Vegetative characters

Habitat: Members of this family are adapted to conditions that encourage heavy concentrations of essential oils.

Habit: Most of this family are herbaceous annual, biennial (having a 2 year cycle), or perennial plants

Root system: These plants have tap root system. The roots are large enough to store the useful food materials. For example: carrot and parsnip.

Stem: Stems are hollow at the points where the leaves are attached. Usually stems are soft, green, aerial. Either prostrate or erect. Sometimes stems penetrate underground and store food materials. The nodes of the stem are swollen.

Leaf: Leaves are alternate, exstipulate, pinnately compound or palmately lobed with reticulate venation. Leaf petiole is broadened with sheath surrounding stem or base of leaf.

 

Floral characters              

Inflorescence: Inflorescence is the characteristic feature of this family. The flowering head is usually a simple or compound ‘umbel’, but it can be reduced to a single flower in some species. This flat-topped umbel resembles a flattened umbrella structure and thus the alternate name for this family is Umbelliferae. The primary umbel is surrounded by an involucre of bracts and secondary umbel is subtended by an involucre of bractlets.

Flower:Flowers are small, bracteate/ebracteate, pedicillate or sessile, complete, regular, pentamerous, actinomorphic or zygomorphic, epigynous, cyclic usually bisexual and rarely unisexual. Flowers are arranged in umbels or double umbels, Flowers are many, small, white or yellow in color.

Calyx: The calyx consists of 5 sepals which remain adnate to the ovary wall. Sometimes sepals may be absent. The aestivation is valvate. The calyx is usually represented by five inconspicuous teeth.

Corolla:The corolla consists of 5 free petals alternating with sepals. Petals are usually apically inflexed in bud and they fall off soon. The aestivation is imbricate or valvate. The petals are two lobes. The peripheral flowers of Coriandrum have unequal petals.

Androecium: The Androecium consists of 5 free stamens, alternating with the petals. They arise from an epigynous disc. The filaments are equal in length, inflexed in bug and the anthers are basifixed or dorsifixed, dithecous, introse and dehisce longitudinally.

Gynoecium: The Gynoecium is bicarpellary and syncarpous with an inferior bilocular ovary. Each carpel has a single pendulous and anatropus ovule. The placentation is axile. An epigynous disc called as stylopodium, is present on the top of the ovary. Stylopodium surrounds the two styles. Stigmas are capitates and distinct. The carpels are ribbed and have parallel resinous canals called vittae.

Pollination: Flowers are pollinated by a wide variety of insects – mostly flies, mosquitoes or gnats, bees, butterflies or moths.

Fruit: The fruit can be divided into 2 parts. The fruit is schizocarpic cremocarp. A cremocarp is made up of two one-seeded carpels called as mericarps. Mericarps remain attached to the central axis known as carpophore. Mericarps are longitudinally ridged and in between the ridges resinous or oil ducts called vittae are present.

Seed: Seeds are endospermic with a small embryo. The endosperm may be flat, crescent or concave on the ventral side.

Economic Importance of Apiaceae

The family Apiaceae contributes several important food, essential oils and aromatic herbs to human race. Hence this family is considered as economically important.

Apium graveolens: It is cultivated in Himalayas, Uttaranchal, Himachal Pradesh and South India. It is used as a vegetable. Its roots and seeds are used medicinally. The fruits are used for extracting valuable oil and the seeds are used as spices.

Coriandrum sativum: It is chiefly grown in Madhya Pradesh, Maharashtra, Karnataka, Bihar and Uttar Pradesh. The fruits and leaves are used as condiment and spice. The fruit of this aromatic herb is used as stimulant, carminative, stomachic and tonic.

Cuminum cyminum: It is grown in the Punjab and Uttar Pradesh. This plant gives aromatic fruits which are used as flavoring agents.

Carum carvi: It is cultivated in Bihar, Orissa, the Punjab, Bengal and Andhra Pradesh. The fruits are used as condiment. Its fruits are also used as stomachic and carminative.
