Cronquist System
The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida ( dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida and 19 orders and 65 families in class Liliopsida.

List Of Systems Of Plant Taxonomy
This list of systems of plant taxonomy presents "taxonomic systems" used in plant classification. A wiktionary:taxonomic system, taxonomic system is a coherent whole of alpha taxonomy, taxonomic judgments on circumscription (taxonomy), 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. A system must be alpha taxonomy, taxonomic, that is deal with many plants, by their botanical names. Secondly it must be a system, i.e. deal with the relationships of plants. Although thinking about relationships of plants had started much earlier (see history of plant systematics), such systems really only came into being in the 19th century, as a result of an ever-increasing influx from all over the world of newly discovered plant species. The 18th century saw some early systems, which are perhaps precursors rather than full taxonomic systems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eriocaulales
The Poales are a large order of flowering plants in the monocotyledons, and includes families of plants such as the grasses, bromeliads, and sedges. Sixteen plant families are currently recognized by botanists to be part of Poales. Description The flowers are typically small, enclosed by bracts, and arranged in inflorescences (except in three species of the genus '' Mayaca'', which possess very reduced, one-flowered inflorescences). The flowers of many species are wind pollinated; the seeds usually contain starch. Taxonomy The APG III system (2009) accepts the order within a monocot clade called commelinids, and accepts the following 16 families: The earlier APG system (1998) adopted the same placement of the order, although it used the spelling "commelinoids". It did not include the Bromeliaceae and Mayaceae, but had the additional families Prioniaceae (now included in Thurniaceae), Sparganiaceae (now in Typhaceae), and Hydatellaceae (now transferred out of the monocots; ...

Liliales
Liliales is an order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web system, within the lilioid monocots. This order of necessity includes the family Liliaceae. The APG III system (2009) places this order in the monocot clade. In APG III, the family Luzuriagaceae is combined with the family Alstroemeriaceae and the family Petermanniaceae is recognized. Both the order Lililiales and the family Liliaceae have had a widely disputed history, with the circumscription varying greatly from one taxonomist to another. Previous members of this order, which at one stage included most monocots with conspicuous tepals and lacking starch in the endosperm are now distributed over three orders, Liliales, Dioscoreales and Asparagales, using predominantly molecular phylogenetics. The newly delimited Liliales is monophyletic, with ten families. Well known plants from the order include '' Lilium'' (lily), tulip, the North American wildflower ...

Liliidae
Liliidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used (there are many such systems); the only requirement being that it includes the family Liliaceae. Liliidae in Takhtajan system The Takhtajan system treats this as one of six subclasses within class Liliopsida (= monocotyledons). This subclass consists of: * subclass Liliidae *: superorder Lilianae *:: order Melanthiales *:: order Colchicales *:: order Trilliales *:: order Liliales *:: order Alstroemeriales *:: order Iridales *:: order Tecophilaeales *:: order Burmanniales *:: order Hypoxidales *:: order Orchidales *:: order Amaryllidales *:: order Asparagales *:: order Xanthorrhoeales *:: order Hanguanales *: superorder Dioscoreanae *:: order Stemonales *:: order Smilacales *:: order Dioscoreales *:: order Taccales Liliidae in Cronquist system The Cronquist system treats this as one of five subclasses within class Liliopsida (= monocot ...

Arales
''Arales'' is an order of flowering plants. The name was used in the Cronquist system for an order placed in subclass ''Arecidae'', circumscribed as (1981): * order ''Arales'' *: family '' Acoraceae'' *: family ''Araceae'' *: family ''Lemnaceae'' In the classification system of Dahlgren the Arales were in the superorder Ariflorae (also called Aranae), but did not include Acoraceae as a separate family. Instead, ''Acorus'', its only genus, was included in the Araceae. Arales was the only order included in the Ariflorae. The APG II system elevates the first of these three families to become an order ''Acorales'' of its own (consisting of the single genus, ''Acorus'') and unites the last two of these families into the one family ''Araceae'' assigning this to the order ''Alismatales The Alismatales (alismatids) are an order of flowering plants including about 4,500 species. Plants assigned to this order are mostly tropical or aquatic. Some grow in fresh water, some in mari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandanales
Pandanales, the pandans or screw-pines, is an order of flowering plants placed in the monocot clade in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web systems. Within the monocots Pandanales are grouped in the lilioid monocots where they are in a sister group relationship with the Dioscoreales. Historically the order has consisted of a number of different families in different systems but modern classification of the order is based primarily on molecular phylogenetics despite diverse morphology which previously placed many of the families in other groupings based on apparent similarity. Members of the order have a subtropical distribution and includes trees, shrubs, and vines as well as herbaceous plants. The order consists of 5 families, 36 genera and about 1,610 species. Description Pandanales are highly diverse including large arboraceous plants of tropical rainforests and coastal areas, climbing vines and lianas, as well as very small achlorophyllou ...

