blood-wort; a genus of the monogynia order, belonging to the polyandria class of plants. There is only one species, viz. the canadensis, a native of the northern parts of America, where it grows plentifully in the woods; and in the spring, before the leaves of the trees come out, the surface of the ground is in many places covered with the flowers, which have some resemblance to our wood anemone; but they have short naked pedicels, each supporting one flower at top. Some of these flowers will have 10 or 12 petals, so that they appear to have a double range of leaves, which has occasioned their being termed double flowers; but this is only accidental, the same roots in different years producing different flowers. The plant can bear the open air in this country, but should be placed in a loose soil and sheltered situation, not too much exposed to the sun. It is propagated by the roots; which may be taken up and parted, in September, every other year. The Indians paint themselves yellow with the juice of these plants.
