description

Echinocereus scheeri usually grows with numerous shoots sprouting from their base and sometimes forms upright, but mostly spread out or creeping groups. The cylindrical shoots are tapered towards their tips. They are 10 to 70 centimeters long and 1.5 to 4 centimeters in diameter. There are four to ten clearly blunt ribs , straight and occasionally tubercular on their sides. The up to four white to brownish central spines , which can also be missing, have lengths of 0.1 to 2 centimeters. The usually 6 to 13 white to light brown radial spines are 1 to 7 millimeters long.

The tubular-funnel-shaped flowers are pink to orange to scarlet. They appear along the sides of the shoots from sharply tipped buds, are 6 to 12 inches long and reach 4 to 6 inches in diameter. The short egg-shaped fruits are bright green and contain white pulp . They tear open lengthways and are covered with slightly sloping thorns.
