From Flora of Indiana (1940) by Charles C. Deam
This plant is poisonous and each year in this state there are reports of the death of stock due to eating it. A man in Wells County, mistaking the tuberous roots for sweet anise, ate them and died. Frequent throughout the state in low ground about lakes and ponds, in low woods, and in and along ditches.
Welsh et al. 1993, Martin and Hutchins 1980
Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Stout perennial from tuberous base, stems to 2 m tall. Leaves: Alternate, basal and cauline, once to thrice pinnately compound with dentate leaflets, 4-7 opposite pairs of leaflets linear-lanceolate to lanceolate, 3-10 cm long, margins serrate to incised. Flowers: Compound umbels on peduncles 5-15 cm long, bracts of the involucre lacking or with few linear bracts to 1 cm long, 15-26 rays, these 1.5-4 cm long, pedicels 3-10 mm long; calyx teeth about 0.5 mm long, pale green with whitish margins, petals white, stamens white, with depressed-conic stylopodium. Fruits: Ovoid to orbicular, 2-4 mm long, corky, green with prominent ribs. Ecology: Found along streams and rivers, along margins of ponds and lakes, and in wet meadows and marshes from 4,500-8,000 ft (1372-2438 m); flowers June-September. Notes: This plant is highly poisonous, think Socrates. Pay attention to the purple spots near the base of the stem where it meets the ground, this is good for distinguishing this species and Conium maculatum, the invasive hemlock. Ethnobotany: There are some uses for this plant, albeit a poisonous plant. Used as insecticide, for sterility if ingested, ceremonially, to help with broken bones and bruises, and as a poison for hunting. Etymology: Cicuta is the Latin name for hemlock, while maculata means spotted. Synonyms: None Editor: SBuckley, 2010
