A simple, but very meaningful representation of the building of blooms is in the bloom formula. The building of blooms of a kind, a kind or a family is represented thereby by symbols. As is the case for a bloom diagram also interpretations, like the loss of organs, can secondary Vermehrungen, etc. be represented also here apart from the actual conditions.

Meaning of the symbols

  • P = Perigon
  • K = cup (Calyx)
  • C = crown (Corolla)
  • A = Androeceum (whole of all Sex organs (=aller
  • G = Gynoeceum (whole of all weibl. Sex organs (=aller inclusive stamps))

In the bloom formula further information stands apart from the above letters deeply placed:

  • A number, which indicates the number of respective members. For example K_3 stands for three At landlord leagues blooms each petal circle is separately regarded. At an indefinite number (meant is more than 6) in a petal circle an infinity character is used \ infty.
  • Growing together in parentheses represented, for example is located to G_ {(3)} for three grown together or [C_ {(5)} \; A_4 grew together with one another] if the Kron and
  • A placed in front star \ star marks a bloom (aktinomorph).
  • An arrow directed downward \ downarrow symbolizes a zygomorphe bloom (only one symmetry axis).
  • A line indicates the position of the Fruchtknotens above or down. Examples are G_ {\ overline3} for under constant and G_ {\ underline2} for upper constant.
  • A vertical line | marks a separation by additional septa.

Here a table with some examples of bloom formulas:

(Lamiaceae)\ downarrow K_ {(5)} \; [C_ {(5)} \; A_ {4-2}] \; G_ {\ underline {(|2)}}
(Apiaceae)\ star K_ {5-0} \; C_5 \; A_5 \; G_ {\ overline {(2)}}
Cross bloom plants (Brassiceae)\ star K_4 \; C_4 \; A_ {2+4} \; G_ {\ underline {(2)}}
Lily plants (Liliaceae) and (Juncaceae)\ star P_ {3+3} \; A_ {3+3} \; G_ {\ underline {(3)}}
(Cyperaceae)\ star P_ {3+3} \; A_ {3-0} \; G_ {\ underline {(3)}- \ underline {(2)}} or P_0 \; A_ {3-0} \; G_ {\ underline {(3)}- \ underline {(2)}}
