About

Arisaema quinatum 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 quinatum means "divided into five lobes", a reference to its characteristic leaves. It is commonly known as the southern Jack-in-the-pulpit (or southern Jack) but some refer to it as Preacher John.

Where it grows

Arisaema quinatum is narrowly endemic to the southeastern United States, ranging from North Carolina to east Texas. It is known (but rare) as far north as West Virginia. A disjunct population occurs in the central portion of the Florida Panhandle, in Walton, Liberty, Leon, and Jefferson counties, where the species is commonly known as Prester John.
