(Greek name). Umbelliferse. Two weedy biennial plants, widely distributed. C. maculatum, Linn., is the poison hemlock, "by which," as Gray writes, "criminals and philosophers were put to death at Athens." It is a rank, much-branched European herb which has run wild in E. N. Amer., and which has been offered in the trade as a border plant. It is biennial, rank-smelling, and poisonous, and is scarcely worth cult, although the finely cut dark foliage is highly ornamental. It grows from 2-4 ft. high, and has large umbels of small white flowers See Poisonous Plants.
In North America the word hemlock is used for the hemlock spruce, Tsuga.
