description

Echinocereus nicholii forms branched, large, loose groups from the base, which consist of up to 30 shoots . The upright, cylindrical shoots are 30 to 60 centimeters long and 5 to 7 centimeters in diameter. There are ten to thirteen ribs that are not clearly humped. The strikingly long central spines are glassy white or clear golden yellow. The two to six central spines, rarely up to eleven, are straight and stiff. The lowest of them has a length of 5 to 6.2 centimeters. The eight to twelve (rarely up to 18) radial spines are spreading, straight and 0.8 to 1.2 inches long.

The funnel-shaped flowers are red to blood red. They appear in the upper half of the shoots, are 5 to 6.2 inches long and reach the same diameter. The egg-shaped initially green fruits later turn red and are covered with sloping thorns.
