Orthocarpus, or owl's-clover,[1] is a genus of flowering plants in the family Orobanchaceae (broomrapes). They are native to North America. A number of species formerly included in Orthocarpus have been transferred to the genus Castilleja, which includes the plants commonly known as Indian paintbrush. Plants of the genus are generally less than 30 centimetres (1 ft) in height.[2]

Some animal species such as the Edith's checkerspot butterfly use these plants as hosts during ovipositing.[3]
