Echinopsis cuzcoensis is a species of Echinopsis found in Peru.[2]

Description

[edit]

Echinopsis cuzcoensis grows tree-shaped with numerous, somewhat spreading branches and reaches heights of 5 to 6 meters. The cylindrical shoots are green. There are seven to eight low and rounded ribs. The areoles on them are 1 to 1.5 cm (0.39 to 0.59 in) apart. About twelve very strong, stiff thorns emerge from them and are swollen at their base. The thorns are up to 7 cm (2.8 in) long.

The funnel-shaped, white flowers are fragrant. They are open day and night. The flowers are 12 to 14 cm (4.7 to 5.5 in) long.[3]

[edit]

Echinopsis cuzcoensis is widespread in the Cusco region of Peru at altitudes of 3100 to 3600 meters.
