Escobaria abdita ssp. tenuispina takes its name from the Latin word "abdita" meaning "hidden/invisible", due to its particular tendency, in its natural habitat, to hide among the cracks in the ground during drought periods. Its typically solitary stem is globular and of a dark green color. It has numerous elongated tubercles, on the apices of which grow thin ivory-white spines arranged geometrically in a comb shape. It produces pale pink bell-shaped flowers.
