Corryocactus erectus grows semi-prostrate to upright, is only slightly branched and reaches heights of up to 1 meter. The slender, cylindrical shoots have a diameter of up to 3 centimeters. There are five to nine narrow, not very prominent ribs. The eight to 18 bright, unequally long thorns that radiate in all directions have a darker base and cannot be differentiated into central and peripheral thorns. They are up to 1 centimeter long.
The light red to vermilion flowers are 2.5 to 4 centimeters long. The bright red fruits reach a diameter of up to 2 centimeters.[2]
Corryocactus erectus is widespread in Cusco, Peru.
The first description as Erdisia erecta was made in 1942 by Curt Backeberg.[3] The specific epithet erectus comes from Latin, means 'upright' and refers to the upright shoots. Friedrich Ritter placed the species in the genus Corryocactus in 1981
