Description
D. stramonium is a foul-smelling, erect annual, freely-branching herb that forms a bush up to 2 to 5 feet (60–150 cm) tall.
The root is long, thick, fibrous and white. The stem is stout, erect, leafy, smooth, and pale yellow-green. The stem forks off repeatedly into branches, and at each fork forms a leaf and a single, erect flower.
The leaves are approximately 3 to 8 inches (8–20 cm) long, smooth, toothed, soft, irregularly undulate. The upper surface of the leaves is a darker green, and the bottom is a light green. The leaves have a bitter and nauseating taste, which is imparted to extracts of the herb, and remains even after the leaves have been dried.
D. stramonium generally flowers throughout the summer. The fragrant flowers are trumpet-shaped, white to creamy or violet, and 21⁄2 to 31⁄2 inches (6–9 cm) long, and grow on short stems from either the axils of the leaves or the places where the branches fork. The calyx is long and tubular, swollen at the bottom, and sharply angled, surmounted by five sharp teeth. The corolla, which is folded and only partially open, is white, funnel-shaped, and has six prominent ribs. The flowers open at night, emitting a pleasant fragrance and providing food for nocturnal moths.
The egg-shaped seed capsule is walnut-sized and either covered with spines or bald. At maturity it splits into four chambers, each with dozens of small black seeds.

Famous quotes containing the word description:
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
