Flower ceremony - Kasiki

Japanese: 花式 - かしき
Flower ceremony - Kasiki

A formula expressing the structure of a flower. For example, the perianth is P, and if the perianth has a distinction between the calyx and the corolla, the calyx is K, the corolla is C, the stamens are A, and the pistil is G, and the number of leaflets that make up the structure is indicated by a number. Usually, the attachment of leaflets is indicated by parentheses, and various symbols may be used to indicate the superior or inferior position of the ovary and other characteristics.

In contrast to the floral formula, a floral diagram is a diagram of the cross section of a flower seen from above, in order to clearly show the number and positional relationship of the leaves. The cross section of the ovary is shown to show the number and position of the carpels that compose the pistil. Axillary flowers are drawn with the adaxial side facing up.

Japanese:

花の構成を式で表現したもの。たとえば、花被(かひ)をP、花被のうち萼(がく)と花冠の区別のあるものでは、萼をK、花冠をC、雄しべをA、雌しべをGとし、それらを構成している花葉の数を数字で示す。普通は花葉の合着は括弧(かっこ)で示し、さらに子房の上位または下位、その他の特徴を示すためにいろいろな記号を用いることもある。

 花式に対し、花葉の数と位置関係を簡明に示すように、花の横断を上から見たところを模式化したものを花式図という。雌しべは、それを構成している心皮(しんぴ)の数や位置を示すために子房の横断を示す。腋生(えきせい)している花は向軸(こうじく)側を上にして描く。
