 ultimate branchlets 5 — 8 mm. broad, the lateral leaves more distinctly 

 serrulate towards the apex, the intermedial leaves with the cusp to V2 

 as long as the blade, the sporophylla more copiously serrulate throughout, 

 the macrospores white to pale-yellow-brown, with the apical ribs encircled 

 by a more or less distinct ring-shaped crest, the microspores more copiously
