Legumes let in plant like alfalfa , pea plant , trefoil and beans as well as ornamental tree like honey locust , purple poinciana and mimosa . One of the declamatory industrial plant family , leguminous plant are surpassed in number of worldwide species only by the orchid and daisy families . Legumes swear out as foodstuff for valet de chambre and animals as well as help meliorate soil nutrition by fixating nitrogen into low - fertility croplands .

Common Features

Legumes share only one common lineament : from a single flower ovary they develop a fruit ( pod ) that separate open along two seams to unfreeze multiple seeds . Some legumes ' cod do not split clear but do have the two seams . Many may say that all legume fixate atomic number 7 in soils , and while a valid characteristic , not all species of legumes conduct this soil - amend process . Within all the plants in this large family , great variation in leaf anatomical structure , industrial plant physique , blossom shape and birth exist , and taxonomists reach to further group legumes into small groups like subfamilies and genera ( plural of genus ) . subfamily and genus place industrial plant with tightlipped physical characteristics together to show shared bloodline and telling .

Types

leguminous plant include plants that are trees , shrub and herbaceous plant ( perennial or annual plants ) as well as any variety of climbing , rambling or twining vine - like physique . Overall , these types or plant physique have little to do with separate leguminous plant until the genus or mintage stratum . Some legume are toxic , some grow in dry soils , while others are comestible and making love wet – there is huge multifariousness among the Earth ’s legumes .

Legume Family

Known today as Fabaceae and formerly as Leguminosae , the legume fellowship is also called the bean plant or pea house . Some 18,000 species of plants compose this family in any of the nigh 670 different genera . appendage of the family are find grow on all continents except Antarctica , with particularly great diverseness of legume found in the tropic rainforest . Legumes spring up in many other habitats , too .

Subfamily Distinctions

The largest differentiation within the legume family centers on the works ’s blossom structure . These three subfamily are Caesalpinioideae , Mimosoideae and Papilionoideae . Flowers in the Caesalpinioideae have one or many axes of symmetry and typically have one petal that is modified to look like a lip or standard . Examples admit the orchidaceous plant tree ( Bauhinia spp . ) , shower tree ( Cassia spp . ) and the royal poinciana ( Delonix regia ) . Those in Mimosoideae have pompon - like or spidery flowers with many stamens as exemplified by wattles ( Acacia spp . ) or silk tree diagram ( Albizia julibrissin ) . in conclusion , flower of plant in the Papilionoideae have a " butterfly stroke - same " shape or the traditional shape of a pea plant blossom . Their flowers are extremely limited with five petals : one is an good standard or banner , two variety lateral " ear - like " wings and the bottom two fuse together to create a keel . The classical deterrent example is the bloom of any pea or bean as well as wisteria or coral - pea vine ( Kennedia spp . ) .

Modified Classification

Some systematist remove the legume kinfolk altogether and bring up the subfamilies each into family position ( for instance the Cronquist System ) . Thus , any flora formerly simply listed a member of Fabaceae is then placed into the unexampled family based on flower morphology . Caesalpinaceae ( caesalpinia family ) then include four tribes named Caesalpinieae , Cassieae , Cercideae and Detarieae . Mimosaceae ( mimosa family ) is further infract down into four tribe : Acacieae , Ingeae , Mimoseae , and Mimozygantheae . Papilionaceae ( pea family ) include numerous tribes , such as Lotiae , Trifoliae , Galegeae , Genisteae , Hedysareae and Phaseoleae .
