Generally, the flower parts should be written in the order in which they are arranged from outside to inside. Each part of the flower is generally represented by the first letter of the Latin noun (calyx is in German): P----Perianthium) K----Calyx (Kaiyx) C----Corolla ) A----stamen group (Androecium)G----pistil group (Gynoecium), the numbers 1----10 represent the number of each part of the flower in each round, and the numbers in each round are separated by +; ∞ represents the number More than 10 and indefinite; 0 means not available or degraded. These numbers or symbols are written on the lower right side of the representative letters. The first number on the lower right side of pistil group G indicates the number of carpels, the second number indicates the number of ovary chambers, and the third number indicates the number of ovules per chamber (usually only the first number or the second number is used), Each number is separated by :. () indicates conjunction and is enclosed outside the numbers. -Indicates the position of the ovary. For example, G means that the ovary is superior, otherwise it means that the ovary is inferior. The middle line between the upper and lower lines means that the ovary is semi-inferior. * or ⊕ means neat flowers, ↑ or % means irregular flowers, write them in front of the flower program. ♀ represents female flowers, ♂ represents male flowers, and ♀♂ represents bisexual flowers. They are also written in front of the flower program, sometimes omitted. P refers to single perianth flowers, and those with K and C refer to double perianth flowers. Double perianth flowers are generally not pronounced. 1.
