Ortegocactus is a rare cactus genus native to a small region of Oaxaca, Mexico. It forms small, rounded to slightly elongated bodies covered with closely spaced tubercles and delicate spines, which can give the plant a soft, textured appearance. Its pale green to grey-green colour and compact habit make it quite different from more heavily spined desert cacti. Ortegocactus is valued for its rarity, restrained form and botanical interest, making it a notable choice for specialist cactus collections.
