178 COMMON CANADIAN WILD PLANTS. 



8. CAMPTOSO'RUS, Link. WALKING-LEAF. 

 C. rhizophyl'lus, Link. A curious little fern, growing in 

 tufts on shaded limestone rocks. Frond simple, with a very long 

 narrow point. Not very common. 



9. PHEGOP'TERIS, Fee. BEECH FERN. 



1. P. polypodioi'des, Fee. Fronds triangular, longer than 

 broad, 4-6 inches long, hairy on the veins, twice-pinnatifid, the 

 rhachis winged. The pinnoe sessile, linear-lanceolate in outline, 

 the loivest pair deflexed and standing forwards. Fruit-dots small 

 and all near the margin. Stipes rather longer than the fronds, 

 from a slender, creeping rootstock. Apparently not common, 

 but growing in rich woods near Barrie, Ont. 



2. P. hexagonop'tera, Fee. Fronds triangular, generally 

 broader than long, 7-12 inches broad. Pinnce lanceolate ; the 

 lowest very large, their divisions elongated and pinnatifid, the 

 basal divisions decurrent on the main rhachis and forming a 

 many-angled wing. Fruit-dots not exclusively near the margin. 

 Rich woods. 



3. P. Dryop'teris, Fee. Fronds broadly triangular in outline, 

 primarily divided into 3 triangular spreading petioled divisions, 

 smooth, the three divisions once- or twice-pinnate. Fronds from 

 4 to 6 inches wide. Fruit-dots near the margin. Rich woods; 

 common. Whole plant delicate, and light green in colour. 



1O. ASPID'IUM, Swartz. SHIELD FERN. WOOD FERN. 

 * Stipes not chaffy. 



1. A. thelyp'teris, Swartz. Fronds tall and narrow, lanceo- 

 late in outline, pinnate, the pinnse deeply pinnatifid, nearly at 

 right angles to the rhachis, linear-lanceolate in outline, the margins 

 of the lobes strongly revolute in fruit. Stipe over a foot long, and 

 usually longer than the frond. Common in low, wet places. 



2. A. Noveboracen'se, Swartz. Fronds much lighter in colour 

 than the preceding, tapering towards both ends, pinnate, the 

 pinnaB deeply pinnatifid, much closer together than in No. 1 , ami 

 not at right angles with the rhachis. Veins simple. Lower piniue 

 short and deflexed. Swamps.
