Floral Formula of Fabaceae

Plant taxonomists believe that there are 2 to 3 million plant species on our planet. Angiosperms (flowering plants) account for about two lakh species, with gymnosperms, bryophytes, hydrophytes, and other vascular and nonvascular plants rounding out the list. Depending on their properties, these plants are classified into distinct families. 

Floral Formula of Fabaceae Solanaceae Liliaceae

The floral formula of fabaceae solanaceae liliaceae are as follow: 

The Fabaceae (pea family) is a big angiosperm family. Leguminosae is another name for the family, and legumes are the plants. It can be found all over the world. Many vital pulses are included, such as peas, soybeans, chickpeas, and others.

A floral formula is a symbolic depiction of various floral pieces, their quantity, the arrangement pattern, and their relationships. Pisum sativum (peas), a Fabaceae plant, with the fabaceae floral formula:

％ ⚥ K (5) C1+2+ (2) A (9) +1 G1

The symbols indicate the floral formula of fabaceae following:

• ％ – Zygomorphic (bilateral symmetry)

• ⚥ – Bisexual

• K(5)   – Calyx – 5 sepals, gamosepalous (united)
• C1+2+(2)     – Corolla – 5 petals, polypetalous
• A(9)+1   – Androecium – 10 stamens, diadelphous
• G1  – Gynoecium – monocarpellary, superior ovary

A floral formula is a symbolic depiction of various floral pieces, their quantity, the arrangement pattern, and their relationships. The floral of formula of solanaceae is:

⊕ ⚥ K(5)  C(5)A5  G(2)     

The symbols indicate the following:

⊕ – Actinomorphic (radial symmetry)

⚥ – Bisexual

K(5)   – Calyx – 5 sepals, gamosepalous (united)

C(5)    – Corolla – 5 petals, gamopetalous

A5      – Androecium – 5 stamens, polyandrous (free), epipetalous (attached to    petals)

G(2)   – Gynoecium – bicarpellary, syncarpous (united), superior ovary

A floral formula is a symbolic depiction of various floral pieces, their quantity, the arrangement pattern, and their relationships. Allium cepa (onion), a Liliaceae family member, has the following floral formula of liliaceae:

                                         Br ⊕ ⚥ P(3+3) A3+3  G(3)

The symbols indicate the following:

Br – Bracteate

⊕ – Actinomorphic (radial symmetry)

⚥ – Bisexual

P(3+3)  – Perianth – 6 tepals in two whorls, gamophyllous (united)

A3+3 – Androecium – 6 stamens, polyandrous (free), epiphyllous (attached to tepals)

G(3)  – Gynoecium – tricarpellary, syncarpous (united), superior ovary

Family Fabaceae Characteristics

The Fabaceae family has the following morphological and floral traits.

Characteristics of a Plant

1. Taproot with root nodules, dicotyledons’ root.

2. Fabaceae includes shrubs, herbs, trees, and most notably climbers, and their stems are either erect or climber.

3. Petiolate, pinnately complex or simple leaves with stipulated pulvinus leaf base and reticulate venation.

Characteristics of flowers

1. Racemose inflorescence

2. Bracteate/ ebracteate, complete, bisexual, zygomorphic, hypogynous flower.

3. Calyx: Gamosepalous with five sepals; valvate or imbricate aestivation.

4. Corolla: vexillary aestivation, five petals, polypetalous, papilionaceous.

5. Androecium: diadelphous, anther dithecous, ten stamens (9+1).

6. Superior ovary, monocarpellary, unilocular, single, short-style and flat, hairy-stigma Gynoecium: Superior ovary, monocarpellary, unilocular, single, short-style and flat, hairy-stigma Gynoecium: Superior ovary, monocarpellary, un

7. Legume is the name of the type of plant that produces the fruit.

8. Non-endospermic seed: one or more.

Economic Importance

Several plants in this family have commercial value. Here are just a few of them:

• This family of plants is remarkable in that it has nitrogen-fixing symbiotic bacteria in its root nodules, which may convert atmospheric nitrogen into fixed nitrogen or ammonia.

• The main food sources are pulses including gramme, moong, and soya bean.

• The medicinal potential of the Mulethi plant is well-known.

• Cooking oil is extracted from soya bean and groundnuts.

• Sunn hemp provides both wood and fibre.

• Indigofera is a plant that is used in the production of dye.

• Fodder or livestock feed can be made from Sesbania and Trifolium.

• Ornamental plants like lupin and sweet pea are common.

Conclusion 

Hence, the Fabaceae family is a vast plant kingdom family that includes a number of economically significant species. Because it belongs to the legume or pea family, the Fabaceae family is often known as Leguminosae or Papilionaceae. Dicotyledonous Fabaceae plants are found all over the world and number over 20,000 species.
