texture membranaceous, firm, composed of very minute, linear, sub- 

 fusiform, translucent cellules; those at the base of the leaf (for three

 the lower ovate awnless, recurved at apex; the upper erect, convolute, 

 oblong, somewhat obtuse, hair-pointed, as in the branch-leaves; the 

 interior shorter, broader, usually awnless, with a pellucid repand

 linear paraphyses of very unequal lengths, and by filiform processes 

 (abortive leaves), double the length of the archegonia.
