusulinaceans, e.g. Fusuninidae and Schwagerinidae , by straight, unfluted or uncorrugated septa,
104-514: 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 ,
117-540: 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
130-550: The presence of "I-beam" like transverse, and an axial septula that hang from the spermatheca, partially subdividing the chambers. The septula reinforced the fluted septa rather than corrugated it. Family (biology) Family ( Latin : familia , pl. : familiae ) 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
143-491: 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 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

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 the use of this term solely within
169-666: 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
