Selenicereus setaceus is a species of plant in the genus Selenicereus from the cactus family(Cactaceae).

description

Selenicereus setaceus grows epiphytically or lithophytically with long, overhanging, light green, mostly triangular (rarely square or pentagonal) shoots 2 to 3 centimeters in diameter, which are slightly flared at the edge. From the slightly raised areoles , 2 to 3 centimeters apart, arise 2 to 4 conical, reddish thorns , which later turn brown and are 1 to 2 millimeters long.

The 25 to 30 centimeters long flowers are white with a yellowish base and greenish on the outside. The conspicuously tuberous pericarpel is covered with felt wool and short thorns. The flower tube is covered with bare scales. The edible fruits are egg-shaped and have a few bristles. The initially green, heavily tuberous fruits turn red when ripe and are then almost undone.
