The Henbane (_Hyoscyamus niger_) is an erect plant, with a branching stem from one to two feet high, and the whole is more or less coarse and hairy, with a viscid touch and an unpleasant odour. The flowers are of a dingy yellow colour, and are arranged, with very short stalks, in one-sided, leafy spikes which are curved backwards before the flowers are open. The calyx is at first short, but grows longer, as the fruits ripen, until it is about an inch long. It has prominent veins, and its five lobes are stiff and bristly. The dingy corolla also reaches a length of an inch or more, and is distinctly marked with dark bluish veins. This plant flowers from June to September, and is moderately common in waste places, especially near houses. The other three flowers of this order referred to are all known as Nightshades, and two of them belong to the genus _Solanum_, in which the flowers are arranged in few-flowered terminal or lateral cymes, on short stalks. The corolla has scarcely any tube, and the flowers are easily distinguished by the peculiar arrangement of the five anthers, which are on very short filaments, and are placed close against the style in such a manner as to form a compact cone in the centre of the flower. [Illustration: THE GREAT BINDWEED.] One species--the Black Nightshade (_S. nigrum_)--is rather local in its distribution, but often very abundant where it occurs, appearing as a common weed on cultivated soils. It is an erect, spreading herb, either quite smooth or slightly hairy, growing from six inches to two feet high, with swollen angles on its branching stem. Its leaves are stalked, ovate, more or less wavy, with large angular teeth; and the small, white flowers are on short lateral stalks. The fruit is a small, round, black or scarlet berry. This species may be seen in flower from June almost to the end of the year. [Illustration: THE HENBANE.] The other species--the Woody Nightshade or Bittersweet (_S. Dulcamara_)--is much more common, and may be seen straggling among the hedgerow shrubs almost everywhere. It is a woody climber that supports itself by means of its zig-zag stem, and often reaches a height of six feet or more. The flower seems to be very well known, but is often, if not generally, spoken of as the Deadly Nightshade, which is a much rarer species with quite a different habit and appearance. The leaves are stalked, and usually more or less heart-shaped. Sometimes they are entire, but frequently there is a small lobe on each side of the base. The flowers, though rather small, are very pretty, the conspicuous cone of yellow anthers forming a bright centre to the spreading purple corolla. They bloom from June to September; and towards the end of the season the bright red fruits may be seen in abundance while the flowers are still appearing.
