Tonestus graniticus, common name Lone Mountain serpentweed, is a rare endemic plant species known only from the east side of Lone Mountain in Esmeralda County, Nevada, about 20 km (12.5 miles) west of Tonopah.[2] It grows there in the crevices of granitic outcrops.[3]
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.[4][5][6]
