“ Water Dropwort, Oenanthe crocata (nat. ord. Umbelliferae) , is a tall herbaceous plant growing in marshes and ditches. The stem, which springs from a cluster of thickened roots, is stout, branched, hollow and 2 to 5 ft. high; the leaves are large and pinnately divided, and the flowers are borne in a compound umbel, the long rays bearing dense partial umbels of small white flowers. The plant, which is very poisonous, is often mistaken for celery. ”
