形态特征 :

    珙桐枝叶繁茂，叶大如桑，花形似鸽子展翅。珙桐的花紫红色，由多数雄花与一朵两性花组成顶生的头状花序，宛如一个长着“眼睛”和“嘴巴”的鸽子脑袋，花序基部两片大而洁白的总苞，则像是白鸽的一对翅膀，黄绿色的柱头像鸽子的嘴喙。当珙桐花开时，张张白色的总苞在绿叶中浮动，犹如千万只白鸽栖息在树梢枝头，振翅欲飞，并有象征和平的含意。因此称为“鸽子树”。

生长习性 :

    喜欢生长在海拔700～1600米的深山云雾中，要求较大的空气湿度。生长在海拔1800～2200米的山地林中

    珙桐有“植物活化石”之称，是国家8种一级重点保护植物中的珍品，因其花形酷似展翅飞翔的白鸽而被西方植物学家命名为“中国鸽子树”。
