Stenocactus

Peculiar species distinguished for its small sized yellowish blooms, very short flattened foliaceous central spines and few radial spines.

Solitary stem yellowish-green to dark olive-green. Ribs are very regularly and attractively wavy. Radial spines 4–6, glassy-white; central spines 3, strongly flattened, brownish-purple, upright, with one distinctly longer.

Mix of Echinofossulocactus (Stenocactus), assorted with various species and seed-grown hybrids. Each plant is one-of-a-kind, featuring unique shapes, spination, and flower colors.

White-woolly depressed apex. Rounded stems with about 35 slender ribs featuring sharp, wavy edges. Radial spines are bristle-like, silky, near-transparent (whitish-cream), while centrals are thicker, longer, and amber to tan-colored.

Very long, flat, and papery spines. A stunning plant even when not in bloom. Flowers white and feature a pink midline on the petals. Previously classified under different names, such as E. multicostatus, E . zacatecasensis and E.phyllacanthus.

Numerous wavy ribs topped with long, sturdy central spines. Flowers feature pale, pearly petals, each marked by a central stripe and a soft pink throat, creating a delicate, luminous effect.

When young, it produces areoles densely packed with spines, which gradually reduce with age to 3–5—featuring a single strong, flattened central spine that points upward. The white flowers are enhanced by a purple stripe running down the center of petals.

Variegated plants with yellow-tinged epidermis. Grown from seeds of variegated parents.

Showy pink-violet blooms paired with remarkable spines—central ones begin short but elongate and flatten dramatically as the plant ages, creating a unique silhouette.

Thirteen broad, flat ribs and stout spines. Echinofossulocactus coptonogonus stands out as the most unusual and easily identifiable species in the Stenocactus group, with a compressed stem and straight, wide ribs reminiscent of Homalocephala texensis.

A globular plant with slender, undulating ribs and striking upright central spines—long, sword-like, and deep red-brown in color. Notably beautiful specimens.

Ball-shaped cactus with wavy-margined ribs. White areoles bear 5–12 spines, the upper one flattened and wide, reddish-brown. Spring-blooming with pale yellow to pink flowers, each petal featuring a purplish-red stripe.
