银杏
古老银杏类植物谱系的唯一现生代表
银杏是银杏类植物中现存唯一物种，也
是银杏目延续至今的唯一代表。它属
于古老的裸子植物谱系，具有独特的
扇形叶片、典型的二叉分脉结构以及
雌雄异株的繁殖特征。银杏类植物曾
广泛分布于中生代陆地生态系统，而
现代银杏保留了这一古老类群的重要
形态特征。由于其悠久的演化历史和
独特的生物学特征，银杏常被称为“活
化石”。如今，原产于中国的银杏，并已
被广泛栽培于世界各地。
Ginkgo biloba
The Only Living Representative of an Ancient Ginkgo Lineage
Ginkgo is the only living species of the ginkgo lineage and the 
sole surviving representative of the order Ginkgoales. It 
belongs to an ancient lineage of gymnosperms and is 
characterized by its distinctive fan-shaped leaves, 
dichotomous venation, and dioecious reproductive system. 
Ginkgoales were once widely distributed in terrestrial 
ecosystems during the Mesozoic, and modern ginkgo retains 
many important morphological features of this ancient group. 
Due to its long evolutionary history and unique biological 
characteristics, ginkgo is often referred to as a “living fossil.” 
Today, ginkgo is native to China and has been widely 
cultivated around the world.
