Examples of "dicotyledoneae"
Within the dicotyledons ("classis prima "
"") the systems recognize this as subclass 1. Thalamiflorae. The full "Ordo", "Tribe" and genera are shown below
The Engler system, in its update of 1964, assigned it to the order Magnoliales, which was placed in subclass Archychlamydeae in class
and in subdivision Angiospermae
The Engler system, in its update of 1964, placed the order in subclassis Archychlamydeae in class
(=dicotyledons) and used this circumscription:

The Engler system, in its update of 1964, also recognized this order and placed it in subclass Archichlamydeae of class

Calyciflorae is a grouping of plants that is no longer used by botanists. Augustin Pyramus de Candolle defined it as a subclass within the class
. It overlapped largely with the modern Rosids group. The group Calyciflorae was defined as:
There are at least 2109 species of dicotyledons found in Montana according to the Montana Field Guide. This is a list of
orders found in Montana. The Montana Natural Heritage Program has identified a number of dicot species as "Species of Concern". Some of these species are exotics (not native to Montana).
Dark septate endophytes have been observed across the plant kingdom in
and Monocotyledonae (Angiospermae), and Equisetopsida, Lycopsida, Polypodiopsida, and Psilotopsida (Gymnospermae). Their diversity of hosts suggests little or no host-specificity in this group. They are found on plants that are non-mycorrhizal as well as plants with known arbuscular, ericoid, orchid, and ectomycorrhizal associations.
Traditionally the dicots have been called the Dicotyledones (or
), at any rank. If treated as a class, as in the Cronquist system, they could be called the Magnoliopsida after the type genus "Magnolia". In some schemes, the eudicots were treated as a separate class, the Rosopsida (type genus "Rosa"), or as several separate classes. The remaining dicots (palaeodicots or basal angiosperms) may be kept in a single paraphyletic class, called Magnoliopsida, or further divided. Some botanists prefer to retain the dicotyledons as a valid class, arguing its practicality and that it makes evolutionary sense.
Prior to the phylogenic classifications of August Eichler and his successors this group corresponds to the Gamopetalae of Bentham and Hooker In Eichler's "Bluthendiagramme", Sympetalae, also classified as Metachlamydeae, was listed as a subclass of the class Dicotyleae, in contrast to the Choripetalae. Adolf Engler and Karl Prantl also listed Sympetalae as a division of the class
in their system, "Die Naturlichen Pflanzenfamilien", with Sympetalae being composed of gamopetalous families Alfred Rendle similarly Sympetalae originated from dicots, and then divided Sympetalae into Pentacyclicae and Tetracyclicae in accordance with the number of flower parts in each group.
which in the Cronquist system are called Magnoliopsida (at the rank of class, formed from the family name Magnoliaceae) and Liliopsida (at the rank of class, formed from the family name Liliaceae). Other descriptive names allowed by Article 16 of the ICBN include Dicotyledones or
, and Monocotyledones or Monocotyledoneae, which have a long history of use. In English a member of either group may be called a dicotyledon (plural dicotyledons) and monocotyledon (plural monocotyledons), or abbreviated, as dicot (plural dicots) and monocot (plural monocots). These names derive from the observation that the dicots most often have two cotyledons, or embryonic leaves, within each seed. The monocots usually have only one, but the rule is not absolute either way. From a broad diagnostic point of view, the number of cotyledons is neither a particularly handy nor a reliable character.
The APG II system (2003; unchanged from the APG system of 1998) allows the option of including it in the family Proteaceae, or treating it as distinct as a segregate family. In as far as APG II accepts the family, it is placed in the order Proteales, in the clade eudicots. This represents a slight change from the APG system of 1998, which did accept this family. The Cronquist system of 1981 recognized the family and placed it in order Hamamelidales, in subclass Hamamelidae in class Magnoliopsida (dicotyledons). The Dahlgren system and Thorne system (1992) also recognized this family and placed it in the order Hamamelidales in superorder Rosanae in subclass Magnoliidae "sensu" Dahlgren and Thorne (dicotyledons). The Engler system, in its 1964 update, also recognized the family and placed it in the order Rosales in subclass Archichlamydeae of class
. The Wettstein system, last revised in 1935, also recognized the family and placed it in the order Hamamelidales in the Monochlamydeae in subclass Choripetalae of the class Dicotyledones. Based on molecular and morphological data the APW (Angiosperm Phylogeny Website) places the family in the order Proteales as a sister family to the Proteaceae, making them the Northern Hemisphere version of this family (cf. AP-website).
