Arisaema acuminatum
Species of flowering plant
From Wikipedia, the free encyclopedia
Arisaema acuminatum is a species of flowering plant in the arum family Araceae.[2] 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",[3] which describes the shape of the spathe hood. The species is commonly known as the Florida Jack-in-the-pulpit.[4]

Description
Arisaema acuminatum is a herbaceous, perennial, flowering plant growing from a corm. Like other members of the Arisaema triphyllum complex, it has three leaflets per leaf. Its spathe hood is wholly green, "over twice as long as broad", with a long-acuminate tip.[5][6]
Taxonomy
Arisaema acuminatum was first described and named by John Kunkel Small in 1903.[1] Its type specimen was collected in Clearwater, Florida,[7] a city on Florida's west coast. At the time, Small believed that the species was endemic to Florida.[5]
Arisaema acuminatum is a member of the Arisaema triphyllum complex, a group of closely related taxa that also includes Arisaema pusillum, Arisaema quinatum, Arisaema stewardsonii, and Arisaema triphyllum. As of March 2023[update], most authorities consider Arisaema acuminatum to be a synonym for Arisaema triphyllum or A. triphyllum var. acuminatum.[8][9][6][10][11] A few authorities accept Arisaema acuminatum and the other species-level members of the complex.[2][4]
Distribution and habitat
Arisaema acuminatum occurs primarily in Central Florida, hence the common name Florida Jack-in-the-pulpit.[4] 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,[2] but confirmation of that claim is needed.
Conservation
The global conservation status of Arisaema acuminatum is unknown.
