Description

Species of ''Stylocline'' are generally small plants, and certain ones 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.
