The yarpick is commonly known as the daggerthorn. It is a shortish, sturdy tree with low, spreading branches and broad, fringed leaves. Its trunk has relatively small, exceedingly sharp thorns about one-half foot long. Thorns on its larger branches can be awesome, the largest growing to over two feet in length and as thick as a finger at the base. Yarpick thorns are tough and straight and have been used as weapons or weapon components. The mature tree bears small fruit which is not useful, but the inner seed is quite good when cracked as if a nut. Cultivated yarpick " nuts" are as large as plums and very wholesome and nourishing. The meat is eaten roasted or ground into meal.
