The small, radially symmetrical, 5-petaled flowers are borne in umbels (umbrella-shaped clusters). These umbels are usually compound, with each branch of the primary umbel supporting the secondary umbels. The alternate leaves are mostly pinnately compound. The leaf stalk forms a sheath around the hollow stem.
Carrots, celery and parsnips are members of the family, as are parsley, dill, coriander, caraway and anise. Some species are very poisonous, Poison hemlock having been the drink given to Socrates.
