Shoots erect, 15 — 30 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 contigijpus 

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

 green, pale-glittering beneath, ovate-oblong, 2 — 4 mm. long, 1 — 2 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 Vs as long, 

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

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

 5 — 12 mm. long, I'A 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.

Shoots erect from a decumbent base, to 30 cm. more or less long, 

 the . lower part simple, more or less angular, yellowish-grey, 1 V2 — 2 mm. 

 thick, the upper part pinnately compound; pinnae 6 — 10 on a side, the 

 lowest the longest, 10—15 cm. long, copiously 2 — 3-pinnate; ultimate 

 branchlets crowded, 6 — 12 mm. long, 3 — 4 mm. broad including the lateral 

 leaves. Leaves of the stipe erected, adpressed, triangular or triangular- 

 oblong, remote, to 4 mm. long, entire, acute, the base cordate, the basal 

 lobes hamato-incurvate, ciliolate ; leaves of the branched portion hetero- 

 morphous; leaves of the lower plane broadly lanceolate-oblong, subfalcate, 

 bronce-green above, pale beneath; of the main rachis 4—5 mm. long, 

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

 the basal lobes hamato-incurvate, the upper one the largest, or the lower 

 more rotundate, the upper edge minutely denticulate towards the base,
