SADLERIA. 65 



3. Sadi.eria, Klfs. 



(Fke, Gex. Fil. tab. VII. A. fig. 1, 2.) Blechni sp., 

 Gcmdich., Brack. Woodwardice sp., Meiten. 



Suri linear, continuous on each side, parallel with and con- 

 tiguous to the costa. Involucre narrow-linear, suhcoriaccous, 

 attached to the outside of an elevated receptacle which crosses 

 the veins, opening towards the costa, at length patent. Veins 

 sunk, obscure, simple or forked, combined so as to form a 

 series of arches next the costa, the apices uniting with the 

 thickened margin of the segments. — Caudex 2 feet high, stout, 

 arborescent. Fronih tmifoiin, large, coriaceous, jnnnate ; pin- 

 na; pinnatifid, segments opaque, the margins recurved, serrated. 

 Stipites densely clothed with very long, narrow, sericeous, vil- 

 lose scales. 



I retain Sadleria as a genus rather on account of its peculiar habit or natural 

 character tliaii from any distinguishing mark derived from the fructification. The 

 sori resemble those of" Blechnum, but the involucre is more coriaceous and 

 persistent. The composition and texture of the frond are very ditfercnt ; and 

 judging from the very reduced figure of an entire plant in the Narrative of the 

 Voy. of the U.S. E.\pl. Exped. iv. p. 231, the mode of growth is quite that of a 

 Tree-fern.
