ENGLISH: Wave Cactus, Brain Cactus
SPANISH (Español): Biznaga ondulada de muchas costillas
Description: Stenocactus multicostatus more often known as Echinofossulocactus multicostatus is a low-growing cactus with a lot of narrow, very acute and straight or wavy ribs, densely pleated together giving a wrinkled look to its near globular shape, with short 6 to 18 soft flattened brownish spines, arranged crosswise, but there is a great variation among plants of different origin both in spination, body shape and number of ribs. Since the various forms are connected by intermediates it is extremely difficult to recognize infraspecific taxa.
Habit: It is simple, but sometimes forms two or more stems.
