Conandron ramondioides is a species of flowering plant in the family Gesneriaceae. It is the sole species in genus Conandron.[1] It is native to eastern Asia, where it is found in southeastern China, Japan, Taiwan, and Vietnam.[2][3] Its natural habitat is on damp rock faces, in forests and along streamsides.[4][3] It is a common species in Japan.[5]

It is a perennial, growing to ~30 cm tall. It has large basal leaves. Flowers are purple and produced in the summer.[3][5]

Its Japanese name (岩煙草) is "rock tobacco", in reference to the resemblance of its leaves to tobacco, and its preference to grow on exposed rock.[6]
