Explanation:

The flower formula is a word that gives an idea of ​​a flower structure. It also provides a better view of the genus and plant phylum. The flowers of the Brassicaceae are distinguished by their proportions and the presence of reproductive organs, so their flower formula will also vary.

A flower formula is a word that describes the formation of a flower using various letters, numbers, and symbols. Provides information on the balance, sex, and affinity of various flower components such as calyx, corolla, androecium, and gynoecium in an integrated way.

Mustard flowers are actinomorphic (show radial symmetry), rarely zygomorphic, hermaphrodite (with male and female flowers), consisting of four sepals in two whorl (dimerous), four-leaf, diagonally arranged- cruciform, six stamens.  tetradynamous (where the stamens are two small lateral and four large median), with bicarpellary gynoecium and parietal placentation, syncarpous, and bilocular due to the formation of a false septum or replum.

Brassicaceae or Cruciferae are often called mustard, cabbage family, or crucifers.

- The flower formula extends from bract and bracteole to symmetry and flower sex, calyx, corolla, androecium, and gynoecium. The number of parts of each organ is indicated by numbers (1, ..., 4, 5) after the correct letters of the alphabet (K, C, A, G).

- The number placed just after the symbol as in the text below represents the number of parts in that situation. When whorl components are connected the number is in parentheses. For example, if four free sepals are present in whorl they are defined as K4 and when combined, they are defined as K (4). If there is more than one whorl, it is represented as a total of whorls. If there are four free sepals present in two whorls each, it is represented as K4 + 4.

- Groups of members can be represented by writing the number of events in the group as the text above. For example, A52 refers to five groups of two stamens.

Note: - The flowers of the Brassicaceae are independent and cross-pollinated. Some species show cleistogamy while other flowers attract insects.

- Flower inflorescence can be raceme, corymb, or corymbose raceme.

- The fruit is siliqua or lomentum.
