Shoots erect from a creeping base, 40 — 50 cm. long, the lower part 

 unbranched, terete, yellowish when dry, VU — 2 mm. thick, the upper 

 part branched; pinnae ascending, 8—10 on each side, the lower 2-pinnate,

 the edge; leaves of the branches heteromorphous ; those of the lower 

 plane spreading, suboblique, subcordate-ovate, 2 mm. long, subacute, 

 ciliolate at the base, denticulate on the upper edge in the lower half; 

 those of the upper plane erect, ovate, IV2 mm. long, acuminate, somewhat 

 keeled, denticulate; leaves of the branchlets similar but smaller; those 

 of the lower plane imbricate, rather rotundate on the upper side at the 

 base, cuneate-truncate on the lower side at the base. Spikes short, 3 — 5 

 mm. long, square, hardly 1 mm. diam.; sporophylla imbricate, nearly
