An erect, glabrous or minutely pubescent, branched annual. The stems are striate; the leaves are rather distant, 2-3-pinnately divided, the segments linear. The flowers occur in terminal or seemingly-lateral pedunculate, compound umbels, white and small; the fruits are ovoid, muricate, aromatic cremocarps, greyish brown; the mericarps, which are the components of the fruit, are compressed, with distinct ridges and tubercular surface, 1-seeded.
