CACTACEAE (Cactus Family)
The generic name refers to Opus, an ancient Greek city that was fabled to have "a spiny-type plant growing at the outskirts." The specific epithet refers to the lake or "lagoon" at the top of the Sierra de la Laguna to which this species is restricted. Another common name is "Tuna Morada," a reference in Spanish to the color of its fruit.
This cactus is in the prickly-pear group of the genus Opuntia and grows approximately 1 m (3 feet) high. The stems are flattened and oval in shape, typical of the pads of many prickly-pears. The pads are gray-green and glaucous in color. The white spines are 3 cm (1-1/4 inches) long. The flowers have yellow petals and are approximately 7 cm (almost 3 inches) wide. The fruit is 7 cm long, and a deep red in color. It is very sweet in flavor.
Range and Habitat
This nopal is restricted to only one mountain range of Baja California Sur in the highest part of the Sierra de la Laguna. It grows at approximately 2000 m (6600 feet) in elevation.
