Stylocline (neststraw) is a small genus of North American plants in the inula tribe within the daisy family. These are generally small plants and certain species are difficult to distinguish from each other because identifying characteristics are too small to see with the naked eye. They are annuals with woolly, hairy, or spiderwebby textures. Thin stems end in heads of disc flowers or tubular pistillate flowers. The fruits are smooth and shiny and encapsulated within the disc heads. Neststraw is native to the southwestern United States and northern Mexico.
