Thoreau writes in his journal:
The cotton-grass at Beck Stove’s. Is it different from the early one? High blueberries begin. The oval-leaved drosera in bloom . . . At Lee’s Cliff, under the slippery elm, Parietaria Pennsylvanica, American pellitory, in flower, and near by Anychia dichotoma, forked chickweed (Queria [sic]) also in flower.
