Arisaema quinatum - Prester John, Jack-in-the-Pulpit, Preacher John, Southern Jack-in-the-Pulpit, Five-leaved Jack-in-the-Pulpit. In my VERY limited observation there are notable differences between this plant, Arisaema quinatum, and Arisaema triphyllum and most other species of
Arisaema. The most easily noticed difference is that A. quinatum has the
appearance of having 5 leaflets while all the other species (except A. dracontium) clearly have three.
The few individuals I have observed also implies that A. quinatum blooms later, the spathe is smaller relative to the flowering stalk height, and the spadix is thinner than in A. triphyllum. A. quinatum is also found much less frequently than Arisaema triphyllum, as well as having a much narrower distribution in North America, limited to several southeastern states. | Synonym: Arisaema triphyllum ssp. quinatum Update 04/11/2016: I was recently looking at Arisaema, a genus I haven't investigated for identification for quite some time, in Alan S. Weakley's Flora of the Southern and Mid-Atlantic United States and I discovered that Weakley separates as species this plant and others that have been considered subspecies to Arisaema triphyllum in most "official" publications - such as ITIS and Flora of North America. I agree with this separation, and now list it on this site as Arisaema quinatum. Found in: AL, FL, GA, KY, LA, MS, MC, SC, TN, TX Leave comments on Arisaema quinatum at this link.
