Magnoliopsida

(Class)

Overview

[ Back to top ]

A phylum within the plant kingdom comprising plants with a vascular system that bear flowers during at least some stage of their life cycle. The phylum is further subdivided into dicotyledons and monocotyledons. The Magnoliopsida is the largest phylum of land plants, represented by over 250 000 species world-wide. Syn. Angiospermophyta.

Orders

Adoxales

[more]

Alismatales

Alismatales is an order of flowering plants including about 2500 species. Plants assigned to this order are mostly tropical or aquatic. [more]

Amborellales

[more]

Apiales

The Apiales are an order of flowering plants. The families given at right are those recognized in the APG III system. This is typical of the newer classifications, though there is some slight variation, and in particular the Torriceliaceae may be divided. [more]

Aquifoliales

[more]

Araliales

Cornales is an order of flowering plants, basal among the asterids, containing about 600 species. Plants within Cornales usually have four-parted flowers, drupaceous fruits, and inferior gynoecia topped with disc-shaped nectaries. Under the APG system, Cornales includes the following families: [more]

Aralidiales

[more]

Arecales

Arecaceae or Palmae (also known by the name Palmaceae, which is considered taxonomically invalid, or by the common name palm tree), are a family of flowering plants, the only family in the monocot order Arecales. There are roughly 202 currently known genera with around 2600 species, most of which are restricted to tropical, subtropical, and warm temperate climates. Most palms are distinguished by their large, compound, evergreen leaves arranged at the top of an unbranched stem. However, many palms are exceptions to this statement, and palms in fact exhibit an enormous diversity in physical characteristics. As well as being morphologically diverse, palms also inhabit nearly every type of habitat within their range, from rainforests to deserts. [more]

Asparagales

Asparagales is the name of an order of plants, used in modern classification systems such as the APG III system (which is used throughout this article). The order takes its name from the family Asparagaceae and is placed in the monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985. Before this, many of its families were assigned to the old order Liliales: a very large order containing almost all monocots with colorful tepals and without starch in their endosperm. DNA sequence analysis indicated that Liliales should be divided into at least Liliales, Asparagales and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. [more]

Asterales

Asterales is an of dicotyledonous flowering plants that includes the composite family (Asteraceae) and its related families. [more]

Canellales

Canellales is the botanical name for an order of flowering plants, one of the four orders of the magnoliids. It is defined to contain two families: Canellaceae and Winteraceae, which comprise 136 species of fragrant trees and shrubs. The Canellaceae are found in tropical America and Africa, and the Winteraceae are part of the Antarctic flora (found in diverse parts of the southern hemisphere). Although the order was defined based on phylogenetic studies, a number of possible synapomorphies have been suggested, relating to the pollen tube, the seeds, the thickness of the integument, and other aspects of the morphology. [more]

Capparales

Capparales is a botanical name of an order of flowering plants. It was used in the Cronquist system for an order in subclass Dilleniidae and in the Kubitzki system, nowadays. In the 1981 version of this system it included : [more]

Caryophyllales

Caryophyllales is an order of flowering plants that includes the cacti, carnations, amaranths, ice plants, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. [more]

Celastrales

Celastrales is an order of flowering plants. They are found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. There are about 1200 to 1350 species in about 100 genera. All but 7 of these genera are in the large family Celastraceae. Until recently, the composition of the order and its division into families varied greatly from one author to another. [more]

Ceratophyllales

Ceratophyllum is a cosmopolitan genus of flowering plants, commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. They are usually called hornworts, although this name is also used for unrelated plants of the division Anthocerotophyta. [more]

Chloranthales

Chloranthaceae () is the botanical name of a family of flowering plants. The family consists of four genera, totalling several dozen species, of herbaceous or woody plants occurring in Southeast Asia, the Pacific, Madagascar, Central & South America, and the West Indies. Members of this family are aromatic and have opposite, evergreen leaves with distinctive serrate margins and interpetiolar stipules (similar to the stipules found in family Rubiaceae). The flowers are inconspicuous, and arranged in inflorescences. Petals are absent in this family, and sometimes so are sepals. The flowers can be either hermaphrodite or of separate sexes. The fruit is drupe-like, consisting of one carpel. [more]

Circaeasterales

[more]

Cistales

Violales is a botanical name of an order of flowering plants and takes its name from the included family Violaceae. The name has been used in several systems, although some systems used the name Parietales for similar groupings. In the 1981 version of the influential Cronquist system, order Violales was placed in subclass Dilleniidae with a consisting of the families listed below. The Angiosperm Phylogeny Group system does not recognize order Violales; Violaceae is placed in order Malpighiales and the other families are reassigned to various orders as indicated. [more]

Commelinales

Commelinales is the botanical name of an order of flowering plants. It comprises five families: Commelinaceae, Haemodoraceae, Hanguanaceae, Philydraceae, and Pontederiaceae. All the families combined contain over 800 species in about 70 genera; the majority of species are in the Commelinaceae. Plants in the order share a number of synapomorphies that tie them together, such as a lack of mycorrhizal associations and tapetal raphides. Estimates differ as to when the Comminales evolved, but most suggest an origin and diversification sometime during the mid- to late Cretaceous. Depending on the methods used, studies suggest a range of origin between 123 to 73 million years, with diversification occurring within the group 110 to 66 million years ago. The order's closest relatives are in the Zingiberales, which includes ginger, bananas, cardamom, and others. [more]

Convolvulales

[more]

Cornales

Cornales is an order of flowering plants, basal among the asterids, containing about 600 species. Plants within Cornales usually have four-parted flowers, drupaceous fruits, and inferior gynoecia topped with disc-shaped nectaries.

One of major characteristics of the Cucurbitales is the presence of unisexual flowers, mostly pentacyclic, with thick pointed petals (whenever present) (Matthews and Endress, 2004).
