}}Calyptocarpus is a genus of flowering plants in the daisy family, Asteraceae.[3][4] The name is derived from the Greek kalypto ("covered or hidden") and karpos ("fruit").[5] Species are distributed in the southern United States and Latin America.[5] These are perennial herbs with decumbent to prostrate stems up to 30 centimeters long. The oppositely arranged leaves have blades of various shapes with toothed edges. Flower heads are solitary in the leaf axils. Each has 3 to 8 light yellow ray florets and several yellow disc florets. The fruit is a flat cypsela with a pappus of 2 or more awns.[5] There are 2[5][6] to 6[7] species accepted in the genus.
