Appearance
This is an annual herb coated with appressed gray hairs. The stem is very short and the branches extend outward, making the plant squat in stature, sometimes forming a patch on the ground. The alternately arranged leaves are linear. The disc-shaped flower heads are clustered in glomerules 1 or 2 centimeters wide. There are layers of tiny woolly phyllaries around the flower head. It contains usually 4 tubular florets each no more than 1.5 millimeters long. Cypselas from bisexual florets have deciduous white pappi, and those from female florets lack pappi.References:
