Suprageneric Names: Difficult under any Code. James L. E-mail: jreveal umd. Scientific names above the rank of genus suprageneric names as applied to groups of plants covered presently by the International Code of Botanical Nomenclature are variously created and recognized. Such names may or may not have priority, may or may not be based on an included generic name and thus may or may not have a type, are always ranked, and occasionally are even validly published.

Over the past half century the trends have been to recognize monophyletic suprageneric groups whose names are based on an included generic name, and to ascribe ranks in a more or less uniform manner. Over the last fifteen years efforts have been made to ascertain priority at the ranks of family and belowdetermine validity, note current use, and more accurately ascribe authorships and bibliographic references.

With the creation of suprageneric names starting in the s, promoted in the s, and championed by numerous authors in the s, there is a rather uniform set of names applied for all groups of plants. Starting in what are the types of causal loop diagram s names and ranks proliferated and the process continued well into the s. The problems for the proponents of both the International Code meaning of symbionts Botanical Nomenclatureand the proposed PhyloCode regarding suprageneric names are numerous.

While rank is not an issue for followers of the PhyloCodeit is clear that there are subclades within clades so that a hierarchical system of names would be useful. This can be accomplished by adopting a limited number of traditional terminations. Inasmuch as the PhyloCode is a new effort write an example of phylogenetic system of classification bring nomenclatural stability to all organisms, both extant and fossil, this is a singular opportunity to adopt the best of the existing codes of nomenclature and establish a new system of nomenclature for suprageneric names.

Accordingly, I urge adoption of a limited number of terminations and that all suprageneric names should be based on an included generic name. Even though clades, according to the PhyloCodeare defined by their circumscriptions, rather than types, use of a well-known included generic name, coupled with a limited set of terminations, would be a ready means of referring to any clade by non-taxonomists who, after all, are important clients for all of systematics. Suprageneric names are an integral part of the vocabulary used in nearly all aspects of biology and in particular systematics dealing with the identification, classification and naming of extant and fossil organisms.

Suprageneric names are those used to refer to groups of organisms above the rank of genus. Such names have a long, established tradition of use. My remarks will be confined to those organisms covered presently by the International Code of Botanical Nomenclature ICBN and more narrowly the so-called vascular plants. My purpose is to review the history of suprageneric names for this group up to the present time, propose a scheme for recognizing established clades within vascular plants, and to urge adoption in the proposed PhyloCode of the better and now generally established principles for the naming of groups found in ICBN.

History of Suprageneric Names and Classification Schemes. Modern scientific names of plants, by international agreement, begin with the publication of Species plantarum by the Swedish naturalist Carl Linnaeus in Linnaeus basically adopted the concept of genus established a half century earlier by the French botanist Joseph Pitton de Tournefort in a three-volume work, Institutiones rei herbariae published in Suprageneric names had their formal original after in a two volume work published by write an example of phylogenetic system of classification French botanist, Michel Adanson.

His book, Familles des plantespublished in andattempted to organize genera into natural groups. Adanson adopted several of the pre-Linnaean names for families we recognize today, such as ApocynaceaeBoraginaceaeCompositaeCruciferae, GramineaeLeguminosaeMalvaceaePinaceaePortulacaceaeRanunculaceaeSolanaceaeand Umbelliferae to mention just a few. InAntoine published his own book, Genera plantarumwherein he arranged all genera of vascular plants into exactly families.

The Jussieu arrangement of genera was a direct threat to the Linnaean model. Most of the French, German and eastern European authors prior to the s adopted natural families whereas those associated with the English empire and the Scandinavian countries followed Linnaeus. During the 40 year period from until the number of validly published family names grew rapidly, numbering close to Leading the effort to organized vascular plants particularly into viable groups was August Johann Georg Carl Batsch, write an example of phylogenetic system of classification professor of botany at Jena in Germany.

