Be ready. Jack is setting up the pulpit and will be preaching the gospel of the woodland and singing hymns of the water over stones.

I really don’t know Jack still? do you? 

Maybe @spatheandspadix might shed some light on this one.

perhaps y’all have noticed extreme variations in populations of this classic spring plant.

Here is this one:

Narrow spathed, cupped, vibrant color, acuminate  and small. Potentially A. acuminatum???

Ahh yes, a classic to run into while out and about in the forest in May, I still don’t know what subspecies this is and its been in my drafts since like 2016, odd enough I didn’t think this complex would be unresolved this long considering the fact that cernua complex, rudbeckia fulgida complex, and eastern Viola complex(shout outs to Iris Copen and Dr. Harvey Ballard the homies from OU and ODNR/ONAPA) have all had papers since then and so far 3 subspecies have been noted and gone through chromosome analysis and ITS analysis. Non of which are the jack you see above.

Jack in the Pulpit is an incredibly variable and diverse complex/sect. that we see often enough. Morphological variants and subspecies are very noticeable when they occur due to multiple characteristics such as soil specific populations and floral ridges, dwarf like traits, or tapering like you see above. 

Flora of the south eastern USA states this:

“ A genus of about 150-170 species, of Asia, e. North America, e. Africa, and Arabia. Infrageneric taxonomy follows Ohi-Toma et al. (2016). The taxa of the Arisaema triphyllum complex have been variously treated as species, subspecies, varieties, and forms. They are here treated as species with relatively subtle morphological distinctions; they are broadly sympatric, and sometimes occur together in mixed populations with little sign of introgression or hybridization and seem to behave as biological species. Arisaema quinatum (mixed leaved jack) has often been treated as a full species and seems to warrant that status. Arisaema stewardsonii (big ridged hooded bog jack) seems amply distinct in morphology, northern distribution, and boggy habitat. Arisaema triphyllum (common jack) is tetraploid and does not produce fertile seed when crossed with the other (diploid) taxa, including A. pusillum (dwarf alkaline Jack), with which it is broadly sympatric (Treiber 1980).  The size (though diploid), strongly attenuated spathe apex, and geographic integrity seem good reason to accord A. acuminatum (narrow pointed long spathe jack) species status as well.  Species concepts in this treatment largely follow the review by Wyatt & Stoneburner (2022).”

All of this said we still have outliers like this one.

Jack-in-the-pulpits (Arisaema triphyllum) have been out in full force, and I adore them so much.

Elephant cobra lily (Arisaema elephas). It has a vertical spadix appendix exerted over the spathe. These ones are not typical as the flowers are still in the early stage.

Plant of the Day

Monday 19 July 2021

In the shade of the jumble of other plants in my front garden the distinctive flowers of Arisaema candidissimum (white-spathed jack in the pulpit, striped cobra lily) have appeared. The flowers of this tuberous perennial are surprisingly sweetly scented. I like the large trifoliate leaves that appear with or after the flower.

Ohiopyle State Park in Western Pennsylvania’s Laurel Highlands is one of my go-to destinations, in part because it’s close to home, in part because it protects a deep, biologically-diverse mountain river gorge with seemingly endless water features, and in part because it’s one the first wild places I remember visiting with my parents. This morning, I hiked Jonathan Run Trail to the Great Allegheny Passage along the Youghiogheny River, a circuit featuring a half dozen or so significant waterfalls (a few requiring a bit of bushwhacking to reach). Some of the wildflowers currently in bloom in the gorge: wild geranium (Geranium maculatum), golden alexanders (Zizia aurea), downy phlox (Phlox pilosa), dwarf ginseng (Panax trifolius), and Jack-in-the-pulpit (Arisaema triphyllum). The next wave of wildflowers on the way: white clintonia lily (Clintonia umbellulata); and Indian Cucumber (Medeola virginiana).
