A small, much-branched perennial herb with tiny star-shaped hairs.

Leaves alternate, on long stems, ovate to oblong with crenate (scalloped) margins. Leaf stems have at their bases a small, spinelike projection, which is quite soft until the plant matures and dries out. Fruit a flattened ring that splits into 5 wedge-shaped sections (mericarps) each with a pair of short beaks toward the tip.
