Thoreau writes in his journal:
Proserpinaca palustris, spear-leaved proserpinaca, mermaid-weed. (This in Hubbard’s Grove on my way to Conantum.) . . . Tobacco-pipe (Monotropa uniflora) in Spring Swamp Path. I came out of the thick, dark, swampy wood as from night into day. Having forgotten the daylight, I was surprised to see how bright it was . . . Half an hour before sunset I was at Tupelo Cliff, when, looking up from my botanizing (I had been examining the Ranunculus filiformis, the Sium latifolium (? ?), and the obtuse galium on the muddy shore), I saw the seal of evening on the river.
