No. 5.] GOODE — CANADIAN PERNS. 299 



Rhizoma dark-brown, creeping and closely beset with the 

 stumps of old fronds ; roots very wiry. 



Two plants of this neat variety were gathered last July on the 

 face of the exposed cliffs to the east of Cape Rozier, at an eleva- 

 tion of about 800 feet above the sea. 



Cystopteris fragilis, var. " B. Smalls — Fronds short, erect 

 and robust, 4 to 5 inches high, including the stalks, and from 

 f to \\ inches wide, firmer in texture than the common type, 

 and rather dull in color ; lanceolate or oblong-lanceolate in form, 

 pinnate or sub-bipinnate. 



Pinnge are lanceolate or ovate-lanceolate, the lowest pair rather 

 ■distant, contracted, and more erect. 



Pinnules oval or ovate, with obtuse or almost truncated apices, 

 minutely crenated or serrated on the margins, and the basal ones 

 joined together by a very narrow wing. 



Stalks stout, about IJ- inches long, or scarcely a third of the 

 length of the frond, reddish-brown, darkest at the base, becoming 

 paler and passing into green above the basal-pair of pinnae, 

 smooth but with a few large chaffy-scales at the extreme base. 



Veins forked or simple. Sori medial. 



Several plants of this variety were found on a limestone ledge 

 near Grand Greve, Gasp^. 



Cystopteris fragilis, var "^. Large.'' — Several plants were 

 found in the same locality as the foregoing, agreeing with 

 them generally, but having a more luxuriant growth, measuring 

 11 to 16 inches high, by IJ to 2 inches wide ; these I have 

 mounted separately. 



These large plants agree closely with the description of C. var, 

 dentata of Hooker. 



Cystopteris hulhifera, var. depauperata. — A dwarf form with 

 fronds only 2J- to 2f inches long, including the stalks, one fertile 

 frond bearing 3 bulblets, which induced me to include it, with 

 this species, although the sori were absent. 



Fronds pinnate, bipinnate towards base and pinnatifid at 

 apex, bright green and smooth, and acutely-deltoid in shape. 



Pinnse mostly horizontal, oblong-ovate above, more triangular 

 at the base. 



Pinnules oblong, obtuse and minutely toothed. 



Stalks scarcely as long as frond, or barely exceeding one inch, 

 and light-brown in color.
