pinnate or subpinnate in the upper part, the stem filiform, 4— 4Vj mm. 

 broad including the lateral leaves; ultimate branchlets short, 3 mm. broad. 

 Leaves heteromorphous ; lateral leaves distinctly, though not very, remote ; 

 of the main stem horizontal, unequal-sided, roundish or broad-oblong, 

 bluntish, subentire or sparingly and very minutely serrulate towards the 

 apex, the upper side very minutely serrulate in the lower half, rounded 

 or broadly rotundate-cuneate at the base, the lower side subentire towards 

 the rotundate-cordate base, the largest leaves 2 mm. long by I'A mm. 

 broad; of the branchlets smaller, ovate, relatively narrower, somewhat 

 more distinctly serrulate on the upper side, narrower at the base; inter- 

 medial leaves erect, more or less remote, ovate, long-subcuspidate- 

 acuminate, more or less sparingly and minutely serrulate, obliquely 

 rounded or rotundate-cuneate at the base, the largest leaves 1 mm. long. 

 Spikes solitary, 1 — IV4 cm. long, 2 — 2V2 mm. broad; sporophylla of the 

 upper plane spreading, unequal-sided, subsemiovate, acute or shortly 

 acuminate, rather sparingly and minutely serrulate, keeled, the largest 

 r/2 mm. long; of the lower plane suberect, triangular-ovate, long-acuminate, 

 sparingly and minutely serrulate; macrospores cream-yellow or yellowish- 

 white, densely and minutely punctulate-verruculose ; microspores 



Negros. 



(120a) S. apoensis, JK«fo»., Leafl., YI, 2028. 



Shoots creeping and repeatedly dichotomous in the lower part, sub- 

 ascending and sparingly pinnate in the upper part, the stem very slender, 

 under 'A mm. thick, compresso-subterete ; ultimate branchlets 2 — 2'/4 mm. 

 broad including the lateral leaves. Leaves heteromorphous; lateral leaves 

 of the lower part of the stem remote, ascending, to 1 mm. long by V* 

 mm. broad, oblique-oblong, shortly mucronulate, the upper side long-ciliate, 

 minutely serrulate at the apex, slightly pellucid-margined in the lower 

 part, rounded or rotundate-cuneate at the base, the lower side minutely 

 serrulate, sparingly ciliolate at the rotundate-cuneate and broadly adnate 

 base; of the branches larger, to 2 mm. long by 1 mm. broad, approximate 

 or somewhat remote, obliquely rotundate-truncate at the base, the lower 

 side less serrulate; intermedial leaves small, ovate, unequally (obliquely) 

 cuneate or rotundate-cuneate at the base, sparingly ciliate, cuspidate- 

 acuminate, the cusp hair-pointed. Spikes solitary on the branchlets, 'A — 2 

 cm. long, IV2 mm. broad; sporophylla of the upper plane ovate, to 

 I'A mm. long, acute, rostrate, minutely serrulate at the apex, long-ciliate,
