About This Presentation

The Fabaceae or Leguminosae, commonly known as the legume, pea, or bean family, are a large and economically important family of flowering plants. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit and their compound, stipulate leaves.

Leguminosae Family & Crude Drugs

Fabaceae (Leguminosae) The Pea or Bean Family Scientific Name : Astragalus australis Class : Magnoliopsida (dicot) Sub-Class : Rosidae Order : Fabales Family : Fabaceae Subfamily: 1. Papilionoideae 2. Caesalpinoideae 3 . Mimosoideae

750 genera 19,500 species Found all over the world, concentrated in warm temperate regions in the Northern and Southern Hemisphere (3rd largest family of flowering plants ) Geographical range: North America, Europe, Northwest Asia

Habit: These are herbs, shrubs, trees, twiners or climb-errs. Roots : The roots of many species, particularly of Pap-ilionaceae, have tubercles. Leaves : These are alternate, pirnnately compound, and rarely simple, as in rattlewort (Crotalaria sericea), camel’s foot tree (bauhinid) and some species of desmodium, e.g. D. gangeticum, with a swollen leaf-base known as the pulvinus. There are two, usually free, stipules. Flowers: These are bisexual and complete, regular or zygomorphic or irregular, and hypogynous or slightly perigynous. Calyx : There are usually 5 or (5) sepals, with the odd one anterior (away from the axis). Sometimes there are four sepals. They may be united or free. Corolla: 5 petals (1 standard, 2 wing, 2 keel)

Flower and Corolla:

Androecium: There are usually 10 or more stamens (often less than 10 by reduction) free or united. Gynoecium : There is one carpel. The ovary is one-celled, with one to many ovules. It is superior and the placentation is marginal. The ovary often borne on a long or short stalk is called the stipe or gynophore. Fruit : This is mostly a legume or pod (dehiscent), or sometimes a lomentum (indehiscent). This is the second biggest family among the dicotyledons, and has varying characteristics. As such, it has been divided into the following sub-families : P apilionaceae , Caesalpin-ieae and Mimoseae. The division is primarily based on the characteristics of the corolla and the stamens.

Gynoecium Androecium & Fruit: LOMENT LEGUME

Sub–families The Family is divided into three sub–families: (a) Papilionaceae This sub-family has about 400 genera and 9000 species. The members of this family occur all over the world. particularly \A arm and temperate regions.   Habit : These are trees. shrubs or herbs. Stem : It may be herbaceous. woody or climber with tendrils. Tendrils are wiry. coiled and thread like structure. Leaves : They have compound (rarely simple), alternate and stipulate leaves. The stipules are mostly leafy. Sometimes, these leaves are partially or completely modified into tendrils. Inflorescence : It may be Racemose or solitary axillary. Flowers : They have bisexual. zygomorphic, hracteate, pedicillate, perigynous. pentamerous and papilionaceous. Calyx : ‘They have 5 sepals These petals are mostly united to form tube. These are hairy. Corolla :  They have papilionaceous corolla. 111 this case. there are 5 clawed petals. These petals are not similar.

Economic Importance of Papilionaceae Food:  Most of the important pulses are belonged to this family. These pulses are used as food. Pulses are rich in proteins. The common species of pulses are Grain, Pea, and Kidney bean . 2.Fodders : Medicago sativa (Alfalfa) is one of the best forage crops. Vicia Melilotu and Trifolium are also cultivated as main fodder crops . 3.Timber :  Many plant of this family provide timber for building furniture and fuel. Main timber plants are   Butea, Dalbergia   etc . 4.Vegetable oil:  The seed of  Archis hypogea   (peanut) are edible.  Common Species Lathyrus odoratus: Sweet pea A rachis hypogea: Peanut Cicer arietinum: Chick pea Dalbergia sisso: Shishant

(b) Caesalpiniaceae (Cassia family ) This family has 152 genera and 2300 species. It has 16 genera and 60 species in Pakistan. Ornamental plants: Bauhinia varigata (kuchnar), Cassia Stem: It is erect, woody herbaceous or climbing . Leaves: The leaves are compound (rarely simple), pinnate and Inflorescence: It may he axillary or terminal raceme or it may Flower: Flower is bisexual, zygomorphic ( rarely Calyx: Sepals are 5. They are often coloured and free or connate Androecium: Stamen are 10 or less (rarely numerous). They Gynoecium: They have one simple carpel. Ovary is superior and Habit: Mostly tree or shrubs. Some are woody climbers, rarely Fruit: Its fruit is legume .

2 . Vegetables and fruits: T he   leaves and flower bud of  Bauhinia variegate   are used as vegetable. The acidic fruit of  Tamarintlus indica  (JIM) are edible. It is rich in tartaric acid . 3. Tanning and dyes:  The bark of  Buahinia   and  Tamarindus indica   is used in tanning. Common species Tamarindus indica Cassia fistula. Amaltas Baultinia varigata Kachnar Cas ia senna 1.Medical importance The leaves of cassia alata are used to cure ring worm and skin diseases. The leaves of Cassia senna and Cassia obovata giN c a drug called Senna. Senna forms a Cytmetera. This oil is applied externally for skin diseases

( c) Alimosaceae ( Acacia family ) This family 56 .  genera and about 2800 species. There are 11 genera and in Pakistan Familiar Plants   Habit : Mosly trees or shrubs. Rarely climbers or herbs. Most of them are xecophytes. Stem : Mostly woody Leaves : They have pinnate, compound, alternate and stipulate leaves. The stipules are modified into thrones. Inflorescence : It is spike like or head or umbel. It is rarely racemose or globose umbel. Flowers : The flower is bisexual, actinomorphic, hypogynous to slightly perigynous and bracteate . Economic Importance   Wood:   Many trees of this family provide commercially important wood, for example,  Acacia, Albizzia and Xylia.  Their wood is used for construction, for furniture or for fuel. Gum:   Gum is obtained from  Acacia nilotica  and  Acacia senegal. Dye:   A dye  Katha  is obtained from  Acacia catechu. Medicinal plants:   The tender leaves of  Acacia nilotica  are used as blood purifier.
