xenogamy 的词源

在植物学中，“异花授粉，来自同种不同植物的花粉授粉”，1877年，来自xeno-“奇怪，外国”+ -gamy“授粉”。相关词：Xenogamous。

由Anton Kerner von Marilaun在德语中引入，他的著作英文版名为《Flowers and their Unbidden Guests》，作为他描述系统中的一个术语，在脚注中解释：

I understand by autogamy the fecundation of a flower by the pollen from the androecium of the same flower ; by geitonogamy, the fecundation of a flower by pollen from other flowers on the same plant ; by xenogamy the fecundation of a flower by pollen from other plants. Geitonogamy and xenogamy may be classed together under the name allogamy. Such terms as "self-fertilisation" are to be avoided on account of their excessive indefiniteness.

我理解自花授粉是指花朵由同一花的雄蕊花粉授粉；而邻近授粉是指花朵由同一植物上其他花的花粉授粉；异花授粉是指花朵由其他植物的花粉授粉。邻近授粉和异花授粉可以统称为异交授粉。诸如“自我授粉”的术语应避免使用，因为它们过于模糊。
