Pretty plants, from eight to fourteen inches tall, with branching, hairy stems and light green, soft, downy leaves. The flowers are less than half an inch long, with pale yellow corollas, and are at first erect, but gradually droop until they hang gracefully on their very slender pedicels. They become dry and papery as they wither, but keep their form, and when the wind shakes their slender stems they respond with a faint rustling sound. This grows in dry places and is common in the South. In Arizona it grows only in protected canyons.
There are several kinds of Hydrophyllum, perennial or biennial herbs, with fleshy running rootstocks and large, more or less divided leaves, mostly alternate. The corolla is bell-shaped, with a honey-gland at the base of each of the petals, which are rolled up in the bud. The filaments are hairy, the style two-cleft above, both stamens and style are generally long and protruding, and the ovary is one-celled and hairy, containing from one to four seeds.
