原生地・分布（英語）:

説明（英語）: Genus of about 130 species of annuals and perennials, some monocarpic, or rarely subshrubs, often found in rain-forest, sometimes as epiphytes, and on damp banks and rocks or in grassland. They occur from tropical to southern Africa, in Madagascar, and in China, with 4 species from S.E. Asia. Linear to rounded, hairy, often mid-green, veined, wrinkled leaves are borne singly or in opposite pairs on erect, fleshy stems, or in stemless rosettes. Cymes of tubular, often 2-lipped flowers, with 5 spreading lobes, are axillary or borne from the leaf rosettes. In frost-prone areas, grow in a temperate or warm greenhouse. Use in a humid, shady border in warmer areas.

耐寒性（英語）: Frost tender.
