Oreocereus pseudofossulatus is a species of Oreocereus found in Bolivia.^[2]

Description

Oreocereus pseudofossulatus grows shrubby, branches irregularly in the lower half and reaches heights of up to 2 meters. The light green shoots have a diameter of 5 to 8 cm (2.0 to 3.1 in). There are 10 to 13 straight and tuberous ribs. The spines are straw yellow or rarely reddish. The single, conspicuous central spine, 2 to 5 cm (0.79 to 1.97 in) long, is initially protruding and later directed slightly downwards. The 10 to 14 radial spines are up to 6 mm (0.24 in) long.

The tubular, crooked-edged, greenish pink to bluish red flowers appear near the tips of the shoots and are up to 9 cm (3.5 in) long. The ellipsoidal, greenish yellow to brownish red fruits are fleshy and do not tear.^[3]
