 I have not access to A. Canadensis, L. Syst. 12th cd. 3d appx. 176S. It may be 

 that this name should be used.

 loba. Lawson. Ranunc. 187c. 

 Rich upland woods; abundant. 



The first flower to appear in the spring, preferring northern slopes. 

 Watson's Index cites for Anemone Hepatica, var. acuta, Bigel. Fl. Bost. p. 135; 

 which is evidently an error as this name does not appear. The Index also cites Hepa- 

 tica triloba, var. acuta, Bigel. Fl. Bost. 2d ed. p. 222. What is really said is, ' He- 

 patica triloba, Q t Lobes acute." In Hooker, Fl. Bor.-Am. i. p. iS, is, " H. triloba , 

 J foliorum segmentis acutis " with synonym, "Anemone triloba, var. Q m acuta, 

 Bigel. Fl. Bost. cd. 2, p. 222," a combination which Bigelow does not use.
