The inflorescence is a zigzagging series of branches bearing occasional flowers on thin pedicels. There is a single tiny bract at the base of each pedicel. The flower is a few millimeters long. It has five triangular sepals and five corolla lobes, three lobes on the upper lip and two on the lower. The corolla is white to pale purple or pink with a thin red band and yellow spot at the base of each lobe.
Nemacladus ramosissimus is a species of flowering plant in the bellflower family known by the common name smallflower threadplant. It is native to the mountains and deserts of the southern half of California and adjacent parts of Baja California.
