The fruit is composed of two dry, ridged carpels, often traversed by canals filled with pungent oils, and adherent to a central stalk,. They have jointed stems, the lengths between the nodes being usually hollow. The alternate leaves are occassionaly undivided, but mostly much dissected, the leaf stalk dilated at the base and clasping the stem. Research Umbelliferae
