what is it about
Ligumious flower?
Do you mean leguminous? That just means the quality of being a legume, or a legume-bearing plant. Legumes are dry fruits that usually open on a seam, and include peanuts, peas, and soy beans.
Reply:Check your spelling. Do you mean LEGUMINOUS? Legumes are the plants that give us peas and beans.
Reply:Legumes are plants of the pea or bean family, the Leguminosae (Fabaceae in the USA).
The family is usually divided into three sub-families: Papilionoideae, Caesalpinioideae and Mimosoideae. These sub-families are sometimes recognised as three separate families: Papilionaceae, Caesalpiniaceae and Mimosaceae. The three subfamilies are generally identifiable by their flowers.
1) Papilionoideae -The Papilionoideae is the largest of the three subfamilies with about two-thirds of all the genera and species of the family. It is also the most widespread, extending further into temperate regions than the other two subfamilies.
The majority of the species are herbaceous, although there are some trees and shrubs, e.g. Laburnum and Gorse (Ulex).
For the most part the Papilionoideae are easily recognised by their characteristic papilionaceous (butterfly-like) flowers. The flower is irregular (zygomorphic) and is made up of five petals; a ?banner? petal, two wing petals, and two petals partially fused together to form a boat-shaped keel. The keel encloses the stamens, which are not visible externally.
The Papilionoideae contains most of the important leguminous crop species such as the Soya Bean (Glycine max), Common Pea (Pisum sativum), Chickpea (Cicer arietinum), French Bean (Phaseolus vulgaris), Lentil (Lens culinaris) and Peanut (Arachis hypogaea).
2)Caesalpinioideae - The majority of the Caesalpinioideae are tropical or subtropical trees and shrubs.
The flowers of the Caesalpinioideae are irregular (zygomorphic) with five petals which are not differentiated into standard, wings and keel. The stamens are visible externally.
Several species in this subfamily are well-known tropical ornamentals such as Flamboyant (Delonix regia) and Barbados Pride (Caesalpinia pulcherrima). Alexandrian Senna (Senna alexandrina) is a commercially grown medicinal plant, known for its purgative qualities.
3)Mimosoideae - Like the Caesalpinioideae, the majority of the Mimosoideae are tropical or subtropical trees and shrubs.
The Mimosoideae are characterised by their small, regular (actinomorphic) flowers crowded together, generally into spikes or heads which resemble a pom-pom. The stamens have become the most attractive part of the flower, the five petals inconspicuous. The leaves are predominately bipinnate.
Examples of genera within this subfamily are Acacia and Mimosa. Certain Acacia species are extremely important economically. An extract from the bark of the Golden Wattle (Acacia pycnantha) is used in tanning, several species, such as Australian Blackwood (e.g. Acacia melanoxylon) provide useful timbers and some (e.g. Acacia senegal) yield commercial gum arabic, which is used in a wide range of industrial processes.Shoes