His efforts culminated in his Synopsis universalis analytica generum plantarum and the classic Tabula affinitatum regni vegetabilis published in He grouped his families into classes. The first attempt at a phylogenetic tree for the flowering plants, coupled with a key to them, was published by the Lyon botanist Augustin Augier in By lateseveral orders were established. Constantin Samuel Rafinesque, in his Entity relationship model de la natureproposed numerous ordinal, family and subfamily names, although few were validly published.

Augustin Pyramus de Candolle continued the French domination of natural systems by establishing unranked names for such groups as the ferns, conifers and flowering write an example of phylogenetic system of classification in the first volume write an example of phylogenetic system of classification his Regni vegetabilis systema naturale published in He also subdivided the flowering plants into two groups, conforming to the traditional monocotyledonous angiosperms and the dicotyledonous ones.

Other ordinal names were soon established by the Belgian botanist and politician Berthélemy Charles Joseph Dumortier in his Analyse des familles des plantes published, probably, late in Starting innumerous authors around the world began to adopt the Jussieu model as outlined by Candolle, and over the next decade, numerous publications appears that attempt to summaries all groups of plants mainly at ranks above that of genus. Foremost among these authors was Englishman John Lindley whose technical writings and textbooks, notably An introduction to the natural system of botanyended the Linnaean era within the British Empire.

The proliferation of authors, and natural schemes, would rapidly increase during this decade. Besides Lindley, inthere were other works by Friedrich Gottlieb Bartling Ordines naturales plantarum and Friedrich Rudolphi Systema orbis vetetabiliumboth Germans. Three years later, Lindley reduced the entire subject to a simple key in a 28 page booklet entitled Nixus plantarum. Lindley encouraged others to publish.

One, a fellow professor in London, wrote a detailed textbook on all plants in entitled simply Outlines of botany. He covered his subject in pages of small type. Unfortunately, Burnett died in mid-summer of that year, and like most botanical textbooks, the numerous new names therein were ignored until the early s. Burnett differed from many of his contemporaries, including Lindley, for he subdivided his families into subfamilies rather than tribes or sections the latter an incorrect rank at this level according to ICBN.

That same year, Carl Friedrich Philipp von Martius went to the other extreme, summarizing all plants at numerous ranks in his 72 page pamphlet Conspectus regni vegetabilis. Another major author of this period was Ludwig Reichenbach, professor of natural history at Dresden and director of the botanical garden. A prolific author he proposed numerous names at several ranks most of which were not validly published.

Still, his organization of plants into groups was significant. His textbook Uebersicht des Gewaechs-Reichs was quickly followed or perhaps published simultaneously by Conspectus regni vegetabilis. In came Das Pflanzenreich write an example of phylogenetic system of classification to be followed by his Handbuch des natürlichen Pflazensystems in In each instance, groups were refined as more information became available.

Fellow professor Karl Julius Perleb of the University of Freiburg, like Reichenbach, published a series on books on the classification of plants, the most notable being his Clavis classium of Here many suprageneric names were validly published. The Russian botanist, Paul Fedorowitsch Horaninov published three works filled with suprageneric names. His contribution during this decade was Primae lineae systematis naturaebut his later two books, Tetractys naturae and Characteres essentials familiarum would have a greater impact nomenclaturally.

Foremost of the s were two workers who truly altered, and in many instances, stabilized suprageneric names for the next half century. Published in 18 parts of more than pages, he dealt in detail with the taxonomy of the vascular plants as then understood. This was followed by a summary volume, Enchiridion botanicum published ina year after completing his Genera. Endlicher concentrated on arranging plants into classes, orders, and families.

Writing at essentially the same time, Carl Friedrich Meisner proposed a slightly different arrangement in his Plantarum vascularium genera. This appeared in 14 parts arranged in two more or less simultaneously published segments from until Endlicher provided detailed descriptions of all of his taxa while Meisner concentrated on the diagnostic features by which each group could be recognized; these were often arranged in keys.

