Selenicereus calcaratus

A climbing cloud-forest cactus endemic to Costa Rica. It has broad, three-winged, deeply lobed stems with almost spineless areoles. It grows near the continental divide at about 1,700 m, so it needs cool-to-mild temperatures, constant humidity and filtered light rather than desert conditions.

Where it grows wild

Montane cloud forest on both slopes of the central cordillera, where it climbs and scrambles over trees and rocks using aerial roots. Its exact flowering behaviour is poorly documented.

Recorded from 1,200 to 1,750 m, median 1,650 m. One 40 m lowland record is doubtful.
