On our chalk-downs, and on banks in gravelly soils, from June to September the pale yellow flowers of the Rock-rose are abundant. In spite of its plentifulness, however, it is not among those flowers that are generally known, except to the botanist. The rest of the world probably includes it among the buttercups, with which it has no relationship. The plant is shrubby, with a creeping rootstock; its branches trail on the ground among grass and low herbage. It is therefore by no means a conspicuous plant, though it occurs in considerable masses, and is perennial. The leaves are small, oblong, with an even margin; the upper surface hairy, the lower downy. They are arranged in pairs on the stem, and provided with stipules. The flower-bud is protected by only three sepals, but there are two others reduced to the size and shape of stipules; and so their number really corresponds with the five somewhat flabby petals, which have the softness of the poppy rather than the stiffness of the buttercup. The stamens that surround the pistil are a multitude; they are also irritable, and on being touched fall back from the pistil. The plant is common throughout the country, except in Cornwall and West Scotland, in which districts it is rare. The name is Greek, and signifies sunflower.
