Yucca treculiana Carrière [4] is a species of flowering plant in the family Asparagaceae, native to Texas, New Mexico and Coahuila. [5] Common names include Spanish dagger, Spanish bayonet 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. [6] [7]

In the last three generations, it has experienced a population decline of 30 percent, attributable due to habitat loss. [2]

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." [8]
