Duplicates of Elmer's No. 13407, occurring in the Buitenzorg Herbarium, 

 have the main rachis 13 14 mm. broad including the lateral leaves, the 

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

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

 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 

 provided with sessile or stalked capitate projections.

 or obtusely angular, the upper part pinnately compound, the main rachis
