(52) S. ma^niflca, Warb., Mons., I, 114, tab. Ill A. 



Shoots ascending, to 50 cm. or more long, the lower part simple, 

 stipitiform, when dry angular, compressed, 4 mm. thick, the upper part 

 irregularly pinnate or 2 — 3 times forked, the branchlets 5 — 8 cm. long, 

 r/j cm. broad including the lateral leaves. Leaves subrigid, dark-green; 

 of the lower part of the stem subisomorphous, ovate ; of the lower plane 

 erecto-patent, broadly long-acuminate, of the upper plane narrowly short- 

 acuminate; leaves of the branched portion very heteromorphous ; lateral 

 leaves spreading, spaced in the lower part of the main rachis, close on 

 the branchlets; of the main rachis elongate-oblong, subfalcate, 6 — 8 mm. 

 long, obtuse, the upper side very minutely denticulate, rounded at the 

 base, the lower side very minutely denticulate towards the apex, for the 

 rest entire, or sparingly ciliolate at the subtruncate-rotundate-cuneate 

 base; of the ultimate branchlets similar, imbricate over the rachis, 8 — 10 

 mm. long, spreading; intermedial leaves erect, roundish-ovate; of the 

 main rachis very unequal-sided (conf Warburg's plate), 3 — 4 mm. long, 

 hardly oblique, shortly mucronulate-acuminate, subcordate at the base; 

 of the branchlets imbricate, broadly subfalcate-ovate, nearly 3 mm. long, 

 a little longer than broad, shortly acuminate, minutely denticulate, 

 sparingly ciliolate at the obliquely rounded base. Spikes 2 — 3-nate, square, 

 to 7 — 9 cm. long, 3 mm. diam. ; sporophylla elongate-ovate, Vh — 2 'A mm. 

 long, very acute, very minutely denticulate, often glittering; macrospores 

 yellowish-white, finely rugulose or reticulate; microspores provided with 

 conical or stipitate-capitate projections.

(53) S. bluuensis, e. A. e. «., Bull. Btz., 1918, XI, 29. 

 Shoots erect, or ascending from a creeping base, to 20 cm. long, the 



lower part simple or forked, the upper part branched, the stem I'A — 2 

 mm. thick near the base, terete, smooth or somewhat grooved, to 8 — 10 

 mm. broad including the lateral leaves; pinnae pinnate; pinnulae simple 

 or forked, or the largest sparingly pinnate; ultimate branchlets 7* — 2 cm. 

 long, 4 — 6 mm. broad. Leaves heteromorphous on both stem and branches; 

 leaves of the lower plane somewhat spaced on the stem, crowded on 

 the branchlets; of the stem horizontal, linear-oblong, bluntish, not or 

 indistinctly spuriously veined and pellucid-margined, the upper side 

 minutely serrulate but indistinctly so towards the apex, rotundate-cuneate 

 at the base, the lower side entire or obsoletely denticulate, narrowly
