About

Arisaema acuminatum is a species of flowering plant in the arum family Araceae. It is a member of the Arisaema triphyllum complex, a group of closely related taxa in eastern North America. The specific name acuminatum means "with a long, narrow and pointed tip", which describes the shape of the spathe hood. The species is commonly known as the Florida Jack-in-the-pulpit.

Where it grows

Arisaema acuminatum occurs primarily in Central Florida, hence the common name Florida Jack-in-the-pulpit. Its range extends southward into the Florida peninsula and northward along the coast of eastern Georgia. It is claimed to occur in east Texas as well, but confirmation of that claim is needed.
