Echinocactus wislizeni Engelm.

Western North America. This cactus is called by the Mexicans visnada, or biznacha. The seeds are small, and black and when parched and pulverized, make good gruel and even bread. The pulp of the fruit is rather sour and is not much eaten. Travellers, in passing through the cactus wastes, often resort to this plant to quench their thirst, its interior containing a soft, white, watery substance of slightly acid taste, which is rather pleasant when chewed. Pieces of this, soaked in a sirup or sugar and dried, are as good as candied citron, which they resemble in taste and substance. This plant, in some of its preparations, furnishes a favorite food to the Yabapais and Apache Indians of Arizona.
