Shoots erect, 1530 cm. long, the lower part simple, unequally 

 quadrangular, the upper part decompound, flabellate-deltoid ; lower pinnae 

 elongate, triangular, pinnately compound; ultimate branchlets contiguous, 

 ascending, 6 12 mm. long. Leaves of the lower plane rather contiguous 

 on the branchlets, spaced on the main rachis, more or less ascending, 

 green, pale-glittering beneath, ovate-oblong, 24 mm. long, 12 mm. 

 broad, subacute, spuriously veined, pellucid-margined and minutely den- 

 ticulate on the upper side, rounded, dilated and imbricated over the rachis 

 on the upper side at the base ; leaves of the upper plane Vi as long, 

 roundish or obovate, distinctly cuspidate, pellucid-margined and minutely 

 denticulate, somewhat obliquely cordate at the base. Spikes square, 

 512 mm. long, TA mm. diam. ; sporophylla ovate, finely acuminate, 

 pellucid- or pale-margined, minutely denticulate, keeled ; macrospores white, 

 finely rugulose-reticulate (? the apical ribs surrounded by a ring-shaped 

 crest); microspores provided with needle-like, bacilliform or stipitate- 

 capitate projections. 



Forma typica: Lateral leaves distinctly piloso-serrulate on the upper 

 side throughout, distinctly spuriously veined. 



Forma brevipes: Lateral leaves piloso-serrulate on the upper side 

 towards the base, entire or very obsoletely denticulate towards the apex, 

 less distinctly spuriously veined.

 approximate, subspreading, subacute, the base unequally cordate, with
