Descriptive notes

Arisaema Triphyllum, commonly referred to as "Jack-in-the-Pulpit", has an inflorescence that is comprised of a long (up to 8 cm), tubular spadix (stalk), covered by a hood.

General distribution and habitat

A. Triphyllum is native to eastern North America, occurring in moist woodlands and thickets from Nova Scotia west to Minnesota, and south to southern Florida and Texas. It grows well in moist areas, including bogs, fens (calcium-rich wetlands), river or stream floodplains, forests, marshes, swamps, and the edges of wetlands.

Campus distribution

A. Triphyllum can be found in relative abundance along the Blue Trail.

Other notes and Fun Facts

Native Americans used the roots of jack-in-the -pulpit for a large variety of medicinal purposes, especially eye and respiratory conditions. Jack-in-the-Pulpit is part of the Araceae familyy, of which several species have been determined to be endothermic (meaning that it they capable of the internal generation of heat). Jack-in-the-Pulpit has not yet been determined to be endothermic, but this is an area for future research. In the late winter/early spring, endothermic plants are able to melt ice and snow and gain access to early season pollinators. This confers a fitness advantage.
