Little cutie on Nance's Creek.
ID is iNat's suggestion.
Photographed in a roadside calcareous prairie remnant. This is the only known population in Georgia.
Upland depression, possibly a ditch but might be a natural depression
With David Whetstone and Bill Garland. Digitized slides.
Shady roadside, sizeable colony (at least 30 ft wide)
Petals 7–8mm long
Largest leaflets up to 9cm, but most 5–7cm
A few rather large petioles measured about 20–22cm, but most were under 15cm long
This species has been something of a white whale for me. I'm happy to have finally found it!
June 2024 update: I returned to this patch to see if there were any fruits, but it seems the city mowed it.
Riparian woods. With Adam Dasinger & Eric Soehren. Adam discovered this county record and showed us the site. He is the one standing next to the tree in the photos.

Found on a granite road cut very near verified population of Phemeranthus parviflorus

Significantly outside previously reported range. Multiple plants including a couple of small trees in two separate groups. Found along lower slopes of wooded valley near creek. In association with mountain-laurel, Piedmont azalea, common sweetleaf, sourwood, chalkbark maple, and common witch-hazel.
This plant appears to be an undocumented wild hybrid of Alabama cherry and black cherry, Prunus alabamensis × serotina.
At present, iNat ranks Alabama cherry as a variety of black cherry, P. serotina var. alabamensis. This contradicts regional authorities, such as Weakley's Flora of the Southeastern United States, which regard it as species. Species rank is usually recognized for much less than what separates these taxa. Unfortunately, POWO has yet to be brought up to date with regional authorities, and iNat's toxonomy is based on POWO.
Comparison images included hybrid leaf alongside leaves from parent species.
What cannot be appreciated from the pictures is the leaf texture. P. serotina leaves are flat and smooth, while P. alabamensis leaves are rough and bumpy due to the hairs and prominent veins. The hybrid is mostly smooth like P. serotina, but the veins are prominent, so it is also bumpy like P. alabamensis.
Pubescence on underside of leaf is intermediate the parent species. P. alabamensis is pubescent over the entire surface, though moreso along the midrib and primary veins. P. serotina is almost entirely glabrous, except for lines of hairs flanking the base of the midrib. The hybrid is mostly pubescent, but patches between the primary veins are almost glabrous.
The hairs of all species are more visible late in the season when they turn a rusty orange color.
In winter condition, P. alabamensis can be distinguished by the presence of a dense mat of simple trichomes along the twigs below the terminal buds, best confirmed with magnification. These trichomes are entirely absent on P. serotina. The hybrid has the expected intermediate trait of scattered but not densely matted trichomes.
Found in Bellfort CenterPoint ROW Prairie. (I was very happy to be spending Pride out on the prairie for the NA Prairie Conference. A little bit of botanical humor here (common name "gay feather") This photo was taken for joy so unfortunately its the only one I have of this specimen)
