Mr. Watson observes that the T. palmata of the Atlantic States (of which this has 

 been hitherto mostly regarded as a variety) has more coriaceous strongly veined leaves, 

 the cauliue sessile, and the larger achenes (2 lines long or more) oblong-obovate, acute at 

 base, and abruptly beaked by the short style ; he also remarks that the Japanese form 

 has a narrowly ovate acheni>, more attenuate upward into the straightish style.
