Succulent scandent shrubs, epiphytic or upon rocks, the primary stem joints terete or weakly ancipitous, the secondary stem joints very narrowly oblong- lanceolate, rounded at the tip, cuneately decurrent into a very short subpetiolar base, 3-5 dm. long, 3-5 cm. broad, very narrowly and closely cuneate-serrate, thick and callose-marginate in dessication, the areoles 1.0-2.5 cm. distant, naked or indefinitely papillate beneath the minute imbricate scales, borne superficially upon the upper margin of the narrow serrations. Flowers ephemeral, rather small, tubular, pink tipped with lavender, the perianth tube about 1.5 cm. long, about 2 mm. in diameter at the base, scarcely dilated toward the orifice, the perianth segments about 10, about 1 cm. long, erect or essentially so; ovary about 3 mm. long, minutely tuberculate-bracteate. Berry not seen.
