Description: E. crispatus is a solitary plant (or rarely branching) closely covered with very long spines and wavy ribs. This is a very variable species that now includes many form (previously considered independent species) with one form intergrading into another, creating a taxonomig nightmare. It is one of the Echinofossulocactus with the prettiest spination.
Stem: Up to 20 cm tall, 10 cm wide, globose, short-cylindric or obovoid, somewhat depressed at apex, light green to olive-green.
Ribs: (25-)30-60(-80) thin with very regularly and attractively waived, depressed in the region of areoles. The flattened, waivy or curled ridged of this species are characteristic of other kinds of Echinofossulocactus.
Areoles: 1 to 3 in each ribs, woolly in youth, later naked.
Radial spines: Usually 4 to 6 flattened, whitish to brownish, 0,5 to 1 cm long and about 0,6-1 mm wide at the base.
Central spine: 3-4 very flattened, whitish, yellowish, brownish to almost black, often darker at the tip, directed upwards ± rigid, ferocious-looking, straight or curved, unequal with one very long (from 1 to 10 cm long) and 1-5 mm wide at the base. The var. longispinus (from Latin Longi spinus = Having long spines) is characterized by very long flattened spines and is very decorative.
Flowers: Central, funnel-shaped rather small, perianth segments in two series, pale pink with a purplish midrib, oblong-linear, acute. Flower tube covered with imbricated scales.
Blooming season: Late spring to summer.
Fruit: 8-12 mm long, 4-6 mm wide, obovoid reddish to greysh, dry at maturity.
Seeds: 1 mm long x 0,9 mm wide, pyriform to reniform, black. Head with celled and wavy wall.
 

A 15 years old specimen with perfect spination, but for such a spines need a lot of sun.
