Shoots wide-trailing, more or less flexuose, irregularly branched, the 

 stem semiterete or angular, often grooved, stramineous to grey-brown, 

 IVz 2% mm. thick; pinnae irregularly 2 3-pinnate with rather few 

 branchlets varying from V; to 2 cm. long. Leaves heteromorphous ; 

 leaves of the lower plane oblong; those of the main stem very remote, 

 horizontal or somewhat deflexed, 4 6 mm. long and 1Y 3 mm. broad, 

 subacute or shortly apiculate, rounded at the base but more broadly so 

 on the upper side, more or less piloso-denticulate on the upper edge, hot 

 or hardly imbricated over the rachis; those of the branchlets smaller, 

 more approximate, rotundate-cuueate, and the higher subbullate, at the 

 base, somewhat imbricated over the rachis, slightly ascending; leaves of 

 the upper plane erected, adpressed; those of the main stem remote, 

 broadly oblong, 2 3Vs mm. long, suddenly long-cuspidate, somewhat 

 keeled, denticulate or ciliolate, rounded at the base ; those of the branchlets 

 smaller, imbricate, more obovate, rather rbtundate-cuneate at the base. 

 Spikes single, rarely double, 3 12 mm. long, 3 4 mm. broad; sporophylla 

 of the upper plane ascending, lanceolate-oblong, more or less acute, 

 ciliolate, imbricate at the base, the lower ones somewhat larger. than the 

 higher; of the lower plane suberect, ovate, cuspidate-acuminate, ciliolate, 

 hardly smaller than those of the upper plane except the 2 4 lower, 

 which are much larger than the others and very unequal-sided, broadest 

 on the inner side; macrospores pale-reddish, ochraceous or whitish, nearly 

 smooth; microspores whitish, reddish or brown, irregularly verruculose.
