Rather local; small patch under trees next to large eroding cliff above stream; associated with Erigeron pulchellus, Calystegia spithamea, Desmodium nudiflorum, and Amphicarpaea bracteata. Flowers white.
Only 3 individuals seen, all on single inflorescence of Viburnum acerifolium. They appeared to be actively harvesting nectar from the shallow-cupped flowers (and in the process getting heavily dusted with pollen).
Common, forming patches of basal rosettes on steep eroding slope above stream; plants densely hairy, stems few-flowered.
Panzner Wetland Wildlife Reserve. On bank above yellow pond. Locally abundant.
