Remarks

[“July 6 . . . At Saw Mill Brook, Circaea alpina, enchanter’s-nightshade, moist shady places, with thin tender leaves somewhat like the touch-me-not’s” Journal 4: 196. 1852. “July 16. . .P.M. – Via railroad and pond to Saw Mill Brook. . .The large (?) circaea (it is the lutetiana, though the flowers are white), apparently two or three days.” Journal 6: 396-7. 1854. "The Circaea at Sawmill Brook is the same with that at [Viola] Muhlenbergii Br[ook]. It differs from Gray’s C.[ircaea] Lutetiana in the stem not being mostly pubescent (but conspic.[uously] smpooth) -- there being some bracts, not to say stipules the latter sometimes very large -- the hair of the fruit not being bristly (Yes it is rather so Aug. 26th). From his Alpina in not being low & weak (one is 37+ inches high some are low and not branched) -- the leaves not shining. Now coarsely toothed, but remotely & slightly. It differs from Bigelow's [Circaea] Lutetiana in leaves not being pubescent (except under a glass) -- petals not being reddish white -- From B[igelow]’s [Circaea] Alpina in not being a particularly small & humble plant, & the leaves not being very distinctly heart shaped. Call it Circaea simply V[ide] Aug 13th 56." unpublished passage for July 24, 1856]]
