The Celandine is a loose branching herb, sprawled commonly along roadsides and waste places, in fields, and about old buildings. It has been naturalized from Europe, and is often confused with the Black Mustard by those who are not familiar with the flowers. The light green stalk has a whitish bloom, and grows from one to two feet high. It is sparingly hairy, weak and brittle, and is filled with a copious orange-coloured, acrid juice that stains everything it touches, and which is said to be poisonous. Small boys paint warts with it in the hope of removing them, and for the same effect, their parents have used the irritant juice on their corns. The pretty little odourless flowers are half an inch or more broad, and are borne in small, loose clusters on slender stems. The four slightly curved, spreading, oval petals are pure yellow and lustreless. The prominent, slender, green pistil is surrounded with numerous pretty yellow stamens, with yellow anthers. The buds are nodding, and the two yellowish sepals fall as the flower opens. The thin, loosely textured, yellowish green leaf is not unattractive. It is compound, and deeply cleft into five or more, generally oval leaflets, which are arranged alternately, and have their margins irregularly scalloped. The under surface has a whitish bloom, and is strongly ribbed and veined, the veination showing through on the upper side. They set gracefully on short, weak, hairy stems. The seed pod is long and slender, and often measures two inches in length. It is smooth and two-parted, and splits upward from the bottom when matured. The Celandine blossoms from April to September throughout the Eastern States. The name is derived from the Greek Chelidon, a swallow, and was used by Dioscorides, because, it is said, the flowers appeared in the spring when the swallows arrived, and perished in the fall when these birds departed. For this reason it is also called Swallow-wort.
