 stem the largest, 1 mm. long, V2 mm. broad, subspreading, those of the 

 branchlets more ascending; leaves of the upper plane Vs as long, ovate, 

 subacute, minutely denticulate on the inner side, rather entire on the 

 outer side, keeled. Spikes square or nearly so, short, to 4 mm. long, 

 1 mm. diam.; sporophylla erecto-patent, broadly ovate, subacute, minutely 

 and sparingly denticulate, those of the upper plane to 1 mm. long, of the
