Rhizome wide-creeping, the scales dense, linear-lanceolate, brown. Stipes 

 note, 15—60 c.M. long, polished, blackish, naked, scaly towards the base, 

 ! scales linear-subulate, spreading, crisped, leaving the stipes rough when

 rer ones branched again with 2—4 erecto-patent secondary branches. Leaf-
