Many adjacent plants appeared to have been sprayed with herbicide. Most of upper ravine trail system appeared to be affected. Much Brachyelytrum poisoned or killed. As well as Thalictrum, Cryptotaenia, Trillium, Endodeca, Taenidia, Thaspium spp, Allium burdickii, Hepatica, Packera, Helianthus, Geranium, Arnoglossum, Silphium, Symphyotrichum, Carex jamesii, Carex albursina, Carex platyphylla, other Carex spp, and many, many others. Seriously misguided.
Trail thru rare plant community seems a strange place for herbicide. YO RB w comm.

Outer edge of the marsh zone in a poor fen complex

I don't think this is the pure-strain American variety, but it's the closest to it that I've ever been able to document.

Many of the leaves have terminal lobes that are comparatively deltate. The leaves are very pubescent. And a significant proportion of the stipules ate broadened at the tips. But the petiolar glands are squat and rimmed, and the leaves could be more "trilobed". I feel that the overall balance of characteristics puts this closer to the American variety.

Another small patch wild in the bot gardens! loads of wild seedlings too, seed pods on adults, have removed pods and destroyed, and shown the gardeners who have done a good job of getting rid of the last lot, will check again in a couple of months

Interior Plateau/Appalachian phenotype, which retains its leaves as scape is produced. Cubelium (Hybanthus) concolor a common associate here, with lots of exposed limestone. Plants and smaller colonies scattered over.a fairly large area, at the top of the ridge and on upper slopes.
