СКАЧАТЬ in appearance that it is difficult for the amateur to realize that they are nearly related. In fact they have no very distinctive characteristics. They are all herbs, except Clematis, which is shrubby, and all have bitter juice, which is never milky or colored, numerous stamens and usually several pistils, which are superior and one-celled, bearing a single style, and all the parts of the flower are separate from each other and inserted on the receptacle. The flowers are often of eccentric forms, with spurs or hoods; sometimes they dispense with petals altogether and instead have colored sepals which resemble petals. The leaves are of all sorts and shapes, usually more or less lobed and cut, but have no stipules and often their bases clasp the stem. The fruit is an akene, pod, or berry. Many of our most beautiful and popular garden flowers are included in this family, which is large and distributed throughout the world, but not abundant in the tropics.

      There are numerous kinds of Ranunculus, mostly perennials, with fibrous roots, growing in temperate and cold regions. Ours have yellow or white flowers, with three to five sepals and from three to fifteen petals, each of the petals with a nectar-gland at its base; the numerous pistils developing into a roundish or oblong head of akenes. The leaves are variously cut and lobed, the stem leaves alternate. Some sorts grow in the water and some have creeping stems. Some kinds of Ranunculus are liable to be confused with some sorts of Cinquefoils, but the calyx of a Buttercup has no bractlets, as has that of a Cinquefoil. The Latin name means "little frog," as these plants like marshes.

      The commonest kind are attractive, often coloring the fields for miles with bright gold, but the flowers are not so pretty as some common eastern kinds. The stems are branching and more or less hairy, nine inches to a foot and a half tall, with dark-green leaves, smooth, hairy or velvety, and velvety, hairy buds. The flowers are about an inch across, with from nine to sixteen, bright-yellow, shiny petals and pale-green sepals, turned closely back. The akenes have hooked beaks. This runs into many scarcely distinguishable varieties.

      

      Common Western Buttercup – Ranunculus Californicus.

      Few flowers are more beautiful and interesting in color and construction than Larkspurs. We are all familiar with their tall spires of oddly-shaped blossoms, growing in gardens, and we find them even more charming in their natural surroundings, glowing like sapphires on desert sands, or adorning mountain woods with patches of vivid color. There are many kinds; ours are perennials, with palmately-divided leaves and usually blue or white flowers, very irregular in form, with five sepals, resembling petals, the upper one prolonged into a spur at the back, and usually four petals, two of which are small and inside the calyx-spur, the larger two partly covering the pistils and the numerous stamens. The pistils, from one to five, become many-seeded pods. Some Larkspurs are poisonous to cattle. The Latin name is from a fancied resemblance of the flower to the dolphin of decorative art. Spanish Californians call it Espuela del caballero, Cavalier's spur.

      Though sometimes rather small, this is extremely pretty. In the Grand Canyon, on the plateau, it is about a foot tall, with rather leathery, brownish-green leaves, mostly from the root, and from five to twelve flowers in a cluster. They measure nearly an inch across and are brilliant and iridescent in coloring, as except for two small whitish petals, they are the deepest, brightest blue, exquisitely tinted with violet, with brown anthers. At Tucson, among the rocks above the Desert Laboratory, it grows to over a foot in height, with a cluster over six inches long and light dull-green leaves, slightly stiff and thick, with long leaf-stalks, the lobes tipped with a bristle, forming a handsome clump. This grows on dry plains and rocky hillsides, up to seven thousand feet. The picture is from a Grand Canyon plant.

      If the flowers were a little less pale in color this would be a gorgeous plant, for it sometimes grows nearly four feet high. The branching stem springs from a cluster of thick, tapering roots, each branch terminating in a long, crowded cluster of twenty or thirty flowers, opalescent in tint, either white, with a bluish or greenish spot on the tip of each sepal, or very pale pink, with a purplish or bluish spot. The dull, yellowish-green leaves are rather thickish and downy, the pods erect. This grows in dryish places, at moderate altitudes, and freely around Yosemite.

      A splendid flower when at its best, from six inches to a foot and a half tall, with a smooth stem, reddish below, and smooth, bright-green leaves, pale on the under side, round in general outline, the lower ones with long, reddish leaf-stalks sheathing the stem, the roots thick but not tuberous. The beautiful flowers are sometimes an inch and a half across, on long, rather spreading pedicels, few or many, in a long loose cluster, the buds slightly downy. The general effect of the flowers is deep bright-blue, but when we examine them more closely we find that the slightly woolly spurs are purplish, the blue sepals have on the back protuberances, which are pinkish on the front and greenish on the back, the two, small, upper petals are white, delicately striped with purple, and the lower ones, which are fuzzy with tufts of white down and two-cleft, are deep pinkish-purple; sometimes the whole flower is much paler in color. The anthers are large and green at first, becoming small and yellow, their threadlike filaments curling. This grows on dry hills. D. Párryi, of California, is about two feet tall, similar in coloring, but even handsomer, with a cluster nearly a foot long, closely crowded with beautiful flowers, each an inch and a half across. The lower leaves are slashed nearly to the center, into seven divisions, each with three, long, narrow lobes.
