Nightshade
Solànum Douglásii
White
Spring, summer
Southwest

A branching plant, about two feet high and across, with roughish stems and thin, smooth or slightly hairy, dark green leaves, toothless, or the margins more or less coarsely toothed. The flowers are white, tinged with lilac, with a purplish ring surrounding the yellow cone formed by the anthers. In southern California the flowers are nearly half an inch across, but smaller elsewhere. The berries are black. This is common throughout California near the coast. S. nìgrum, the common Nightshade, is a weed in almost all countries, common in waste places and in cultivated soil, and has small white flowers and black berries, about as large as peas and said to be poisonous.

Purple Nightshade—Solanum Xanti.

There are many kinds of Nicotiana, or Tobacco, chiefly American; acrid, narcotic herbs or shrubs, usually sticky-hairy; leaves large, toothless; corolla funnel-form or salver-form, with a long tube and spreading border, plaited in the bud; stamens with threadlike filaments and broad anthers, not protruding; capsule smooth, containing numerous small seeds. The name is in honor of Nicot, diplomat and author of the first French dictionary, who sent some of these plants to Catherine de' Medici from Portugal in 1560.

Nicotiàna glaùca

Spring
Southwest

A very slender, loosely-branching evergreen shrub, from six to fifteen feet high, with graceful, swaying branches and smooth, thick leaves, with a "bloom," the lower leaves eight inches long. The flowers are nearly two inches long, greenish at first and then becoming a rather pretty shade of warm dull-yellow, and hang in graceful clusters from the ends of the branches. The calyx is unequally five-toothed, the tube of the corolla downy on the outside; the anthers whitish; the ovary on a yellowish disk, with a long style and two-lobed stigma, and the capsule oblong, half an inch long. This was introduced into California from South America about fifty years ago and is now common in waste places and cultivated valleys.

There are many kinds of Lycium, shrubs or woody vines, named for the country Lycia.

Desert Matrimony
Lycium Còoperi

Spring
Southwest

An odd-looking desert shrub, everything about it so closely crowded as to give a queer bunchy and clumsy effect. It is three or four feet high, with thick, dark gray, gnarled, woody branches, crowded with tufts of small, dull, light green leaves, which are thickish, stiffish, obscurely downy and toothless, and mingled with close little bunches of flowers. The flowers are about half an inch long, with a large, yellowish, hairy calyx, with five lobes, a white corolla, which is slightly hairy outside, with five lobes and a narrow, greenish tube, and pale yellow anthers, not protruding. They are rather pretty near by, but the appearance of the whole shrub is too pale to be effective. The familiar Matrimony Vine of old-fashioned gardens belongs to this genus.
