- A treelike plant(Yucca brevifolia) of the southwest United States, having sword-shaped leaves and greenish-white flowers grouped in large panicles. 短叶丝兰，约书亚树：产于美国西南部的一种树状植物（短叶丝兰 丝兰属） 长有剑形叶，开有淡绿色花，花为圆锥状大花簇
- Probably after Joshua [from the resemblance of the tree's greatly extended branches to Joshua's outstretched arm as he pointed with his spear to the city of Ai (Joshua 8:18)] 可能源自 Joshua[因为这种树的树枝伸展得很开，好象约书亚用长予指向艾城时伸出的手臂（《约书亚记》8：18)]
