This is often considered the handsomest flower in the West and it would be hard to find anything more beautiful and striking than its magnificent blossoms. The plant has somewhat the effect of a Peony-bush, sometimes, in cultivation, as much as five feet high, with many smooth stems and handsome, smooth, light-green foliage, the leaves cut and lobed, those near the top with a few prickles. The splendid flowers are enormous, from five to nine inches across, with diaphanous, white petals, crinkled like crêpe tissue-paper, and bright golden centers, composed of hundreds of yellow stamens surrounding a greenish-white pistil. The blossoms remain open for several days. The hard, round buds are covered with short, brown hairs. This is the true Matilija Poppy, (pronounced Matíliha,) as it is the kind that grows in the canyon of that name, but the tremendous floods of 1914 drowned most of these beautiful plants in that locality. R. Còulteri is similar, but the buds are smooth and the stems more robust.
Matilija Poppy—Romneya trichocalyx.
There are several kinds of Argemone, natives of the warmer parts of America, with bitter, yellow juice, spiny-toothed leaves and large, conspicuous flowers, the buds erect; sepals two or three, with odd little horns; petals twice as many as the sepals; stamens numerous; style very short, with a radiate stigma; capsule prickly, oblong, opening at the top, containing numerous seeds.

The prickly, bluish-green foliage of this decorative and handsome plant is thistle-like both in form and color. The leafy, branching stems, two or three feet high, are covered with dense, white or yellowish prickles and bear several lovely flowers, over three inches across, with delicately crumpled, white petals and beautiful golden centers, composed of numerous yellow stamens, both stem and leaves having a bluish "bloom." The three prickly green sepals each have a spine-like beak and form a queer-looking, three-horned bud; the pistil has a purplish, cap-shaped stigma, with six lobes, and the prickly ovary becomes a very prickly capsule. This grows in dry places and looks very beautiful and striking when we find its fragile flowers waving in the wind against a background of hot desert sand. It varies a good deal in prickliness and in the form both of plant and flower. When there is only one large flower in bloom, surrounded by a circle of prickly buds, it suggests a fairy princess, guarded by a retinue of fierce warriors. The flowers are often quite broad and flat, and then are sometimes given the prosaic name of Fried-eggs.
There are many kinds of Papaver; with milky juice, leaves lobed or cut, nodding flower buds, showy regular flowers, with two or three sepals and four to six petals. The stigmas are united to form a disk with rays and the fruit is a round or oblong capsule, opening near the top. Both the Latin and common name, Poppy, are ancient. Opium is made from P. somníferum of the Mediterranean.
