原生地・分布（英語）:

説明（英語）: Genus of over 150 species of evergreen shrubs or subshrubs, with trailing or pendent shoots, and occasionally scandent climbers, found in moist woodland, rainforest, or cloud forest in the West Indies, Mexico, Central America, and tropical South America. In the wild, they are frequently epiphytic, and often branch where the stems are rooted into the humus; in cultivation, the stems tend to remain unbranched. They have pairs of usually ovate to elliptic, often hairy, dark green leaves. From spring to autumn, tubular flowers are borne singly or in small clusters from the leafÅ@axils. They are 5-10bed, with the upper 2 petals joined to form a hood, and the stamens and style projecting beyond the hood. In frost-prone climates, grow as houseplants or in a warm greenhouse. In warm, humid areas, grow epiphytically or in a shaded position among trees and shrubs.
