Form (botany)

The abbreviation "f." or the full "forma" should be put before the infraspecific epithet to indicate the rank.

For example: A form usually designates a group with a noticeable morphological deviation.

[2] For instance, white-flowered plants of species that usually have coloured flowers can be grouped and named (e.g., as "f. alba").

Formae apomicticae are sometimes named among plants that reproduce asexually, by apomixis.

There are theoretically countless numbers of forms based on minor genetic differences, and only a few that have particular significance are likely to be named.
