A stout, branching biennial, two to over three feet tall, with shining white stems, almost smooth, long, rather narrow, wavy-toothed leaves and enormous flowers, in clusters of two or three at the ends of the branches and opening only in bright sunlight. They are from three to five inches across, with five, broad, light yellow petals and quantities of very long stamens, making a beautiful center. Five of the stamens have broadened filaments, resembling narrow petals, the style is three-cleft, and the capsule is oblong, containing many flat, winged seeds. These plants usually grow in dry stream-beds and are not rare, but through various accidents I have never been able to secure a drawing of either this or the next.
