Definition: Doryssa is a type of flowering plant that grows in a variety of environments, including wetlands, grasslands, and forests. Its leaves are usually flat or slightly curved, with a single stem that can grow up to 30 feet tall. The flowers are produced in clusters of several hundred to thousands of individual flowers, which bloom in the spring and summer months. Doryssa is known for its long and slender stems, which provide shelter for seeds and insects.
