  • It ispopular known as matar kul ,about 490 genera & 12000 spices are found in it.100 genera and 748 species of this sub family are found in India. This family is cosmopolitan most of the plants &mesophyte. Some plants become xerophytes' due to modification of leaves such as- aluminum pseudoalahgi halophtes. •Vegetative character:- • (i) Habit (ii) Root (iii) Stem (iv) Leaves • (i) Habit :- annual or biennial herbs as- melilotus climber such as-pisum Vicia Delicious (sem)Shrub,woody climber jaise- Dalbergiya etc. 3.Distribution

  2.ROOT:- • Branches taproot . Special types of tubercle are found on them in which a bacteria called rhizobium leaves symbiotically. These provide a safe place for the bacteria to live N2 of the atmosphere into it’s compound which increases the fertility of the soil.

  • The stemis usually branched erect or weak ascending. It is vegetarian or may be woody it is cylindrical soild and sometimes hollow it is divided into nodes and interludes it is branched. • Leave:- cauline and branched alternate stipulate Lateral like iridium converted into leaf like pea pisum lathers etc alkali. Stem:-

  (i) Infloroscence:- thesecharacters are floral character racemose spike like- Urania capitulum like- trifolium solitary axillary ordelineated flower compound Inflorescences sequences are also found. •(ii)Flower :- flower intermediate is medically zygomorphic rediellate bracteate mostly two bracteoles like sesbania bisexuality complete Pentamerous hypogynous or slightly foliaceous and persistent Floral character:-

  • Five sepalsgamosepalous subject sepals anterior sepals ascending imbricate or valdate medicago the sepals are free. • (iv) Corolla :- petals are five separate polypetalous the group is known as papilionaceous the posterior petals is the largest on the outer side it is called strand vegxillum. • There are two sides in the lateral part called wings two anterior petals are small and fused. 3.Calyx:-
• 11.
  • Stamen areten (9)+1 diadelphous.the posterior Stamen is free and the remaining nine from a union which forms a covering around the carple. There is a cover over the puntanute which burstat from the front some plants have only nine stamens and they from a compound posterior stamen is absent like in peanuts arches' hypogea dalbergia sisso etc. Androecium:-
• 12.
  GYNOCIUM:- • Monocarpellry unilocularsuperior ovary any placentation is marginal sometimes held up by a short or long jab the stigma and are bent several times. • FRUIT:- Legume is the characteristics fruit of this family pod’s is found in some plants. Lome tum is found in desmodium etc the fruits of dalbergia contain Endosome seeds are non endospermic.

  • Dispersal offruits and seeds occurs in various ways such as due to the presence of troublesome pods. In medicago by animal in abruse pricatorius byexplosive machanism in trifolium by winds due to persistent calyx and in trifolium ulex seeds by presence of lelang claisome. SEEDS:-

  • The processof cross-pollination is done by insects. Flower are protandary the flage holds necter the wings provide a plate form for insect pollination. • Floral formula:- %, Bisexual K(5) C1+2+(2) A(9)+1 G_1 Pollination:-
