Dracopis
''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.
It is one of at least four genera in the flowering plant family Asteraceae whose members are commonly known as coneflowers; the others being ''Echinacea'', ''Rudbeckia'' and ''Ratibida''.
