Remarks

[“Aug. 11. . .P. M. Walk to Conantum with Mr. Bradford. . . A new sunflower at Wheeler’s Bank, this side Corner Spring,which I will call the tall rough sunflower; opened say August 1st (?). (I saw it out the 7th.) It does not correspond exactly to any described. Stem three to six feet high, branched at top, purple with a bloom, roughish, especially the peduncles. Leaves opposite, except a few small ones amid the branches, thick, ovate or ovate-lancoelate, taper-pointed, three-nerved, obscurely and remotely toothed, rough above, smooth and whitish below, abruptly contracted into margined petioles. Scales of the involucre lanceolate, taper-pointed, subequal, exceeding the disk, ciliate; rays eight or nine, one and a half or more inches long, chaff black. Edge of meadow.” Journal 8: 461-462. 1856]
