Deamia montalvoae

A climbing or hanging forest cactus recorded at about 1,500–1,600 m in El Salvador and Guatemala, with additional range in southeastern Mexico. It grows on trees and rocks in seasonally humid montane forest, so it needs bright shade, mild temperatures and an epiphyte-style mix rather than desert conditions.
