Kalm's hawkweed, Hieracium kalmii

The name of this plant commemorates Pehr Kalm, 1716-1779, who's work I quoted in the wild crabapple item. He was one of the more distinguished of Linnaeus' followers. In 1748-49 he was asked to go to North America to collect seed and specimens for potential agricultural use. On arrival in Philadelphia, he was befriended by Benjamin Franklin and John Bartram (discoverer of Franklinia). He stayed in Raccoon, New Jersey, in the area of the former New Sweden settlement. Oddly, New Jersey is now the only state in which this hawkweed is now endangered. The name and description of this plant were first published by Linnaeus in 1753, from specimens I suspect Kalm provided. Kalm's hawkweed grows in dry, often sandy soil in CT, IA, IL, IN, MA, ME, MI, MN, MO, ND, NJ(E), NY, OH, PA, RI, SD, VT, WI, and WY. Antrim Co MI, 9/8/14.
