 smaller, approximate or contiguous, keeled. Spikes solitary on the

 sporophylla of the upper plane ascending, close or approximate, the higher 

 somewhat imbricated, narrowly lanceolate, subfalcate, obscurely acuminate, 

 more or less distinctly denticulate, conspicuously keeled, the keel ciliated 

 towards the base ; those of the lower plane erected, imbricated, lanceolate- 

 ovate, subcuspidate (long-acuminate), ciliated, keeled; macrospores whitish, 



smooth or nearly so (obsoletely rugulose); microspores

Shoots trailing, repeatedly forked, rather caespitose ; secondary shoots 

 4 7 cm. long, with the main rachis Vs mm. thick, yellowish when dry; 

 pinnae remote, r/ 2 2 cm. long, sparingly branched; branchlets 1 cm.

 obtuse, dilated, rounded, denticulate to ciliolate and imbricated over the 

 rachis on the upper side at the base ; of the upper plane erect, ovate, 

 shortly cuspidate, denticulate, nearly keeled; leaves of the branchlets 

 similar to those of the main rachis but smaller, more close, often imbricate.
