A deciduous shrub very similar in general appearance to C. arborescens, differing chiefly in the calyx, which is longer (1⁄3 in. long), more tubular, with broader triangular teeth, and, like the stalk of the flower, clothed with a thick, very dark brown, velvety down. Petals yellow, the wings about as long as the keel. Leaflets seven to eleven, broadly elliptical, indented at the end.
Native of the mountains of Asia Minor; flowers from July to September.
