1. Their seeds have only one cotyledon.
2. Leaf veins are parallel.

4. root root.
5. The location of the carpels is apical and the embryo is lateral.
6. Seed coat and fruit coat are attached together.
7. The flowers are incomplete and the perianth remains.
8. The vascular bundles of the stem are scattered. Cambium tissue is absent.
9. Secondary growth does not occur.
10. Pollen monocolpate (one grooved).

Herbaceous plants whose seeds have only one cotyledon are called monocots. The family of monocotyledonous plants is called monocotyledonous family. Dr. Arthur Cronquist (1981) grouped all herbaceous plants into 380 genera. Among them, the number of monocots is 65. Butomaceae is the first family of monocots, Poaceae is the 34th family and Orchidaceae is the last 65th family.

The axis from which flower is formed is called mother axis. The side opposite to where the flower is attached is called Axis.

Sepals 5 and free, sepals 5, connate, and valvate, petals 5, free and twisted, stamens numerous, gregarious and connate, anthers free, carpel subgynate, 5-celled, carpels 5 and connate, anthers axillary. Floral symbols indicate that the flower is polysymmetric, bisexual and pentamerous.

Anthers and subanthers present, carpels 2 and free, stamens 6, 3 in two whorls and free, ovary subgynous, 1-chambered and carpel 1. Arrangement is key. The floral symbols show that the flower is unisexual, bisexual and trimerous.

The diagram that shows the gender of the flower compared to the mother axis, the different stanzas, the number and position of members of each stanza, their synergism or dissociation, the presence or absence of stamens, floral arrangement, amara arrangement etc. is called Floral diagram. In 1778, the German botanist August Wilhelm Aicher described the first floral symbols.

Flower polysymmetric and both sexes, sepals 5 and free, sepals 5 and connate, petals 5 and free, stamens numerous, gregarious and connate, ovary superior, 5-chambered, carpels 5 and connate.

Sepals and sepals present, flower unisexual and bisexual, pistils 2 and free, stamens 6, 3 each furnished with two whorls and free, ovary superior, 1 chambered and carpel 1.

1. First write the alphabet of submanjaripatra.
2. Then write the alphabet of Manjaripatra.
3. If the flower is symmetrical or polysymmetric, its signal should be written.
4. The flower is unisexual or bisexual.
5. Specify whether subscripts are alphabetic, numeric, and free.
6. Vocabulary is written with letters, numbers, and whether it is joined or not.
7. Specifying the alphabet, number and whether the group is connected or free.
8. Pushpaput alphabets, numbers and compound or free should be written.
9. Mention the alphabet, number and whether attached or free of stamens.
10. Its signal is not underground or underground.
11. Zero (0) is written if Vriti, Dalmandal, Pungstavak and Stristavak are absent.
12. The flower is a sign of symmetry or disharmony.

The signal with the help of which the gender of the flower, the different stanzas, the number and position of members of each stanza, their concordance or disconcordance, the presence or absence of stamens etc. is expressed
