Remarks

[“Sept. 6. At Brattleboro. . .A. m. – Walked down the railroad about a mile, returning partly by river-bank. . . The prevailing polygonum in B. was a new one to me, P. Pennsylvanicum, but not roughish on the veins, apparently in prime, with the aspects of P. Persicaria, sometimes spreading and stretching four feet along a hillside, but commonly in rather low ground, roadsides.” Journal 9: 62-62. 1856]
