The tiny bracts are broadly ovate. The very small cyathia reach up to 3.5 millimeters in diameter and are covered with downy hairs. The nectar glands are elongated. The bluntly lobed fruit is 3.5 millimeters in size and is also covered with very small downy hairs. It stands on a handle about 3 millimeters long.
