Arisaema pusillum

Arisaema pusillum 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 pusillum, which means "very small, slender", describes the overall size of the plant relative to that of the more common Arisaema triphyllum. It is commonly known as the small Jack-in-the-pulpit (or small Jack). It is sometimes referred to as the swamp Jack, not to be confused with Arisaema stewardsonii, which is also known by that name.
