Acharagma roseanum is a succulent cactus native to a small area of mountains of southeastern Coahuila and Nuevo León, Mexico. It grows on rocky limestone hills and xerophytic shrubland.[1] Its name is often misspelled as "Roseana".[2]
Description
Acharagma roseanum forms individual, small, soft bodied cacti that form clusters over time.[2] The plant's specific physical characteristics are: The stem is 4–6 cm (1.6–2.4 in) tall, 1.5–5 cm (0.59–1.97 in) wide with spines that are white-yellow to gold color. The warts stand in rows and are up to 0.3 centimeters long. The 4 to 6 yellow central spines are very similar to the marginal spines or are slightly curved and are 1 to 2 centimeters long. The 15 to 30 marginal spines are yellowish to brownish and 0.8 to 1.5 centimeters long. The flowers are pink to bronze with a dark reddish central stripe or cream flowers on the top of the stem, 1.5–2 cm (0.59–0.79 in) in diameter.[3]
Distribution
Acharagma roseanum is widespread in the Mexican states of Coahuila, Nuevo León and San Luis Potosí.