Cyclanthales
Cyclanthaceae is a family of flowering plants. Taxonomy Earlier systems, such as the Cronquist system and the Takhtajan system, placed it as the sole family in the order Cyclanthales. In the classification system of Dahlgren the Cyclanthaceae were the sole family of the order Cyclanthales in the superorder Cyclanthiflorae (also called Cyclanthanae). The APG system (1998) and the APG II system (2003) assign it to the order Pandanales in the clade monocots. The family occurs in the neotropics and consists of 12 genera with a total of ca 230 known species (Christenhusz & Byng 2016 ). Subdivision Genera *'' Asplundia'' Harling *''Carludovica'' Ruiz & Pav. *''Chorigyne'' R.Erikss. *''Cyclanthus'' Poit. *''Dianthoveus'' Hammel & Wilder *''Dicranopygium'' Harling *''Evodianthus'' Oerst. *''Ludovia'' Brongn. *'' Schultesiophytum'' Harling *'' Sphaeradenia'' Harling *''Stelestylis'' Drude *'' Thoracocarpus'' Harling Cultivation and uses The family is probably best known for ''Carludovi ...

Arecales
Arecales is an order of flowering plants. The order has been widely recognised only for the past few decades; until then, the accepted name for the order including these plants was Principes. Taxonomy The APG IV system of 2016 places Dasypogonaceae in this order, after studies showing Dasypogonaceae as sister to Arecaceae. However, this decision has been called into question. Historical taxonomical systems The Cronquist system of 1981 assigned the order to the subclass Arecidae in the class Liliopsida (= monocotyledons). The Thorne system (1992) and the Dahlgren system assigned the order to the superorder Areciflorae, also called Arecanae in the subclass Liliidae (= monocotyledons), with the single family Arecaceae. The APG II system of 2003 recognised the order and placed it in the clade commelinids in the monocots and uses this circumscription: * order Arecales *: family Arecaceae, alternative name Palmae This was unchanged from the APG system The APG system (Angi ...

Arecidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used (there are many such systems); the only requirement being that it includes the family Arecaceae.

Zingiberales
The Zingiberales are flowering plants forming one of four orders in the commelinids clade of monocots, together with its sister order, Commelinales. The order includes 68 genera and 2,600 species. Zingiberales are a unique though morphologically diverse order that has been widely recognised as such over a long period of time. They are usually large herbaceous plants with rhizomatous root systems and lacking an aerial stem except when flowering. Flowers are usually large and showy, and the stamens are often modified (staminodes) to also form colourful petal-like structures that attract pollinators. Zingiberales contain eight families that are informally considered as two groups, differing in the number of fertile stamens. A " banana group" of four families appeared first and were named on the basis of large banana-like leaves. Later, a more genetically coherent (monophyletic) "ginger group" appeared, consisting of the remaining four families. The order, which has a fossil re ...

Bromeliales
Bromeliales is an order of flowering plants. Such an order has been recognized by a few systems of plant taxonomy, with a various placement. It appears that it always has had the same circumscription: consisting only of the family Bromeliaceae, the bromeliad or pineapple family. The order is not recognized in the APG II system, of 2003, which places the plants involved in the order Poales. Some examples are: * The Cronquist system of 1981 placed this order in subclass Zingiberidae, of class Liliopsida monocotyledons * The Thorne system (1992) placed the order in superorder Commelinanae in subclass Liliidae monocotyledons * The Dahlgren system placed the order in superorder Bromeliiflorae (also known as Bromelianae) in subclass Liliidae monocotyledonstogether with five other orders. * The Engler system, in its update of 1964, placed the order in class Monocotyledoneae Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and gras ...
