THU 07 APR 2011 South Holston River Weir Dams, Sullivan Co., TN D. Holt A short walk along the shale hillsides behind Osceola Island around 6 pm yielded a few butterflies and wildflowers. Zebra Swallowtail - 1 West Virginia White - 15 Falcate Orangetip - 5 This site has some Pawpaw, Redbud, Carolina Vetch, a lot of Smooth Rockcress, Golden and Round-leaved Ragworts, tons of toothworts...all potential butterfly hostplants. There are lots of other wildflowers, too. Today I found an Early or Wister's Coralroot Orchid, Corallorhiza wisteriana, the first time I have seen it at this site. Don Holt Johnson City, TN
