In mesic to wet-mesic sand savanna, uncommon among a larger population of Viola sagittata and scattered Viola missouriensis
These plants are very similar to V. sagittata but have unusually ovate leaves without lobes at the base, and the leaves have unusually sparse pubescence with hairs restricted to the upper surface and margins.
I initially assumed these were a hybrid between V. sagittata and V. missouriensis, or possibly another related species like V. nephrophylla or V. cucullata. However, these plants have narrowly but distinctly winged petioles, which is not characteristic of any of the violet species I've mentioned. These plants ultimately key out well to V. emarginata "Lower Midwest variant"
Coincidentally, V. emarginata has been suggested to be a hybrid between V. sagittata and V. affinis by some authorities in the past. V. missouriensis is closely related to V. affinis and the two species may intergrade in this part of the Midwest. V. sagittata in this part of the Midwest shows evidence of past introgression with V. fimbriatula, which typically has winged petioles. Is it possible that the plants in this observation really are hybrids expressing a phenotype derived from V. fimbriatula?
the form closest to the "var. pseudostoneana" form I could find here; about 20% of the plants here are this deeply dissected.
Nothing in bloom at home yet. I had to go see something.
Mohican State Park
-leaf cells are small (mostly ~18-35 microns); leaves nearly round, strongly decurrent, 7-12 cells wide; sinus less than half-way; lobes fairly sharp, mostly connivent and 3-4 cells wide. Growing on moist cliff face among other bryophytes.
Newcomb’s Group No. 523
regular wildflower with 5 petals and basal leaves only; leaves long-stalked, roundly heart-shaped with blunt teeth and 5 to 9 shallow lobes, often with dark veins; flowers 0.25 inch long, green or purplish with protruding stamens; blooms in late spring and summer; plant is 1 to 3 feet high
Growing in a flower bed but I don't think it was planted
Endemic to the Appalachians and one of the only aquatic lichens, this species is uncommon and is indicative of high water quality. It looks like it belongs in a tidal pool. A Pennsylvania 'Watchlist' species.
I’m basing this Id primarily on the leaf shape but totally open to other ideas…..Provenance is somewhat uncertain - while it is not something I planted, it came up in an area where I HAVE planted some iris virginica so peehaps it was transported in with that from the nursery.
Hairs on lateral petals are not knobbed. Sepals are lanceolate and not hairy. Leaves are longer than wide, and basal teeth are larger than apical teeth. Formerly considered a variety of coast violet (V. brittoniana)
Along the hiking trail, about 5 inches wide, no more than 3 inches tall
Some Endangered Violet they have, said the person who works there
syn. Viola subsinuata Greene, V. palmata var. angelliae (Pollard) W. Stone, growing beneath large old white oaks on a ridge near hemlocks, unique lateral petal pubescence, stems and other flower parts pubescent (see also https://www.inaturalist.org/observations/199643111 for 870515046b). No. 870515046a.

Guessing Spotted since I found an adult ten feet away from this pool.
Edit (Nov 26 2023) Was researching Tiger Salamanders and went down a rabbit hole of IDing larvae. I am now wondering if this isn't a Tiger Salamander larvae. According to an ID extension put out by Purdue University, pointed toes is a unique feature of Tiger Salamanders, which seems to be the case for this larvae.
