Epiphytic or terrestrial herbs or subshrubs; stems erect, ascending, or scram- bling, often succulent, bearing adventitious roots. Leaves equal to strongly unequal in a pair, often appearing to be in a rosette, but usually large, elongated and surpassing the stem; usually lanceolate, membranous to fleshy, the apex acuminate, the base cuneate or long decurrent into the petiole. Inflorescences of many flowers, usually congested into axils of the leaves, but rarely exceeding

the length of the petiole.
