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.

Contents

The most widely cultivated species is Moringa oleifera , native to the foothills of the Himalayas in northwestern India, [4] a multipurpose tree cultivated throughout the tropics and marketed as a dietary supplement, health food or source for herbalism practices. [5] The fruit pods of Moringa oleifera ("drumsticks") are increasingly consumed as food in many parts of the world, but particularly in South Asia. [6] The leaves are commonly used to make tea. Oils are made from the seeds, while powders can be made from the leaves and roots.

M. stenopetala , an African species, is also widely grown, but to a much lesser extent than M. oleifera.

The genus name is derived from murungai, the Tamil word for drumstick,[ citation needed ] and in India the plant[ which? ] is commonly referred to as the drumstick tree. [7]

Description

Moringa is considered one of the most widely diverse genera for its size ranging from small shrubs ( M. pygmaea ) to large pachycaul trees ( M. ovalifolia ). [8]

Growth habit

Moringa contains a wide range of growth habits that may be subdivided into the following categories:

Leaves

Leaves are typically pinnately compound with entire margins.

Flowers

Flowers may be either bilaterally or radially symmetric. [8] Bottle trees typically produce small, radially symmetric flowers, while other members of the genus produce radially symmetric flowers. Most flowers range in color from white to cream to brown with the notable exception of M. longituba which produces bright red flowers.

Fruit

Fruits are typically elongated, slender, 3-valved "pods" resembling an indehiscent silique (in contrast with a true dehiscent silique). [9] Fruits of M. oleifera (drumstick), are a major agricultural product of India, eaten as a vegetable and used for traditional medicine. [9]

Phytochemistry

Moringa contain a number of sulfurous biochemical compounds called "mustard-oil glycosides" or glucosinolates commonly found in cruciferous vegetables of Brassicaceae. Benzyl glucosinolate along with family-specific glucomoringin and glucosoonjnain have been detected from various Moringa species and are thought to be the cause of the bitter taste in some Moringa leaves. [10] [11]

Taxonomy

Higher-level classification

The monotypic family, Moringaceae, containing genus Moringa has been placed in the order Brassicales according to most modern taxonomic systems, including the APG IV system. [12] Molecular data has suggested a close relationship between Moringaceae and Caricaceae with many identifying a "Caricaceae-Moringaceae" clade within Brassicales. [12] [13] Prior to the availability of molecular data, morphological classification of Moringaceae placed the family in either Brassicales or Sapindales due to the unusual morphological diversity of the family. [14]

Classification within the genus

Moringa contains three widely recognized clades—Donaldsonia, Moringa, and Dysmoringa. [15] Donaldsonia, once thought to be a subgenus of Moringa, is a non-monophyletic clade identifiable by radially symmetric flowers and containing the bottle trees M. drouhardii, M. hildebrandtii, M. ovalifolia, and M. stenopetala. [8] The Moringa clade contains all other members of genus Moringa (except M. longituba) characterized by irregular floral symmetry, perigynous flowers, and short receptacles. [15] The Dysmoringa clade contains the species M. longituba which diverges from common Moringa clade characteristics due to its long receptacle and red flowers. [8] The exact phylogenetic relationship between members of Moringa continues to evolve with growing molecular data, though the Donaldsonia clade is consistently identified as the basalmost clade within the family.

Asterales is an order of dicotyledonous flowering plants that includes the large family Asteraceae known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals.

The Brassicales are an order of flowering plants, belonging to the eurosids II group of dicotyledons under the APG II system.

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.

The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. The 1200 to 1350 species are in about 100 genera. All but seven 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.

The Limnanthaceae are a small family of annual herbs occurring throughout temperate North America. There are eight species and nineteen taxa currently recognized.

<span class="mw-page-title-main">Glucosinolate</span> Class of chemical compounds

Glucosinolates are natural components of many pungent plants such as mustard, cabbage, and horseradish. The pungency of those plants is due to mustard oils produced from glucosinolates when the plant material is chewed, cut, or otherwise damaged. These natural chemicals most likely contribute to plant defence against pests and diseases, and impart a characteristic bitter flavor property to cruciferous vegetables.

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

Gerrardina is a genus of two species of trees, shrubs, and scrambling shrubs found in southeastern Africa. Until recently, the genus was placed in the polyphyletic family Flacourtiaceae, but it was abnormal there due to its apical placentation, small embryos, and mucilaginous foliar epidermis. Analyses of DNA data indicated that the genus did not fit in any known plant family and not clearly in any then-recognized order, and a new family, Gerrardinaceae, was thus created for it. Later analyses of additional DNA data and data from wood anatomy indicated that the family should be placed in the order Huerteales.
