Monatschrift für kakteenkunde 19: 188, (1909).

Radial spine: 20 - 26, 1 - 3 mm long, bristle-like, somewhat horizontal radiating, white.
Central spine: 0 - 2, sometimes one pointing upwards and longer, 1 - 3 mm long, awl - shaped, straight, smooth, thicker and dark brown at base, brown with black tip.
Flower: Funnelform, 10 - 12 mm long and in diameter, carmine pink with darker midstripe.
Fruit: Club-shaped, deep dull pinkish-red, 10 - 15 mm long and 2 - 3 mm wide. Ripens 7 months after flowering. Selfsterile.

Habitat Substrate: Between rocks in humus soil.
Geographic Distribution: Mexico; Queretaro near Higuerillas, San Luis Potosi near Realejos. Altitude 1500 - 2800 meu
Comments: Psuedoperbella was unfindable for years. But founded back later by Wendel Minnich in Queretaro, let's hope it will one day be accepted as being a good species. Pseudoperbella is not a rarity in our collections and seems to be true to the description.
