ADDITIONS TO CANADIAN FILICINEAS, 13 
narrow-oblong, strap-shaped, truncate at the base; attenuate at the apex, the margin 
inciso-lobate ; fertile; the epidermis of the under surface also developed near the mar- 
gin into a lobed, excurrent membrane, which bears sori on both surfaces.” In the New 
Brunswick specimens, the peculiar lobed, excurrent membrane is well marked, and gives 
the frond the appearance of being double, i. e., as if two fronds, both soriferous, had been 
pasted together, the one on top of the other. The layer corresponding to the frond proper 
slightly exceeds (one-sixteenth to one-eighth of an inch) that from the epidermis, and is 
lobed and dentate. The only deviation, which is of little account, from the description, is 
that the base is heart-shaped and auricled instead of truncate. SS. vulgare is occasionally 
seen with sori on the upper as well as the under surface of the fronds, which abnormality 
sometimes proceeds from the normal sori being prolonged round the margin; but at 
others they are produced on the upper side within the margin, and without correspond- 
ing ones beneath. This freak, caused in the first of these ways, is a marked feature in 
some of the Woodstock specimens of var. marginatum, which have thus four soriferous 
surfaces instead of the usual three. 
Var. RAMOSUM, Gray. (Moore’s Nature Printed British Ferns, IJ, pp. 140 and 195 ; 
Handbook of British Ferns, 3rd ed., 199.—S. officinarum, Swz., var. ramosum, Willd.) Mr. 
Jack’s specimens closely approach this variety, which is said to be constant in cultivation 
and reproduce itself from spores, being characterized by their short fronds having the 
stipes branched, the branches, which start singly from the stipes, becoming ramified like 
the branches of a tree, and ending in crisped tufts. 
Var. MULTIFIDUM, Gray. (Moore’s Nature Printed British Ferns, I, pp. 140 and 188 ; 
Handbook of British Ferns, 3rd ed., 198.—S. officinarum, Swz., var. multifidum, Schk.) In 
this form the stipes are unbranched, but the fronds are furcately divided at the apex, and 
these divisions are few—to many—cleft at their points. 
Genus XI1J] —PHEGOPTERIS, Fee. 
1.—P. ponypopioipEs, Fe. Rather rare near the line of the C. P. Ry. in the valley 
of Beaver Oreek, Selkirk Mountains, B. Col., both along this stream on stumps, and on 
rocks along mountain torrents near Stony Creek.—Macoun. “Shaded, rocky places, Port 
Simpson on Portland Inlet, Northern B. Col—J. R. Anderson. 
2.—P. HEXAGONOPTERA, Fee. In rich woods, not common, just east of the Water- 
works Reservoir, Toronto, Ont.—Burgess. 
4.—P. cALCAREA, Fee. Not rare in rather low woods at the base of limestone cliffs, 
and in crevices of the cliffs themselves, at the mouth of Temiscami River, Lake Mistassini, 
N. E. Terr.—J. M. Macoun. 
5.—P. aupestris, Meit. The finding of this species in British Columbia, by Professor 
Macoun, in August, 1885, is strongly confirmatory of its having been originally collected 
by Dr. Lyall in the Cascade Mountains of the same province. It grew abundantly, at an 
altitude of 7000 feet, in wet places on the slopes of the glacier mountain along Bear Creek 
at the summit of the Selkirk Mountains, near the line of the C. P. Ry. The stalks of most 
of these specimens are long in proportion to the size of the plants, in the largest making
