Lastraea. — This species should be referred to the genus Dry- 

 opteris because of the présence of a few coarsely cancellated 

 (non-athyrioid) scales on the stipe and rachis, as in Asplenium, 

 i.e. the said scales hâve the cells decoloured and provided with 

 thick, brown side-walls.

Rhizome erect or suberect ; stipe and rachises provided with 

 flattened or subterete, deciduously ciliated orsetulose, linear-subulate 

 or needledike, squarrose setae leaving the stipe and rachis rough 

 by their persistent bases when they fall; rachis pubescent with 

 a Une of pale or whitish hairs down the upper side; indusium 

 small or rudimentary. — D. multiseta (Bk.) G. Chr. (v. A. v. R.,
