 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 reallysald is, ' He- 

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

 A^ foliorum segmentis acutis " with synonym, "^4»^wo«(r triloba, var. j]^ acuta, 

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