Although first published inthe linear arrangement of orders and families was already set mainly by Bentham. In other words, this work did not reflect the new theory of evolution and natural selection proposed by Charles Darwin in By now the family circumscriptions and available names were largely in place even at the rank of tribe. This meant that the two men could concentrate on genera.

What is average speed in simple words a result, authors over the next 20 years relied mainly on Bentham and Hooker for their classification system. The establishment of names above the rank of class was slow to appear. One of the currently used names today for the ferns, Pteridophytawas proposed only inand then by Wilhelm Philipp Schimper in the paleobotanical literature in K.

Zittel, Handbuch der Palaeontologie. Lycopodiophyta would also appear first in the fossil literature, being proposed by the British palaeobotanist Dukinfield Henry Scott in his edition of Studies in fossil botany. Although not realized by most botanists at the time, the majority of names at the rank of class were proposed by Bartling, Endlicher, Horanonow and Meisner in the s and s.

The most prolific author of names at this rank write an example of phylogenetic system of classification the French palaeobiologist Adolphe Théodore Brongniart. His several works on algae, fungi and fossil plants are replete with new suprageneric names. Today, only a few are in current use. Global botany moved from England to Germany during the Engler and Prantl era which, in many respects, was to be in vogue for a century.

Heinrich Gustav Adolf Engler and his brief compatriot, Karl Anton Eugen Prantl, whose early death in would not see an end to his name in print for many decades more, would be the driving force behind an effort to summarize in detail the botanical world from an evolutionary point-of-view. Their major publications, Die natürlichen Pflanzenfamilien and Das Pflazenreichwould dominate plant classification longer than any one before or after.

These authors and their numerous collaborators effectively dominated systematic botany, and to this very day many herbaria still have their collections arranged according to Engler and Prantl. These authors attempted to provide a complete classification at all suprageneric ranks. The consistency to which Engler held to their system of classification meant that from the s until the s there was basically a single systematic view of the plant world above the rank of genus.

What is the logical equivalent of the hang input were challengers, write an example of phylogenetic system of classification none ever reach the dominance in their life time that Engler did in his. Most of the competitive schemes were minor modifications of the Englerian one, and while some authors presented new, critical observations, they were largely ignored.

Laboring during this period was Charles Edwin Bessey, an American botanist who resided in the hinterlands at the University of Nebraska. It would be Bessey who would validate several suprageneric names in his textbooks, starting with the first edition of his Botany for high schools and colleges published in The guiding principles of the Engler and Prantl system would, with time, prove to be faulty so that the sequence of taxa gradually became replaced by the Besseyan sequence, but not until the s.

Hutchinson write an example of phylogenetic system of classification the dicotyledonous flowering plants could be divided into two great groups, one basically herbaceous and the other basically woody. Hutchinson had access to the great garden and herbarium at Kew and devoted much of his professional career to examining specimens and writing detailed descriptions of suprageneric taxa. While he published several new names in journals, his system was outlined in a series of books starting with The families of flowering plants published in two volumes, the first inthe second in A second edition was published in ; his last scheme treating only the dicots appeared in Evolution and phylogeny of flowering plants.

Published in German, this book put Takhtajan among the leaders of a modern system of vascular plant classification although he had published significant works without validating names from onward. InCronquist and Takhtajan began visiting one another, exchanging ideas and concepts, but with each retaining their lumper Cronquist and splitter Takhtajan views of the flowering plants. Jointly, and with Walter Zimmerman of German, the three proposed a series of higher suprageneric names in the journal Taxon Thorne dominated the development of angiosperm classification systems over the next 30 years.

Though these proposals increase the number of genera in the group by resurrecting many names in order to comply with the phylogenetic hypothesis, I think it does a good job to preserve an important level of information. Support for lumping these two taxa into one genus is strong. The alternative NO would be to lump all four groups into Anisognathus H. Comments solicited from Dan Lane :.
