Description
[edit]Oreocereus doelzianus grows as a shrub with richly branched, cylindrical, olive-green shoots from the base and reaches heights of growth of up to 1 meter with a diameter of 6 to 8 cm (2.4 to 3.1 in). There are 10 to 11 ribs that are somewhat contracted between the gray felted areoles. The spines are yellow to dark brown. The four crossed central spines are strong and up to 4 cm (1.6 in) long. The 10 to 20 radial spines are up to 3 cm (1.2 in) long. The terminal cephalium consists of long, white, wavy hairs and whitish-yellow bristles up to 5 cm (2.0 in) long.
The carmine-red flowers have a bluish tinge and appear from the cephalium. They are up to 10 cm (3.9 in) long and have a diameter of 3 cm (1.2 in).[2]
