Yucca treculiana Carrière is a species of flowering plant in the family Asparagaceae, native to Texas, southern New Mexico, Coahuila, Nuevo Leon, and Tamaulipas. Common names include Spanish dagger, Spanish bayonet, Trecul's Yucca, and Don Quixote's lance.
Yucca treculiana is a large, tree-like species up to 10 m (33 feet) tall, often branching above the ground. Leaves are up to 128 cm (50 inches) long. Flowers are cream-colored, sometimes tinged with purple. Fruits are fleshy and succulent, up to 19 cm (7.5 inches) long.
In the last three generations, it has experienced a population decline of 30 percent, attributable due to habitat loss.
Some sources list this species as "Yucca spinosa Kunth." However, the type specimen for this name at the herbarium in Berlin appears to be Dasylirion sp., thus rendering the name a "nomen confusum."
