UTAH FLORA: APIACEAE (UMBELLIFERAE) Sherel Goodrich' Abstract— Eighty-four taxa in 30 genera of the parsley family, Apiaceae (Umbelliferae) are treated for Utah. Four of the genera with one species each that escape from cultivation are included in the key but not in the text. Keys to genera, species and infraspecific taxa are provided, along with detailed descriptions, distributional data, and pertinent comments. Proposed new taxa are Cymopteriis acaulis (Pursh) Raf var. parvus Goodrich and Lomatiiun scabrum (Coult. & Rose) Mathias var. tripinnatus Goodrich. New combinations include: Cymopteriis acaulis (Pursh) Raf. \ar. fendleri (Gray) Goodrich and var. higginsii (Welsh) Goodrich; Cymopteriis purpureus Wats. var. jonesii (Coult. & Rose) Goodrich and var. rosei (Jones) Goodrich; Cymopteriis terebinthinus (Hook.)
