straight, bluntish, rounded on the upper side at the base, rotundate- 

 cuneate on the lower side, with the upper edge sparingly piloso-denticulate 

 at the centre, ciliate at the base, the lower edge entire, the largest leaves 

 of the ultimate branchlets IV2 — 2 mm. long and V2 mm. broad; leaves of 

 the upper plane of the branches obliquely subfalcate-oblong, acuminate, 

 entire, rotundate-cuneate on the inner side at the base, produced on the 

 outer side, those of the ultimate branchlets to V*—l mm. long. Spikes 

 sohtary, 5 — 10 mm. long, I'A mm. diam. ; sporophylla deltoid-oblong, acute, 

 piloso-denticulate, slightly keeled, the largest 2 mm. long; macrospores 

 dirty-yellowish-white, rugulose with short or long, flexuose or branched 

 rumples on the basal side; microspores orange or yellowish, provided 

 with copious sessile, capitate projections on the basal side.

(36) S. slbnyanensis, Hiefon., Fed., Rep., X, 97. 



Shoots probably 50 cm. long, the lower part simple, stipitiform, 

 stramineous-green, quadrangular, rather compressed, to 3 mm. thick, the 

 upper part compound. Leaves heteromorphous; leaves of the lower plane 

 very unequal-sided and broadly obliquely ovate on the stem, falcate- 

 oblong on the branchlets ; those of the stipe ascending, remote, acuminate, 

 with the upper edge minutely denticulate, ciliolate in the broadly rotundate- 

 cuneate and pelluqid-margined lower half, ciliate at the subauriculate 

 base, the lower edge very minutely denticulate at the apex, sparingly 

 ciliate at the narrowly truncate base, the largest leaves 4V2 mm. long 

 and 2V2 mm. broad; those of the main and secondary rachises similar 

 but somewhat longer; of the main rachis spreading; of the branchlets 

 close, ascending, subacute or subobtuse, slightly spuriously veined, with 

 the upper edge sparingly piloso-denticulate and pellucid-margined in the 

 lower half, sparingly ciliolate towards the cuneate base, the lower edge 

 entire, or sparingly ciliate at the narrowly rotundate-cuneate base, the 

 largest leaves 2 — 2V2 mm. long, V2 — V* mm. broad ; leaves of the upper 

 plane erect, falcate-ovate, aristate-acuminate ; of the stipe remote, with 

 the outer edge involute, ciliate at the produced, auriculate base, the inner 

 edge minutely denticulate, ciliate at the base, the largest leaves 5 mm. 

 long, 2 mm. broad, the cusp Vs as long as the blade ; of the main rachis 

 incurvate-auriculate on the outer side at the base; cuneate on the inner 

 side at the base; of the branchlets similar, imbricate, entire, smaller, 

 rotundate-auriculate on the outer side at the base, the largest I'A mm.
