What are Malpighiales?

Malpighiales is a large order of flowering plants with 40 families, more than 700 genera, and almost 16,000 species. Many families are tropical and not well known; however, some well-known members include the willow, violet, passion-flower, mangrove, coca, and spurge families. The leaves of Malpighiales are often toothed and stipulate. Their basic floral construction is common to basal eudicots, with sepals, petals, and often 10 stamens all free, a nectary, and superior ovaries with three to five fused carpels. Also, the seeds usually have little endosperm, and the seed coat has a fibrous layer.

What types of plants are included in the Malpighiales order?

The Malpighiales order is a large group of flowering plants with over 16,000 species across 40 families. Well-known members include Salicaceae (willow), Violaceae (violet), Passifloraceae (passion-flower), Euphorbiaceae (spurge or croton), Rhizophoraceae (mangrove), and Erythroxylaceae (coca) families. These families are organized into nine main groups, with unassigned families, including Malpighiaceae and Elatinaceae ; Ochnaceae , Medusagynaceae , and Quiinaceae ; and Caryocaraceae , Ctenolophonaceae , and Humiriaceae .

Where can Malpighiales plants commonly be found?

Malpighiales is a large order of flowering plants with 40 families, more than 700 genera, and almost 16,000 species. Many families are tropical and not well-known. Some well-known members of the order include the willow family (Salicaceae), violet family (Violaceae), and passion-flower family (Passifloraceae). Malpighiaceae contains 68 genera and 1,250 species of lianas to trees, which are found throughout the tropics, especially in the Neotropics, and into the subtropics. Elatinaceae contains 2 genera and 35 species of herbs to subshrubs, which are native to moist or wet habitats worldwide, although most are tropical or subtropical.

What are some important features of Malpighiales plants?

Malpighiales is a large order of flowering plants with around 40 families, over 700 genera, and almost 16,000 species. While many of the families are not well-known, some familiar ones include Salicaceae (willow), Violaceae (violet), and Euphorbiaceae (spurge). Common characteristics of plants in the Malpighiales order: * Leaves are often toothed and stipulate. * Basic floral construction is common to basal eudicots. * Flowers have sepals, petals, and often 10 stamens all free. * Nectary and superior ovaries with three to five fused carpels. * Seeds usually have at most little endosperm. * The seed coat has a fibrous layer.

Can you name a few well-known families or species in the Malpighiales order?

The Malpighiales order is a large group of flowering plants with over 16,000 species across 40 families. While many of these families are not well-known, some familiar examples include:

Why is the Malpighiales order significant in plant classification and biodiversity studies?

The Malpighiales order is significant in plant classification and biodiversity studies because it is a large order of flowering plants with almost 16,000 species across 40 families and over 700 genera. It demonstrates how molecular techniques have transformed plant phylogeny since the 1990s. The families within Malpighiales were previously placed in various orders. The order has strong molecular support and is morphologically coherent, though not very distinctive. It is part of the Rosids I group of the core eudicots. Well-known members include the willow family and violet family .

Malpighiales, large order of flowering plants that includes 40 families, more than 700 genera, and almost 16,000 species. Many of the families are tropical and poorly known, but well-known members of the order include Salicaceae (willow family), Violaceae (violet family), Passifloraceae (passion-flower family), Euphorbiaceae (spurge or croton family), Rhizophoraceae (mangrove family), and Erythroxylaceae (coca family).

It used to be said of the former order Violales (in the Cronquist botanical system), which is now part of Malpighiales, that hardly any list of characters defined it. The same is clearly true of this more broadly delimited order under the Angiosperm Phylogeny Group II (APG II) botanical classification system (see angiosperm). However, some characters are quite common: the leaves of Malpighiales are often toothed and stipulate, and their basic floral construction is that common to basal eudicots—with sepals, petals, and often 10 stamens all free, a nectary, and superior ovaries with three to five fused carpels. In addition, the seeds have usually at most little endosperm, and the seed coat has a fibrous layer.

Malpighiales is a member of the Rosids I group of the core eudicots, perhaps most closely related to Oxalidales. In the past the families of Malpighiales were placed in a variety of orders, and many other families now placed in other Rosid orders were once thought to be related to these families. Included here are Flacourtiaceae, although the family as such is no longer recognized. It has been broken up into several parts, with most of its genera reassigned to Salicaceae and Achariaceae. Malpighiales as a clade has quite strong molecular support and is morphologically fairly coherent, even if not very distinctive. The families are generally organized into nine main groups, with a large number of unassigned families, as listed here:

Malpighiaceae and Elatinaceae
Salicaceae, Violaceae, Passifloraceae, Achariaceae, Turneraceae, Malesherbiaceae, Lacistemataceae, and Goupiaceae
Erythroxylaceae and Rhizophoraceae
Clusiaceae, Bonnetiaceae, Podostemaceae, and Hypericaceae
Ochnaceae, Medusagynaceae, and Quiinaceae
Chrysobalanaceae, Dichapetalaceae, Trigoniaceae, Balanopaceae, and Euphroniaceae
Putranjivaceae and Lophopyxidaceae
Euphorbiaceae, Peraceae, and Rafflesiaceae
Phyllanthaceae and Picrodendraceae
Unassigned families: Caryocaraceae, Ctenolophonaceae, Humiriaceae, Linaceae, Peridiscaceae, Irvingiaceae, Pandaceae, Ixonanthaceae, and Centroplacaceae.

Malpighiaceae and Elatinaceae

Malpighiaceae contains 68 genera and 1,250 species of lianas to trees, which are found throughout the tropics, although especially in the Neotropics, and into the subtropics. Byrsonima (150 species), Malpighia (130 species), Heteropterys (120 species), Stigmaphyllon (100 species), Banisteriopsis (90 species), Bunchosia (55 species), Mascagnia (50 species), and Malpighia (40 species) are all restricted to the New World. Acridocarpus (30 species), mostly from Africa, is the largest genus in the Old World. Members of Malpighiaceae usually have opposite leaves that lack teeth. The hairs are single-celled and T-shaped, and there are often conspicuous glands on the leaf or petiole. The characteristic flowers have four or five sepals, often with large paired glands on their backs; the petals are strongly narrowed and stalked at the base and are crumpled in bud; and there are three carpels, each with a single ovule. There is no nectary, and pollination is effected by bees, which remove waxes from the sepal glands. The pollinating bees are absent in the Old World, and members of Malpighiaceae there may lack sepal glands or may secrete nectar. The sepals and filaments often persist at the base of the fruit, which is typically dry and with a variable number of wings.

Elatinaceae contains 2 genera and 35 species of herbs to subshrubs, which are native to moist or wet habitats worldwide, although most are tropical or subtropical. Bergia (25 species) and Elatine (10 species) are especially widespread genera. Members of Elatinaceae have opposite, more or less toothed leaves with small paired thin and brownish stipules. They have very small flowers. Elatinaceae species are often important economically as weeds in rice fields and irrigation ditches, where they also play an important ecological role in the prevention of soil erosion.
