Families

The Brassicales (or Cruciales) are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system. [2] One character common to many members of the order is the production of glucosinolate (mustard oil) compounds. Most systems of classification have included this order, although sometimes under the name Capparales (the name chosen depending on which is thought to have priority). [3]

The order typically contains the following families: [4]

On 20 April 2020, a newly described monotypic species from Namibia, namely, Tiganophyton karasenseSwanepoel, F.Forest & A.E. van Wyk is placed under this order as a monotypic member of new family Tiganophytaceae, which is closely related to Bataceae, Salvadoraceae and Koeberliniaceae. [6]

Historic classifications

Under the Cronquist system, the Brassicales were called the Capparales, and included among the "Dilleniidae". The only families included were the Brassicaceae and Capparaceae (treated as separate families), the Tovariaceae, Resedaceae, and Moringaceae. Other taxa now included here were placed in various other orders.

The families Capparaceae and Brassicaceae are closely related. One group, consisting of Cleome and related genera, was traditionally included in the Capparaceae but doing so results in a paraphyletic Capparaceae. [3] Therefore, this group is generally now either included in the Brassicaceae or as its own family, Cleomaceae. [4] [7]

Setchellanthaceae is sometimes known as the azulita family. [8]

Brassicaceae or Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple, lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall.

<i>Moringa</i> (genus) Genus of flowering plants

Moringa is the sole genus in the plant family Moringaceae. It contains 13 species, which occur in tropical and subtropical regions of Africa and Asia and that range in size from tiny herbs to massive trees. Moringa species grow quickly in many types of environments.

The Limnanthaceae are a small family of annual herbs occurring throughout temperate North America. There are eight species and nineteen taxa currently recognized. Members of this family are prominent in vernal pool communities of California. Some taxa have been domesticated for use as an oil seed crop. Some members are listed as threatened or endangered and have been the focus of disputes over development plans

The APG system of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy. Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016.

The Kubitzki system is a system of plant taxonomy devised by Klaus Kubitzki, and is the product of an ongoing survey of vascular plants, entitled The Families and Genera of Vascular Plants, and extending to 15 volumes in 2018. The survey, in the form of an encyclopedia, is important as a comprehensive, multivolume treatment of the vascular plants, with keys to and descriptions of all families and genera, mostly by specialists in those groups. The Kubitzki system served as the basis for classification in Mabberley's Plant-Book, a dictionary of the vascular plants. Mabberley states, in his Introduction on page xi of the 2008 edition, that the Kubitzki system "has remained the standard to which other literature is compared".

<span class="mw-page-title-main">Capparaceae</span> Family of caper flowering plants

The Capparaceae, commonly known as the caper family, are a family of plants in the order Brassicales. As currently circumscribed, the family contains 33 genera and about 700 species. The largest genera are Capparis, Maerua, Boscia and Cadaba.

<span class="mw-page-title-main">Caricaceae</span> Family of flowering plants

The Caricaceae are a family of flowering plants in the order Brassicales, found primarily in tropical regions of Central and South America and Africa. They are usually short-lived evergreen pachycaul shrubs or small to medium-sized trees growing to 5–10 m tall. One species, Vasconcellea horovitziana is a liana and the three species of the genus Jarilla are herbs. Some species, such as the papaya, bear edible fruit and produce papain.

<i>Cleome</i> Genus of flowering plants

Cleome is a genus of flowering plants in the family Cleomaceae, commonly known as spider flowers, spider plants, spider weeds, or bee plants. Previously, it had been placed in the family Capparaceae, until DNA studies found the Cleomaceae genera to be more closely related to the Brassicaceae than the Capparaceae. Cleome and clammyweed can sometimes be confused. The simplest way to differentiate the two is to compare the seedpods which project out or down on cleome and up on clammyweed.

<span class="mw-page-title-main">Cleomaceae</span> Family of flowering plants

The Cleomaceae are a small family of flowering plants in the order Brassicales, comprising about 300 species in 10 genera, or about 150 species in 17 genera. These genera were previously included in the family Capparaceae, but were raised to a distinct family when DNA evidence suggested the genera included in it are more closely related to the Brassicaceae than they are to the Capparaceae. The APG II system allows for Cleomaceae to be included in Brassicaceae. Cleomaceae includes C3, C3–C4, and C4 photosynthesis species.

<i>Emblingia</i> Genus of flowering plants

Emblingia is a monospecific plant genus containing the species Emblingia calceoliflora, a herbaceous prostrate subshrub endemic to Western Australia. It has no close relatives, and is now generally placed alone in family Emblingiaceae.

<span class="mw-page-title-main">Salvadoraceae</span> Family of flowering plants

Salvadoraceae is a family in the plant order Brassicales, consisting of three genera with a total of 11 known species. They occur in Africa, Southeast Asia, and on Java, suggesting they are probably found in much of Malesia. They are often found in hot, dry areas.

The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system.

<span class="mw-page-title-main">APG IV system</span> 2016 revision of a flowering plant classification

The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one.
