Arisaema triphyllum
species of plant
Arisaema triphyllum, the Jack-in-the-pulpit, is a species of flowering plant in the arum family Araceae. It is a member of the Arisaema triphyllum complex, a group of four or five closely related taxa in eastern North America. The specific name triphyllum means "three-leaved", a characteristic feature of the species, which is also referred to as Indian turnip, bog onion, and brown dragon.
Used without qualification, the name Arisaema triphyllum is ambiguous. For clarity, the qualified name Arisaema triphyllum sensu stricto (abbreviated s.s.) refers to the species while Arisaema triphyllum sensu lato refers to the species complex. The latter includes the species (Arisaema triphyllum) among its members.
Arisaema triphyllum sensu lato is wide-ranging across eastern North America, from Nova Scotia to Manitoba in eastern Canada, and from Texas to Florida in the southern United States. It is common throughout most of its range.
Description
The Arisaema triphyllum complex includes four closely related species: Arisaema pusillum, Arisaema stewardsonii, Arisaema quinatum, and Arisaema triphyllum sensu stricto. A fifth species (Arisaema acuminatum) is sometimes included but its validity is controversial.
This brief starts where responsible research should: with the source description of “Arisaema triphyllum” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q2716758. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
