Stem not "velue-hérisée". Lower has fallen. & the remaining might fit the species or the variety. 10-13-38 Bidens frondosa L. G 840; Bv B III 497 F2. With above. Fl with 10-16-38 from Kilwood. Plants to 2 ft & very much branched, and outer bracts frequently 9, but otherwise seen the same. Achene 2-3 mm wide looks exactly like those of 10-16.
