Description
[edit]Oreocereus tacnaensis grows as a shrub with erect or spreading shoots that branch from the base. The blue- to gray-green shoots are up to 3 meters long and have a diameter of 4 to 8 cm (1.6 to 3.1 in). There are 10 to 16 notched ribs. The spines arising from the areoles are reddish brown to brownish yellow. The four to eight central spines are straight to slightly curved and 3 to 6 cm (1.2 to 2.4 in) long. The 12 to 30 needle-like radial spines are straight and up to 1 cm (0.39 in) long.
The crooked-edged flowers are brownish red to blood red and 8 to 11 cm (3.1 to 4.3 in) long. The spherical fruits are yellowish to brownish yellow and have a diameter of 3 to 4 cm (1.2 to 1.6 in). When fully ripe, they tear open from the tip and release the seeds.[2]
