Commonly called the daggerthorn, the yarpick is a shortish, sturdy tree with broad, fringed leaves. Its nickname comes from the frightfully sharp thorns that radiate from its trunk and branches, which can grow anywhere from half a foot to two feet in length. Yarpick thorns have been used as weapons.

Yarpick fruits are not edible, but its plum-sized inner seed is nutty and nutritious, eaten roasted or ground into meal.
