The jimson-weed, which is a native of Asia, has become quite common in waste places. It is a rank, ill-smelling, nauseating weed, possessing narcotic, poisonous qualities, but its flowers are rather large and showy. The leaves and seeds are made into the drug called "stramonium," which is used as a remedy in neuralgia, spasmodic cough, and other disorders.
As the plant usually grows by roadsides or in the vicinity of dwellings, children are not infrequently poisoned by its fruit and leaves. The poison manifests itself in dryness of the throat, rapid pulse, and delirium; and even death may ensue, preceded by convulsions and coma.
This plant is also called "mad-apple," "apple of Peru," and "Devil's apple."
It has a near relative—D. suaveolens, HBK.,—a large shrub with dark-green leaves and very large, pendulous white flowers. This is common in Californian gardens, and is known popularly as "floriponda," or "angels' trumpets." It sheds a powerful fragrance upon the air at night, which is not noticeable by day.
YARROW. MILFOIL.
Achillea Millefolium, L. Composite Family.
Stems.—A foot or two high. Leaves.—Alternate; sessile; twice-pinnately parted into fine linear, acute, three- to five-cleft lobes; lanceolate in outline; two to four inches long; strong-scented. Flower-heads.—Crowded in a flat cluster; white, sometimes pink; four lines across, including the rays; made up of white disk-flowers and obovate white rays. Hab.—All around the Northern Hemisphere.
The yarrow, which is a common weed in most countries of the Northern Hemisphere, has long been known to botanists and herbalists, and was formerly in high repute for its many virtues. The leaves steeped in hot water are still considered very healing applications to cuts or bruises; and among the Spanish-Californians the fresh plants are used for stanching the blood in recent wounds.
This plant received the name Achillea, because the great hero of the Trojan war was supposed to have been the first to discover its virtues.
