Apiaceae: Carrot Family – Grassland and disturbed places
Most members of the Apiaceae (carrot) family are characterized by having their flowers arranged in umbels, i.e. with segments radiating from a single point. Formerly, the family was called Umbelliferae. Many have compound umbels. That is when an umbel contains multiple inflorescences, each of which is itself an umbel. Umbels may be rounded, flat-topped or concentrated in head-like structures. Most members of the family have white flowers. Fennel, Lomatiums, most Sancicles and Tauschia all have yellow flowers. This page includes some weeds commonly seen along trails, a few growing up to 3 meters tall.
