Central Spines
0 - 1, up to 35 mm long, brown-black, stiff and straight.
Seeds
1-1,5 mm black.
Description
Usually solitary.
Roots
Fibrous.
Note
Adult plants, either without central spines, or with 1 central spine can be found. But with the exception of the absence or existence of centrals, all the other characteristics are absolutely identical, namely size and form of ribs, number, size and arrangement of radial spines, flowers, fruits and seeds. Furthermore this species is one of those Echinocereus which pass a purely radial-spined long youth stage, in which they are already floriferous. Most of the plants after several years develop central spines, giving the plant its sea urchin appearance.

Ribs
11 to16, 5-12 mm long
Stem
Green, short, cylindrical, up to 20 cm tall 4(12) cm in diameter.
Radial Spines
5-18, pectinated 16-23 mm long. Cream with darker tips add-pressed.
Fruits
Ovoidal, brownish-green, length15, diameter 10. They dry and break at maturity and ripe in 2 months.
Areoles
Ellipsoidal, length 3–4mm, width 2 mm, close set, distance 4-7 mm, at first woolly, then naked.
