Etymology

"The epithet is Latin for button-like. Like several other annual composites, this is a prostrate plant in which the stems and leaves lie on or just below the soil surface (and are the same colour as the soil), while the inflorescences are held on shortly ascending terminal branches near the soil surface and appear from above as a collection of buttons."
