dogs-bane

He who traverses the woodland paths, at this season, will have occasion to remember the small drooping bell-like flowers and slender red stem of the dogs-bane, and the coarser stem and berry of the poke, which are both common in remoter and wilder scenes; and if "the sun casts such a reflecting heat from the sweet fern," as makes him faint, when he is climbing the bare hills, as they complained who first penetrated into these parts, the cool fragrance of the swamp pink restores him again, when traversing the valleys between.
