preferred, however, to combine the two under the specific name, and have also included 
the synonymy of both under the same head. 
The Californian forms, var. Californicum, Eaton, and var. angulare, Braun, are, broadly 
speaking, distinguished from the type by the pinnæ of the former being less, of the latter 
more divided. In var. Californieum, which is more like a hybrid between A. muni- 
tum and A. aculeatum than anything else, the fronds are much elongated, scarcely narrowed 
at the base, and so little divided that even the superior basal segment is scarcely dis- 
tinct as a pinnule and is not at all auricled. In var. angulare the fronds, which are lighter 
colored and less stiff, rigid and prickly-looking, are scarcely or not at all narrowed at the 
base, and so much divided as to be truly bipinnate, the pinnules being distinctly short- 
stalked, mostly auricled, slightly incised, and the superior basal one often again pinna- 
tifid. Var. Braunii, Doell, differs in being less rigid and much thinner in texture, with 
shorter stalk, more narrowed base, and more divided pinnæ, the lower of which are 
obtuse; the pinnules, too, which are more distinct and auricled, have short stalks and 
truncate, rectangular bases, while the under or both sides of the fronds are covered with 
characteristic, long, soft hairs, which are absent or very scanty in true aculeatum. Var. 
scopulinum, D. C. Eaton, is readily recognized by its short, narrowly lanceolate, almost 
smooth fronds, which have ovate, rather obtuse pinnæ, with less aculeate teeth. 
Of a Canadian example sent him, Professor Eaton remarks :—“I have not before this 
seen anything just like your specimen. It is more exactly the European var. /obatum than 
any I have had from California, the difference being in the firmer texture of your plant, 
and the decidedly more aculeate teeth of the pinnules.” 
Heretofore the only forms of A. aculeatum known to be Canadian were vars. Braunii 
and scopulinum, the specimens now referred to the type having been received in 1886 from 
Mr. J. R. Anderson of Victoria, B. Col, who informs me they were collected in moist, 
rocky places at Port Simpson, on Portland Inlet, Northern B. Col. 
Genus XV.—CYSTOPTERIS, Bernh. 
2.—C. BULBIFERA, Bernh. ‘Very abundant about Lower St. John, Coldbrook,—Hay.” 
(Fowler, in Bull. Nat. Hist. Soc. N. B., No. IV.) 
3.—C. Montana, Bernh. Abundant for about one hundred yards along a spring 
brook, which ran through spruce woods, about ten miles from the H. B. Co.’s. post on Lake 
Mistassini, N. E. Terr.—J. M. Macoun. A few yards of soil on either side of the creek was 
covered with thick moss, in which, and up to the edge of the stream, grew the fern, the 
roots in some cases growing right in the water. Some of the specimens were very large, 
measuring about twenty inches in height. 
Genus XVI.—ONOCLEA, Z. 
1.—O. SENSIBILIS, L., var. OBTUSILOBATA, Torr. “ Richibucto,—Fowler; Havelock, 
King’s Co.,—Brittain.” (Fowler, in Bull. Nat. Hist. Soc. N. B., No. IV.)
