The leaves are narrowly lance-shaped, rapidly tapered to both ends, the margins neither toothed nor lobed. Yellow flowers grow in clusters terminally and from upper leaf axils; with age these clusters elongate greatly as fruits develop. The fruits are linear, and grow from short ascending stalks. | |
