Dracopis is a monotypic genus with Dracopis amplexicaulis (clasping coneflower; syn. Rudbeckia amplexicaulis) the sole species. It is native to North America.

It is an annual plant growing to 1 m tall, with simple or branched stems. The leaves are oval, 5–10 cm long and 2–4 cm broad. The flowers are produced in daisy-like inflorescences, with yellow to yellowish-purple florets. It is distinguished from the genus Rudbeckia (in which it used to be treated) by the presence of chaff subtending the ray flowers.
