NIGHTSHADE, a general term for the genus of plants known to botanists as Solanum. The species to which the name of nightshade is commonly given in England is Solanum Dulcamara which is also called bittersweet or woody nightshade (see fig. 1). It is a common plant in damp hedgebanks and thickets, scrambling over underwood and hedges. It has slender slightly woody stems, with alternate lanceolate leaves more or less heart-shaped and auriculate at the base. The flowers are arranged in drooping clusters and resemble those of the potato in shape, although 1 Poets and novelists are apt to command at will the song of this bird, irrespective of season. If the appearance of truth is to be regarded, it is dangerous to introduce a nightingale as singing in England before the 15th of April or after the 15th of June. The "early nightingale" of newspaper paragraphs is generally a thrush.
much smaller. The flower clusters spring from the stems at the side of, or opposite to, the insertion of a leaf. The corolla is rotate, of a lilacblue colour with a green spot at the base of each segment, or sometimes white, and bears the yellow sessile anthers united at their margins so as to form a cone in the centre of the flower. The flowers are succeeded by ovate scarlet berries, in. long, which in large doses appear to be poisonous or, to say the least, dangerous to children, cases of poisoning by them having occurred. Solanum Dulcamara is subject to the same parasitic fungus (Phyto- p h t h o r a infestans) as the potato, and may serve as a medium for communicating spores to the potato if not removed from the hedges of fields where potatoes are grown. The plant derives its names of "bittersweet" and Dulcamara from the fact that its taste is at first bitter and then sweet. It is a native of Europe, North Africa and temperate Asia, and has been introduced into North America. The dried young branches are known in pharmacy under the name dulcamara.

It is a common weed in gardens and waste places, growing about 12 or 18 in. high, and has ovate, entire or sinuate or toothed leaves. Two varieties of the plant, one with red and the other with yellow berries, are sometimes met with, but are comparatively rare. The berries have been known to produce poisonous effects when eaten by children, and owe their properties to the presence of solanine. In Reunion and Mauritius the leaves are eaten like spinach.
Deadly nightshade, dwale or belladonna (Atropa belladonna) is a tall bushy herb of the same natural order (fig. 2). It grows to a height of 4 or 5 ft., having leaves of a dull green colour, with a black shining berry fruit about the size of a cherry, and a large tapering root. The plant is a native of central and south Europe, extending into Asia, and is found locally in England, chiefly on chalk and limestone, from Westmorland and southwards. The entire plant is highly poisonous, and accidents not infrequently occur through children and unwary persons eating the attractive-looking fruit. Its leaves and roots are largely used in medicine, on which account the plant is cultivated, chiefly in south Germany, Switzerland and France (see Belladonna).
The name nightshade is applied to plants of different genera in other countries. American nightshade is Phytolacca decandra (pokeweed, q.v.). The three-leaved nightshade is an American species of Trillium. The Malabar nightshade is Basella, which is widely used as a pot-herb in India. Enchanter's nightshade is Circaea lutetiana, a small, glandular, softly-hairy plant, common in damp woods, with slender, erect or ascending stems, paired ovate leaves with long stalks, and small white flowers in terminal racemes, succeeded by a small fruit covered with hooked bristles; it is a member of the natural order Onagraceae, and is not known to possess any poisonous property; the name seems to have been given to it in the first place in mistake for a species of Mandragora (see Mandrake).
