Description: This small, perennial, epiphytic cactus has a narrow, shrubby habit and reaches 15 in (38 cm) in height and spread. The slender, tubular stems readily branch and are totally spineless. In spring tiny, deep yellow flowers appear at the bloated stem tips. Maintain moisture during the hotter months and water only occasionally during winter.
Culture: Plant these frost-tender cacti in porous soil in full sun or part-shade. Propagate from cuttings or seed. Prune when required.
