Apiaceae: Carrot Family – Lomatium
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, where an umbel contains multiple inflorescences, each of which is an umbel. Umbels may be rounded, flat-topped or concentrated in head-like structures. Most members of the family have white flowers. Notable exceptions are Fennel, Lomatiums, most Sancicles and Tauschia, which have yellow flowers. This page shows Lomatiums, common plants with flat-topped umbels. To identify them, it helps to study the fruits.
