花程式的表达
为直观、简捷地表达植物花的结构,常用以下两种方式。
花程式:用花的各部分的英文或拉丁文的第一个字母来表示花各部,并按从里到外的原则描写花的构造。以蔷薇科苹果属和蝶形花科刺槐属的花程式为例来解释:
苹果属(Malus) *Ca5Co5A∞G(5:5:2) 或 *K5C5A∞G(5:5:2)
刺槐属(Robinia) ↑Ca5Co5A10G(1:1:∞) 或 ↑K5C5A10G(1:1:∞)
* = 花冠辐射对称(actinomorphic);
↑ = 花冠两侧对称(zygomorphic;
♂ = 雄花(male unisexual flower);
♀ = 雌花(female unisexual flower);
Ca(K) = 花萼(calyx: or whorl of sepals);
Co(C) = 花瓣:(corolla: or whorl of petals);
CaCo或P = 花被(perianth:if sepals and petals are alike termed "tepals");
A = 雄蕊(群)(Androecium: or whorl of stamens);
G = 雌蕊(群)(Gynoecium: or ovary bearing carpels);
∞ = 多数(many);
数字 = 花各部数目;
G() = 心皮合生(fully fused carpels);
G = 子房上位(ovary inferior to insertion point of the other whorls.The floral whorls are
hypogenous to the gynoecium);
G = 子房下位(ovary inferior to insertion point of the other whorls. The floral whorls are
epigynous to the gynoecium);
G = 子房半下位(ovary inferior to superior-variation exists within the family; or half
inferior);
CaCo or CoA = 花萼与花瓣或花瓣与雄蕊联合(adnate; or fusion of two different floral
Whorls)。
