植物羊是一种传说中的植形动物，在古代中国 和欧洲典籍都有记载。

关于植物羊的称谓有很多，如英文中的“鞑靼植物羊羔”（Vegetable Lamb of Tartary或Tartar Lamb）、土生羊（earth born sheep）、斯基泰羊羔（The Scythian lamb）、Chinese lycopodium、叙利亚羊羔（syrian lamb）、水羊（water sheep）、Barometz、植生羊（planted sheep），拉丁文中的Agnus scythicus 、Planta Tartarica Barometz 等。

The Vegetable lamb of Tartary (Latin: Agnus scythicus or Planta Tartarica Barometz) is a legendary zoophyte of Central Asia, once believed to grow sheep as its fruit. The sheep were connected to the plant by an umbilical cord and grazed the land around the plant. When all accessible foliage was gone, both the plant and sheep died.
