TEENS. 



315 



oblong-lanceolate bi- 

 pinnate fronds four to 

 six inches long, nar- 

 rowed to both ends. 

 The upper surface is 

 slightly and the lower 

 densely glandular 

 hair}'. A native of the 

 Rocky Mountains. 



Cultivation. — When 

 grown in pots the 

 Woodsias should be 

 placed in thoroughly 

 well- drained loamy 

 soil mixed with small 

 pieces of porous ston(>. 

 They must be care- 

 fully guarded against 

 excessive moistarc, 

 and should not be 

 disturbed at the root. 

 On rock- work they like 

 a shady spot, and are 

 best wedged between 

 pieces of rock where 

 their roots can run 

 into the cool damp in- 

 terstices, and at the 

 same time be continu- 

 ously free from any- 

 thing approaching 

 stagnant moisture. 



The Aspidiums, 

 or Shield Ferns. — 



The Aspidiums do not 

 exhibit so marked a 

 range in the form and 

 cutting of the fronds 

 as many other genera, 

 but there are among 

 them many very de- 

 sirable and handsome 

 plants. As a rule, 

 the)' are less suited for 

 pot culture than for 

 planting out in the 

 rockery, either of the 

 in-door or out-door 

 fernery. As the genus 

 is here understood, 

 Cyclodium, Cyrto- 

 mium, and Polysti- 

 chum, to which latter 

 section the British re- 

 pref?entatives of the 



CySTOPTERIS FRAGILIS. 



Cystopteeis montanum.
