less ovate in outline, and sometimes .short-stalked, while the outer margin of the pinnoe 

 may be entire or incised, the latter condition when marked constituting var. incisum, Milde. 

 A Rocky Mountain specimen of Prof. Macoun's very closely approaches the form with 

 small, alternate, rounded and distant lobes, collected by Mrs. Rust in Onondaga County, 

 New York, while others from the same locality resemble B. simplex in having the sterile 

 segment distinctly petioled. Two plants from Bow River Pass, Rocky Mountains, show 

 the buds bursting for the new growth, which seems to be taking place before the old 

 fronds are withered, and specimens from Cape Rosier, Graspe, Que., in other respects typical 

 B. Lunaria, have the sterile segment scarcely overtopped by the fertile, and placed high up 

 on the plant, much as in B. matricariafoUum, the common stalk forming about three-fourths 

 of the total height. Some monstrous forms from Flat Creek, Manitoba, also gathered by 

 Macoun, are very stout and fully a foot high, with the fertile segment much branched, 

 the primary lower branches almost as long "as the fertile segment itself, while the sterile 

 segment is stalked and has its lobes, some of the lower of which are converted into 

 branched fertile pinnse, deeply incised. 



In ancient times B. Lunaria was credited with mysterious and magical powers for 

 opening locks when put into key-holes, taking the shoes off horses stepping on it, and 

 turning quicksilver into the genuine article, while even to the present day there are firm 

 believers in its powers of healing wounds to which it is applied.

This is a moderately lleshy, non-evergreen plant, two to twelve inches high, growing 

 commonly in dark, wet woods and along rivulets, but also found on rather dry and grassy, 

 elevated plateaus. Sterile segment petioled, placed above the middle of (usually high up 

 on) the plant, oblong-ovate in outline, and pinnate into 9-11 ovate, or ovate-oblong, obtuse 

 lobes, which are nearly all of one size and toothed or incised ; fertile segment bipinnate, 

 and generally short stalked; bud smooth, with the apex of both segments turned down, 

 the sterile segment clasping the fertile one by its side divisions, with its apex overlapping 

 the whole.
