Tonestus graniticus is a perennial herb growing close to the ground and forming mats. Leaves are ovate to spatulate, irregularly toothed, up to 4 cm (1.6 inches) long. Flower heads are born in racemose or corymbiform arrays. There are no ray flowers, but up to 23 yellow disc flowers.
Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are born on longer pedicels than the inner, bringing all flowers up to a common level. A cyme has a flattish top superficially resembling an umbel, and may have a branching structure similar to a panicle. Flowers in a corymb structure can either be parallel, or alternate, and form in either a convex, or flat form.
