Thoreau writes in his journal:
Cnicus pumilus, pasture thistle. How many insects a single one attracts! While you sit by it, bee after bee will visit it, and busy himself probing for honey and loading himself with pollen, regardless of your overshadowing presence. He sees its purple flower from afar, and that use there is in its color.
Oxalis stricta, upright wood-sorrel, the little yellow ternate-leaved flower in pastures and corn-fields.
Sagittaria sagittif olia, or arrowhead. It has very little root that I can find to eat.
Campanula crinoides, var. 2nd, slender bellflower, vine-like like a galium, by brook-side in Depot Field.
Impatiens, noli-me-tangere, or touch-me-not, with its dangling yellow pitchers or horns of plenty, which I have seen for a month by damp causeway thickets, but the whole plant was so tender and drooped so soon I could not get it home.
May I love and revere myself above all the gods that men have ever invented. May I never let the vestal fire go out in my recesses.
