Vvooasia ilvensis (L.) R. j3r. 



SMALL, Kairy, linear-lanceolate compound leaves. 

 Pinnae very numerous, crowded toward tne top, ob- 

 vate to oblong, blunt, deeply cut into several oblong, obtuse 

 segments wnicn are sligntly scalloped. Son small and nu- 

 merous, near tke margins of tne divisions, somewhat confluent; 

 tlie very thin indusium attacked by its base under the sorus, 

 dividing into slender nairs which curl over tne sporangia. 

 Stems sbort, Kairy, stout, reddish, witb an obscure ]oint 

 about an inch from tne base, where tne leaves break off. 

 Rootstock stout. Leaves in tufts, a few mcnes long, tnick, 

 dark green, leathery; tne upper side generally smooth, the 

 lower thickly clotbed with coarse shining hairs which turn 

 rusty red at maturity. 



There are two woodsias in the Dells. This species is 

 very common, growing on dry rocks, often very much ex- 

 posed. The common name very appropriately describes the 

 mature leaves.
