The crested shape of this cactacea presents the typical fan arrangement, which makes every specimen unique, never identical to another one and, for that reason, beloved by collectors. In its regular shape it is a magnificent specimen of solitary cactus, with a dark green globose stem with a yellowish-white down at the apex. It has numerous well-marked and wavy ribs, on which we find the white and wooly areolas. From the latter emerge the radial and central spines curved upwards: the former are thin, yellowish-white and short, while the central ones are very robust, long and yellow with dark tips. E. guerraianus is also known by the name of Stenocactus guerraianus and is suitable for all types of locations that enjoy a lot of brightness.
